Proxmox backups to S3 (or similar)?

[isokiero@sopuli.xyz]

The storagebox -option isn't as flexible as S3 on Heztner (it jumps from 1TB to 5TB) and thus costs a bit more for capacity I don't need in the near future, but from proxmox side of view that should be pretty foolproof option.

Proxmox backup server (at least from proxmox) is way more expensive than any raw storage option. For the external drives, I won't do that. The server has RAID setup on disks and adding another local disk wouldn't achieve anything on my situation as I need an off-site copy.

What do you mean by expensive? It's free open source software no?

PBS is free software.

The most efficient option is probably Restic inside each VM/CT, because you pick exactly what you need to backup instead of the entire OS.

If you use any kind of deduplication and or compression, the system files do not amount to any meaningful size (assuming there is no additional encryption on the VM disks). Especially when you consider the size of OPs data, 1,5TB, then the couple of GB of system binaries etc. do not really matter.

[mangopenguin@lemmy.blahaj.zone]

True, sometimes there are other files though. For example my Minecraft server I backup the world but not the web map files, since those are over 30GB and can be regenerated.

[isokiero@sopuli.xyz]

You are absolutely correct. I don't mind the few GB's worth of data for the operating system, a single video with my drone is likely more than that and it's not something you can deduplicate nor compress very well. If I really wanted I think it should be possible to squeeze the operating system at least below 2GB, but it's just not worth the effort. I just want that the memories over 20+ years I have on the thing to remain.

As a service it's not free, but apparently I've misread the proxmox website in a hurry. I'm not too familiar with their licensing, but even if I'd get a VPS and enough storage for it to run a proxmox backup server it's still more expensive than just a raw storage from somewhere.

[peregus@lemmy.world]

I use backborg for backups.
I wouldn't use a storagebox (mounted on your VPS) because you would have data and backup in the same machine (problems with crypto and with human error like: ops, I've rm -rf everything ) and with the same service provider.
I'd use Backblaze B2 or Wasabi.

[isokiero@sopuli.xyz]

Oh, no. The data is on my local server and VPS is a whole different thing. I just brought up that I already use hetzner services, so it would be convenient to stick with a single provider.

[peregus@lemmy.world]

Oh, got it. It does make sense!

[shortn0te@lemmy.ml]

I am fully backing up my Mail Server with some exclusions like /tmp etc. with restic now for over a year, including updated binaries and docker images etc. and have about 16GB of data with hourly backups for over a year.
