Backup Proxmox OS on RAID1 ZFS

[Mario Rossi]

Hi, I have a proxmox server with two small disks in raid1 ZFS created during the setup of proxmox.
On these disks there is only the operating system.

The VMs (and CTs) are on a second ZFS pool correctly backed up with VEEAM (except the CTs).

I know that to make backups of ZFS volumes you need to use file backup but I'm not sure which path to use to save everything on the disk.
For now I tried creating a job with the simple object /
It seems that inside there is all the content of the OS partition (which for MS Windows would be C:\)

The goal is that if for some reason the server does not start anymore I can:
- Install proxmox from scratch on the server
- Install the Veeam agent
- Restore the entire ZFS pool
- Restart the Proxmox server
-> Return perfectly to the situation before the failure

Hello Mario,

As you mentioned:
You can set up Veeam Agent for Linux to create file-level backup in the snapshot-less mode. This allows you to back up data that resides in ZFS file system mounted to the root file system.

By enabling the following line in the VAL's /etc/veeam/veaam.ini file, you can make VAL back up only the root (/) directory and not mounted file systems.

Code: Select all

[filelevel]
rootRecursion = false

After ini file change, just restart agent service.

And you will be able to do restore only in file level.
