[SOLVED] Backup node OS and config to PBS?

[Tony]

I already have a PBS configured for a cluster to backup the VMs/CTs. Can I use it to backup the node OS and cluster config? I searched the forum but didn't find any relevant post.

thanks in advance for any hint.

hi,

you can use the backup client to do a host backup [0]

passing the directories you wish to backup should work, see the example in the documentation linked below

hope this helps!

thanks; I was hoping for some easier solution but running proxmox-backup-client on the node is ok, too.

I tried proxmox-backup-client to backup a node to PBS; on a cluster with PVE 7 it didn't ask for password, but on a cluster with PVE 6 it did. Is it the expected behavior, or am I missing something? According to the pbs manual, a password prompt is to be expected.

did check your environment variables? [0]

it's possible that the password is already saved

thanks for your hint.


I checked carefully and there is no env set. Then I tried again, and this time I got a password prompt on a PVE7 node. But not the 2nd try. So it seems the password is cached for sometime.
I solved it as follows:

crontab -l
export PBS_PASSWORD_FILE=/etc/pve/priv/storage/store1.pw; proxmox-backup-client backup etc.pxar:/etc --repository pve@pbs@pbs-hostname:store1
