Error when start a Sync Jobs between Proxmox Backup Server and Remote Proxmox Backup Server

[lago]

Hello,

i have a problem to start a sync job between pbs and remote pbs. I setup a job, but when start the job i have a following message:

2022-06-03T12:26:00+02:00: Starting datastore sync job 'tpbs.devsrv.comosoft.de:Storage1:Backup2:s-7010d248-ada3'
2022-06-03T12:26:00+02:00: sync datastore 'Backup2' from 'tpbs.devsrv.comosoft.de/Storage1'
2022-06-03T12:26:00+02:00: found 0 groups to sync (out of 0 total)
2022-06-03T12:26:00+02:00: sync job 'tpbs.devsrv.comosoft.de:Storage1:Backup2:s-7010d248-ada3' end
2022-06-03T12:26:00+02:00: TASK OK
This are setting for sync job

This are settings for Group filter:



What is wrong configure and what i need to change to start sync job between both pbs?
The user bkuser on remote pbs has admin rights:


Thank you and best regards

is the remote entry configured using the bkuser@pbs user?

 

[lago]

Yes, the same user - bkuser@pbs

 

[fabian]

I didn't mean whether the user exists - but whether the remote entry you are using in the sync job is configured using this user..

 

[lago]

On remote server i added a user rbckuser who is DatastoreAdmin (all rights)


On local Server i use same user to sync job to remote server

see the docs:
https://pbs.proxmox.com/docs/managing-remotes.html#sync-jobs
for a sync job, you always have two users (or tokens) involved:

• at the remote side (the source that gets pulled from), remote_user@foo
• this user needs to be able to access the backups that should be synced (so at least Datastore.Backup + ownership, or higher privileges if you want to sync more than owned backups)
• this remote user needs to be setup with a remote.cfg entry at the local side
• at the local side (the target that gets synced to), you have a local_user@bar which owns the sync job (and the synced backup groups)
• this local user needs access to the remote entry (to allow accessing the remote PBS as 'remote_user@foo')
• this local user also needs access to the local target datastore (to write groups/snapshots/chunks - at least Datastore.Backup, possibly more depending on the exact configuration of the sync job)

based on your output, your remote.cfg entry is using a user or token that has access to the remote (source) datastore, but not to any backup groups there (or there aren't any).

I found why i receive this message and how "fix" this.
First i presented remote proxmox backup server as Storage in Proxmox Cluster Datastore.
Then i have been make a backup of some VM to remote proxmox backup server.
Then I can start the sync task because I already have a group of VMs.

Thank you Fabian.
Have a nice weekend.
