Hi,

using Backup Server 2.2-1

This is the sync-job:

proxmox-backup-manager sync-job list
┌─────────────────┬───────────────────────────────┬───────────────┬─────────────────┬──────────┬──────────────┬─────────┬─────────┐

└─────────────────┴───────────────────────────────┴───────────────┴─────────────────┴──────────┴──────────────┴─────────┴─────────┘

When i am executing the job it says:

2022-10-14T18:23:57+02:00: Starting datastore sync job 'backup01-fra2:mc1-fra1-z40000:backup01-fra1-mc1-fra1-z40000::s-03e28156-35a3'

cat /etc/proxmox-backup/sync.cfg
sync: s-03e28156-35a3
    ns
    owner root@pam
    remote backup01-fra2
    remote-ns
    remote-store mc1-fra1-z40000
    remove-vanished true
    schedule hourly
    store backup01-fra1-mc1-fra1-z40000

Local Owner is root@pam ( should have enough rights for what ever i guess )
Source Remote user has this rights:

Datastore.Backup on /datastore/mc1-fra1-z40000
and
Remote.Audit, Remote.Modify, Remote.Read on /remote

Just for testing i gave the Source Remote user Admin rights on /

So i guess its not a permission problem here. And if so, would be nice if the software could tell so....

------------

The general goal is to simply mirror all backups from the source datastore to the local datastore.

Any help is highly appriciated. Thank you!

just to rule out permission issues, can you post the following file from the source (the remote) ?

/etc/proxmox-backup/acl.cfg

?

what happens when you try to list the snapshots via cli on the target pbs with

proxmox-backup-client snapshot list --repository <repository>

? (see https://pbs.proxmox.com/docs/backup-client.html for details how the repository should look like)

I had a similar issue, but I resolved it by using the same account as the one that is making the backups. For me, the problem was that the new user did not have ownership of the created backup. I wonder if there is a way to make it work, without giving a user too many rights (such as Admin on \)

Same here

Password for "root@pam": ****************

I think i found the pb when understanding the "pull" fonction

root@pbs1:~# proxmox-backup-manager pull pbs2 copy_px1 backup_px
pull datastore 'backup_px' from 'pbs8999/copy_px1'
----
Syncing datastore 'copy_px1', root namespace into datastore 'backup_px', root namespace
found 0 groups to sync
Finished syncing namespace , current progress: 0 groups, 0 snapshots
pull datastore 'backup_pxadm2' end
TASK OK

I have to pull backups from pbs1.. so I must configure remote in the other way..
