Hey there, I have a (very) small Ubuntu server and I was dabbling on the idea to do system backups (entire system, meaning, if the disk of the said pc fries, I can get another one, put the info from the backup on the new disk, works immediately afterwards). I have a couple of Linux mint machines and a windows one. I searched a lot out there and found several names, from rsync to Borg backup.But ultimately I don’t really know if these solutions would fit my use case.
So the question is: is there a feasible way/service that can be self hosted to do backups of local machines, similar to an image backup? Or, if you believe there are better ways to do it, can you please mention it?
Thanks in advance

I think Borg Backup would fit your needs. You would still need to reinstall things like a boot sector and recreated partitions but on the other hand file based backups have the advantage that you can restore individual files when needed too and that it is easier to only backup what changed. Just make sure to exclude any temporary files you don’t want to keep from the backup (e.g. cache dirs, log files that get rewritten often and aren’t relevant long-term,…).
you could use btrfs snapshots of the volumes you want to preserve. then send the snapshot to a remote location.
if the ssd fries you just need to download the snapshots and restore their layout.
i have a script for it and i use it on my server: https://github.com/simone-viozzi/btrfs2cloud-backup
I use Veeam Backup & Recovery Community Edition. If you’re runing VM’s you have to be on VMWare or Hyper-V. You can also use agents on the individual VM/Server. It also requires a pretty hefty Windows host, at least if you want your backups to complete fairly quickly.
Those are understandably downsides for some people. But, Veeam is in a class by itself. It has no serious competitors and as far as ease of use and reliability, it’s top tier.
I’m lazy. I don’t want to spend a bunch of time configuring finicky backups only to find out I needed one and it failed. I honestly wish there were a comparable open source backup system. I have yet to find anything that works as well.
I was reading about it and I actually like a lot this solution’s principle. It reminds me a lot of puppet which I have seen before (for other kind of tasks) to orchestrate several computers. Big shame it works on windows though, since I have a server with docker on ubuntu server at this point and was not really looking forward to change that. But thanks for the suggestion, is for sure very interesting
Another vote for Veeam. I use it at home and professionally. It’s a solid product and has saved my ass countless times.
REAR Relax-and-Recover will do entire system point-in-time snapshot backups to a bootable iso or physical USB thumb drive: https://relax-and-recover.org/rear-user-guide/index.html
I use rear for backing up my root, and Borg for packing up user data (for versioning, file recovery), but you can use rear for the entire system too.
Not the intended usecase but fogproject can be used to pull images. Then later you can just PXE boot and place a image back on to a differen system.
Still i think borg would be better for actual backups.
Had to search for a while what even pxe boot is, but I believe I came around the suggestion. I like fogproject main idea, sounds like a way to deploy thin clients or similar. Not exactly what I am looking for,but it’s good to know this exists. Thanks!
What can also be a good option is urbackup. it supports different operating systems full image backups of windows clients. Not entirely sure if it supports image backups of a linux clients how ever.
Maybe btrfs with RAID 1?
