[PVE-User] pbs prune from commandline ?

[Roland]

hello,

isn't there a commandline equivalent of  proxmox backup server side prune ?

(i.e. pbs -> Datastore -> Prune & GC -> Prune Schedule )


how can i trigger a prune from commandline on the pbs side , like i can
do gc and verify  with proxmox-backup-manager  ?

i only find prune option with proxmox-backup-client.

this should be be equivalent to:  pve -> storage -> pbs-ds -> Backup
Retention  tab, i.e. it's the prune definition on the client side.

shouldn't there exist prune option in proxmox-backup-manager, too !?

regards
roland

You can change the prune-schedule via CLI with the manager

# proxmox-backup-manager datastore update DATASTORE --prune-schedule '...'

And why exactly doesn't `proxmox-backup-client` counts as CLI?

The manager is more for server-admin commands, GC is always a datastore wide operation
not affecting any backups, so no client notices it.

Pruning, on the other hand, should be done by the client making the backups itself,
as it has a big impact on the actual backup availability.

But the client is available in all our repositories (PBS, PVE, PMG) so you can just
install it, if not already done, and use that:

# proxmox-backup-client prune vm/100/2021-03-23T12:32:02Z --keep-last 100 
--keep-daily 42 ...

If you do not want to always login you can just edit your .bashrc (or whatever your shell uses)
and setup the environment variables for your local server there.

yes, it counts. but isn't that somewhat pruning "at the remote" level,
where you need a privileged (...@pbs) user for? i find using it
complicated, too.

yes, but i'm just asking because i'd wonder if this is a "consistent"
interface - i don't use prune on the client side and don't think it's
easy to handle to iterate trough every single VM for pruning, as number
of VMs may change and you need to adjust a commandline prune/script.

i simply wonder if there isn't a commandline prune for pruning at
datastore level (like you can do gc or verify via commandline at
datastore level)
