If It's a Hack and It Works, Is It Really a Hack?

I have a couple servers at home — one running Proxmox VE and one running Proxmox Backup. I use the VM server when I need to spin up a development environment, for running the odd game server, serving files locally, running Home Assistant, etc. I also like to donate spare cycles to Folding@Home. The backup server of course is in case I do something stupid on the VM server.

There's just one problem with that. My second-hand 8-year-old dual-Xeon server runs hot.

It was too much to keep running in my home office. Between the two servers, my desktop, and my work laptop, I was regularly seeing ambient temperatures around 26°C. It was just too warm for comfort.

Last summer I moved my network gear and the two servers into the front coat closet. This was great for me working in my home office, but not so great for my servers. Despite adding a passthrough vent to the closet door and a vent fan to the ceiling, the closet was still consistently in the 26°-30°C range.

The ideal solution would probably be to use an enclosed server rack and run an exhaust vent up from the top. Unfortunately, rack-mount server cases are expensive, enclosed racks are very expensive, and my closet is too small for that anyway.

So I hacked together a solution.

I built a frame out of some cheap 1x2 lumber and wrapped a piece of thin sheet steel around the sides to make a crude plenum. On top, I added a 10x6 register box with a semirigid vent hose coming out of it. This gives me a guide for drawing air out of the servers and guiding it up to the vent fan in the ceiling.

To help things along, I added a 120mm fan inside the register box. But not some whisper-quiet Noctua. This is (if the Amazon listing is to be believed) a 5000 RPM, 210 CFM monster of a fan. It's loud, but moves a lot of air.

Too loud in fact. Its droning could not be silenced by any mere closet door. I had to add a PWM fan speed controller to calm it down. It's a cheap unit from Amazon, but it came with a temperature probe and it has a configurable operating range.

The result? Where previously the entire closet was consistently above 26°C, now it's staying around 23°. There is a difference of 5°C between ambient in the closet and the air inside the exhaust duct, so it is doing its job of redirecting the hot air from the servers.

I call that a successful hack.

How to Implement Proxmox VM Backups with NAKIVO Backup & Replication: A Comprehensive Guide

Backing up virtual machines (VMs) is a must for businesses that depend on reliable data access and uninterrupted operations. Proxmox, a popular virtualization platform, offers flexibility for running VMs, but without a strong backup plan, even the most robust virtual environments can fall short in an emergency. That’s where NAKIVO Backup & Replication comes into play, making the backup and recovery process simpler and more secure.

In this guide, we’ll walk through how to set up backups for Proxmox VMs using NAKIVO Backup & Replication in a clear, step-by-step way. This tutorial is for anyone from small business owners to IT teams looking to establish reliable and automatic backups that protect their data without complicating their workflow.

Why NAKIVO Backup & Replication is a Great Fit for Proxmox Users

NAKIVO Backup & Replication is highly rated by companies and IT professionals for good reason—it’s both powerful and user-friendly, making it an ideal choice for protecting Proxmox VMs. Here are some key benefits of using NAKIVO with Proxmox:

Speed and Efficiency: NAKIVO’s backup process is fast and effective, allowing you to keep your systems protected with minimal downtime.

Budget-Friendly: It offers flexible pricing and smart data-saving features, like incremental backups, which help keep storage and operational costs down.

Flexible Backup Options: You can tailor your backup schedule and choose where to store backups, from local drives to network storage, giving you options as your business needs grow.

Ransomware Protection: With built-in encryption and advanced access controls, NAKIVO safeguards your backups against threats like ransomware.

With these benefits in mind, let’s dive into the steps to set up Proxmox VM backups using NAKIVO.

Step 1: Get Your Proxmox Environment Ready

Before we jump into the setup, it’s essential to make sure your Proxmox environment is properly configured. Here’s a quick checklist:

Update Proxmox: Always ensure you’re running the latest version of Proxmox, as updates often include important security and compatibility improvements.

Install Necessary Modules: Confirm that modules like QEMU and LVM are installed. These modules are important for managing VMs and are essential for smooth backup operations.

Choose Your Storage: Decide where your backup data will go. For companies with multiple VMs, a network-attached storage (NAS) solution or external drive will make it easier to manage large volumes of backup data.

Step 2: Install NAKIVO Backup & Replication

Once your Proxmox setup is ready, it’s time to install NAKIVO Backup & Replication. This software works on multiple platforms, so choose the one that best fits your system.

Download the Installer: Visit the NAKIVO website and download the installer. NAKIVO provides options for different environments, like Linux, Windows, or a NAS device.

Run the Installation: Once you’ve downloaded the installer, follow the instructions specific to your operating system. For Linux users, this might mean running a few terminal commands; on Windows, it’s usually a simple setup wizard.

Access the NAKIVO Dashboard: After installation, open a web browser and log into the NAKIVO dashboard using the default login credentials provided. The dashboard is where you’ll set up and monitor backups.

Step 3: Connect Proxmox to NAKIVO

With NAKIVO installed, the next step is to link it to your Proxmox environment so it can locate and interact with your VMs.

Add Proxmox to Inventory: In the NAKIVO dashboard, go to “Inventory” and click on “Add New.”

Select Proxmox as Hypervisor: Choose “Proxmox” from the list of available hypervisors. This selection tells NAKIVO to look for Proxmox servers in the network.

Enter Proxmox Server Credentials: Input the IP address and login credentials for your Proxmox server to enable access.

Verify Connection: NAKIVO should now recognize your Proxmox VMs in the dashboard. If you see them listed, you’re all set to start configuring backup jobs.

Step 4: Set Up Backup Jobs for Your VMs

Now that NAKIVO and Proxmox are connected, it’s time to configure the actual backup jobs that will keep your data safe.

Create a New Backup Job: In the NAKIVO dashboard, click on “Create” and select “New Backup Job.” This is where you’ll define settings for each VM’s backup.

Select VMs to Include: Pick the VMs you want to back up. You can choose individual VMs or entire groups if you want to save time and back up multiple VMs at once.

Define a Backup Schedule: Decide how often you want to run backups. For critical data, daily backups are ideal; less crucial data might be backed up weekly. NAKIVO also offers incremental backups, which only back up changes since the last backup, saving time and storage.

Choose Backup Storage: Select where to store your backups. Options range from local storage to network drives, or even the cloud if that’s an option for your business.

Set Retention Policies: Retention policies help manage storage by automatically deleting older versions of backups. This allows you to keep recent versions without overloading your storage.

Step 5: Explore NAKIVO’s Advanced Features

NAKIVO offers advanced features that help you get more value from your backups:

Ransomware Protection: Encrypt your backups and restrict access to them to prevent data loss in case of a ransomware attack.

Data Compression: NAKIVO’s compression feature reduces backup size, which is especially helpful if you’re working with limited storage.

Automated Reporting: Configure automated reports to keep you updated on backup status, job completion, and any potential issues, so you’re always in the loop.

Step 6: Test and Verify Your Backups

Testing backups might seem like an extra step, but it’s essential to ensure that your data can be restored correctly when needed.

Run a Test Restore: From the NAKIVO dashboard, try restoring a backup to verify it’s complete and functional. This test gives you peace of mind that the data is usable in case of an emergency.

Check for Data Integrity: Make sure all your critical files and data are present and undamaged in the restored backup. Regular testing helps ensure reliability.

Schedule Routine Tests: If you manage a lot of VMs, it’s a good idea to test backups periodically. Quarterly tests or tests after significant system updates keep you prepared for any data recovery scenarios.

Step 7: Monitor and Maintain Your Backup System

After setting up your backup jobs, keeping an eye on backup performance and identifying any issues will help maintain a dependable system.

Set Up Alerts: Configure alerts to notify you of backup issues, like job failures or storage capacity warnings. Alerts can be sent by email or SMS for convenience.

Review Backup Reports Regularly: NAKIVO’s detailed reports let you see how your backups are performing, providing insights into any potential issues or storage usage trends. Regularly reviewing these reports helps keep your backup strategy effective.

Pro Tips for Optimizing Proxmox VM Backups

Here are a few final tips to help you maximize your Proxmox backup strategy:

Use Multiple Backup Locations: Storing backups in multiple locations (e.g., local storage and cloud storage) adds an extra layer of protection against data loss.

Stay Updated: Make sure both Proxmox and NAKIVO Backup & Replication are updated regularly for optimal security and performance.

Tailor Backup Schedules by Priority: Some VMs are more critical than others, so back up essential systems more frequently than less critical ones to save storage and backup time.

Airwaves (Or, how I learned to stop worrying and love the aircraft on my screen

Admittedly, I'm a bit of a fan of aviation. Most forms of transit actually, but that's for a different blog. I like aircraft. They've always fascinated me, and at a point, I'd wanted to get my pilots license.

I just think they're neat. I enjoy flying, I enjoy the intricacies of the taxiing, the take-off, the landing, and hopefully enjoying in-flight wi-fi in-between. I enjoy seeing and knowing the ins and outs of how I get from Point A to Point B via plane.

So what better way to enjoy two things at the same time, than by mixing my fascination of aviation with my passion for technology! I was shown this by a colleague at a past workplace, and I just HAD to have one myself. Below, I'll be chronicling my journey, experience, frustrations and wins with tracking aircraft in my area over ADSB.

Our adventures begin with this little nugget - I figured I'd start small and assuming all goes well, I'd scale up. Here's what it looked like initially

Not bad - just on 100nmi of range.

Once I moved to this arrangement, I was getting no more than 25nmi to the south, but got over 100nmi to the north, which was a pleasant boost, no doubt helped by the wall.

I invested in a RadarBox ADS-B FlightStick and the associated dipole antenna.

25nmi to the south, and more than 135nmi to the north. A sound improvement, but we can do better!

And it starts with the roof!

Much improved coverage all-round! 107nmi to the west, 162nmi to the east and north, and around 80nmi to the south. The Pi was in the roof, running off a POE Spliter

This is where I begin to have issues though.

POE Splitter burn-outs

SD Card corruptions

The Airnav stick not being recognised

So I get through the POE Splitter burnouts by getting another one. I get another ~2-4 weeks out of that one. Then the SD Card dies. I swap it over and get about 2 months. Then it dies. Amongst this, the Airnav stick is being less than helpful and is not consistently picked up by the Pi.

Not good.

So where to from here? I saw a few options:

Try and have the Pi network boot the ADSB feeder image from a server

Get another SD card and go again

Try USB over Cat 6 converters and do it that way

Install an Active USB Extension cable

Option 2 was the last option - I really didn't want to go down this route because it's just me purchasing SD cards again and again and restoring backups and I have better things to do.

Option 1 was the first idea - it keeps the power and network up near the AirNav stick and is what I experimented with first.

I found that I was not able to get much love with that - mostly involved with trying to get rootFS off the SD card was painful and difficult and was abandoned after a weekend.

This led me to option 3 - try some USB over Cat converters and give that a go. I'll virtualise the ADSB receiver as a VM in ProxMox and do it that way. And I did - I picked up these promising DOSS USBCAT100 dongles, which on the product page spec sheet advise that USB 2.0 full power/speed can be done up to 50 metres. They arrived, yay, happy days! I thought "before I get up in the roof and use these and find out they may not work, I better test these", and so I did, with my iPhone and a 1.5 metre Cat 6 cable only to see...

Wonderful. It's USB 1.1 speeds. Not great. The common consensus if you look up USB speeds and RTLSDR sticks is that they need USB 2.0 speeds, so this can't be used, and I had to get a return.

So I went for option 4 - a 15M Active USB Extension Cable from 4Cabling. I got up in the roof and ran that cable from the rack to the spot, plugged the AirNav stick in and connected the server and... Something...ISH? The stick fired up, but the light on the stick was flickering, and the data activity lights on the USB cable were not consistent either. Eventually both got settled and off we went.

Off we went to not too much luck. Every 2-6 hours, the stick would fail/stop and not be recognisable by the host.. How annoying... No mix of USB 2.0 or USB 3.0 ports would work. Rebooting the ProxMox host didn't yield any wins - I had to shutdown and power on every time this happened. Thinking it may be power related, I got one of those USB splitter cables that shipped with many external HDDs of yore (pre-USB 3.0 days) to see if that would make a difference.

And it did, again briefly. No mix of 2.0 or 3.0 ports worked, but I DID have some better luck with using a USB power bank on the power-only cable, but that failed again (just after a longer time period), and so did using an Apple 10W USB Power Brick. A 12W Apple Power Brick also didn't work.

So, now with seemingly nothing else to try, I went with a FlightAware Pro Stick Plus. It's been installed for over a week now and is happily plodding away! I'm getting coverage of more than 200nmi north, getting around 175nmi east, more than 100nmi south, and 125nmi west. The amount of hits is also much more consistent.

For reference, for my aircraft tracking, I use adsb.im to track and feed. Make sure you take backups early and often!

SysAdmin Sunday

One of my ProxMox hypervisor machines has a failing disk. Of course, it's the disk that stores the root filesystem of my homelab DNS server.

remediated by pulling a backup of running Pi-hole and restoring to the other hypervisor, running from an NVME drive now.

The best thing about running a Pi-hole, besides the whole house ad blocking thing, is the skinnable interface.

The Network File System (NFS) is a well-proven, widely-supported and standardized network protocol used to share files between separate computer systems. The Network Information Service (NIS) is commonly used to provide centralized user management in the network. When NFS is combined with NIS, you’re able to have file and directory permissions for access control in the network. The default configuration of NFS is to completely trust the network and any machine connected to a trusted network is able to access any files that the server makes available. In Proxmox Virtualization Environment you can use local directories or locally mounted shares for storage. A directory is a file level storage that can be used to store content type like containers, virtual disk images, ISO images, templates, or backup files. In this post we discuss how you can configure NFS share on Proxmox VE for ISO images. The same process applies for any other storage purpose like storage of virtual disk images and templates. In Proxmox VE, storage configurations are located in the file /etc/pve/storage.cfg. You can list contents in /var/lib/vz/ directory: $ ls /var/lib/vz/ dump images template Within templates directory we can see iso and cache sub-directories. $ ls /var/lib/vz/template/ cache iso The table below shows a predefined directory layout to store different content types into different sub-directories Content type Subdir VM images images// ISO images template/iso/ Container templates template/cache/ Backup files dump/ Snippets snippets/ Configure NFS server Share Login to the server that will act as NFS server and configure export for ISO contents. If you’re using a ready solution with NFS feature, you can skip this steps. Install NFS server package on your Linux system. ### RHEL Based systems ### sudo yum -y install nfs-utils sudo systemctl enable --now rpcbind nfs-server sudo firewall-cmd --add-service=nfs --permanent sudo firewall-cmd --reload #If use NFSv3 allow the following sudo firewall-cmd --add-service=nfs3,mountd,rpc-bind --permanent sudo firewall-cmd --reload ### Debian Based systems ### sudo apt -y install nfs-kernel-server Let’s now configure NFS export by editing the file below $ sudo vim /etc/exports /nfs/isos *(rw,no_root_squash,no_subtree_check) In the example we’re setting /nfs/isos as NFS share for ISO images on Proxmox VE. Confirm it works after the changes by re-exporting shares: $ sudo exportfs -rrv exporting *:/nfs/isos Mount NFS ISO share on Proxmox VE server Install NFS utility packages in your Debian / Ubuntu system. sudo apt -y install nfs-common Our NFS server setup is: NFS Server IP address: 172.20.30.3 ISO Export path on NFS Server: /nfs/isos Ensure you don’t have any data inside isos directory: ls /var/lib/vz/template/iso/ On Proxmox VE, which acts as NFS client, execute the following to display RPC information of the remote NFS server. $ rpcinfo -p 172.20.30.3 program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100005 1 udp 20048 mountd 100005 1 tcp 20048 mountd 100005 2 udp 20048 mountd 100005 2 tcp 20048 mountd 100024 1 udp 46068 status 100024 1 tcp 43599 status 100005 3 udp 20048 mountd 100005 3 tcp 20048 mountd 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 3 tcp 2049 100003 3 udp 2049 nfs 100227 3 udp 2049 100021 1 udp 44453 nlockmgr 100021 3 udp 44453 nlockmgr 100021 4 udp 44453 nlockmgr 100021 1 tcp 35393 nlockmgr 100021 3 tcp 35393 nlockmgr 100021 4 tcp 35393 nlockmgr

Run the showmount to display all active folder exports in an NFS server: $ showmount -e 172.20.30.3 Export list for 172.20.30.3: /nfs/isos * Option 1: Configure mount using Proxmox pvesm (Recommended) pvesm is a powerful Proxmox VE Storage Manager command line tool. Use the tool to scan for NFS shares in the server we just configured. $ sudo pvesm scan nfs 172.20.30.3 /nfs/isos * We’re going to run commands shared below to configure NFS Storage for ISO images on our Proxmox environment. sudo pvesm add nfs NFS-iso --server 172.20.30.3 --path /var/lib/vz/template/iso/ --export /nfs/isos --content iso Where: 172.20.30.3 is the IP address of NFS server /nfs/isos is the path to the iso folder on NFS server (NFS export path) /var/lib/vz/template/iso/ path on Proxmox server where NFS share is mounted Listing contents of /etc/pve/storage.cfg after command execution. $ cat /etc/pve/storage.cfg dir: local path /var/lib/vz content iso,vztmpl,backup lvmthin: local-lvm thinpool data vgname pve content rootdir,images nfs: NFS-iso export /nfs/isos path /var/lib/vz/template/iso/ server 172.20.30.3 content iso We can confirm new lines were added to the file. With the df command you can check if mounting was successful. $ df -hT /var/lib/vz/template/iso Filesystem Type Size Used Avail Use% Mounted on 172.20.30.3:/nfs/isos nfs4 400G 39G 341G 11% /var/lib/vz/template/iso Option 2: Configure mount using /etc/fstab You can also use mount command for runtime testing if Proxmox server can access NFS server and exported directory. sudo mount -t nfs 172.20.30.3:/nfs/isos /var/lib/vz/template/iso/ To persist the configurations use /etc/fstab file. $ sudo vim /etc/fstab # Add NFS ISO share mount 172.20.30.3:/nfs/isos /var/lib/vz/template/iso nfs defaults 0 0 Unmount before testing: sudo umount /var/lib/vz/template/iso Validate mounting can be done successfully sudo mount /var/lib/vz/template/iso Check with the df command: $ df -hT /var/lib/vz/template/iso/ Filesystem Type Size Used Avail Use% Mounted on 172.20.30.3:/nfs/isos nfs4 400G 20G 360G 6% /var/lib/vz/template/iso Login to Proxmox Web dashboard and check the status of your mount We can see a list of images available on NFS share. From here VM installation with the ISOs can begin.

TOP THINGS TO CONSIDER BEFORE STARTING YOUR VPS HOSTING BUSINESS

FIND A RELIABLE PROVIDER

In a nutshell, the alternative plan is to rent one or more servers from an existing hosting provider, set up a control panel to resell VPS from, and then sell them to customers.

This will allow you to significantly cut costs and actually start a hosting business with a modest investment.

In order to succeed, you have to find an established provider that offers cheap prices and has reliable services at the same time.

FOCUS ON A NICHE

Forget about selling generic VPS services, the competition is simply too high. You’ll have to target a specific niche; a proper market research will help you find one.

Since a few servers are easier to manage than a large number, you could focus for example on a very fast support response time, and charge premium prices for premium support. Make sure that you honor your promises if you take this route.

Alternatively, you might want to consider selling VPS servers to a crowd or niche that you’re particularly familiar with. Perhaps you’re part of a gaming community that needs VPS servers on a frequent basis. Or perhaps you’re a developer or data scientist who needs servers to run your software, and you know other colleagues who have the same need.

The possibilities are endless, and the key advantage of taking this approach is that you can speak very clearly in a language that your customers will understand (because you’re one of them!).

DESIGN YOUR INFRASTRUCTURE

After you buy your servers from a hosting provider and have a target in mind, it is time to create your VPS infrastructure.

You’ll have to design several packages, with a number of CPU cores and various amounts of RAM and disk space.

To make things extra easy, you can simply buy cheap VPS servers from a provider and resell them as is (without needing to set custom CPU or RAM, and just using the specs provided by your hosting provider for each VPS).

These packages can be target-specific; there are for example some applications that don’t need much CPU power but use a lot of memory.

In addition, you can install software or tools on top of the hardware, for example a CMS like WordPress. Offering obsolete packages, such as php 5.3, can also be an interesting niche for people who want to keep old websites online.

In order to create the actual virtual machines, there are several virtualization options. KVM and VMware are free and offer good performance, but most customers want some kind of control panel.

You can try to use one of the free hosting panels like Vesta or ISPConfig, but these can be buggy and require good technical skills for operation and maintenance.

Another alternative is to use Proxmox, which has an open source version that is very stable and offers both KVM and LXC virtualization.

If you want to resell shared or reseller hosting, instead of fully-fledged VPS servers, the safe options are WHM/cPanel and Plesk, which are very reliable and stable control panels. While Plesk is a little cheaper and can be installed on more operating systems, WHM is the best panel on the market and has great features and support.

AUTOMATE BILLING

If you start small and only have a few customers, you can use an open-source suite to manually handle billing.

Later, as your business grows, this will no longer be an effective option. There are several billing applications on the market that are especially designed for hosting companies and integrate with platforms such as WHM.

The best of these are WHMCS and Blesta, both have a form of free trial that you can use to test them and choose the one that suits best the needs of your company.

MANAGE YOUR INFRASTRUCTURE

Every hosting provider must have at least three basic systems in place: active monitoring, backups and a support ticketing platform.

There are both free and paid alternatives for all of these; you should try the open source options first, these include Nagios, Cacti, Zabbix (monitoring), Bacula, UrBackup (backups), or osTicket (for customer support).

Keep in mind that the open source systems are free but installing and configuring them can be quite difficult.

A central systems management solution like Spacewalk can make your life easier.

HANDLE SPAM AND ABUSE

Allowing abuse from your servers can ruin the reputation of your company, so you must prevent it.

WHM and Plesk include dedicated tools that detect and limit spam and other malicious activities. If you don’t use one of these panels, you’ll have to configure your monitoring system to alert you of any suspicious network traffic.

If you need an open source tool to handle your abuse requests (for SPAM, DMCA, and so forth), a good option is to setup a dedicated abuse email (IE, abuse@domain.com), and then forward all mail into a tool called abuse.io. It’s an open source software that helps you manage abuse requests that come via email.

CLOSING THOUGHTS

Starting a hosting company as a reseller is a very good idea because you can gain invaluable experience without risking a lot of money.

Many major players in the industry have actually started as resellers and then expanded their business, you can use the same strategy to test your management skills and build a solid platform for future growth.

Fstrim on Ubuntu 18.04

Recently I discovered that my backups of my proxmox virtual machines were taking up too much space on my storage server. After doing some research, i found out that I could run fstrim -v / to remove deleted space from my drive. Now what I needed was a way to automated it. Using Cron I was able to make it run every 30 min and generate a log file, to verify and make sure its working correctly. But…
