Mirror backup: No new data to upload for this vm?

Forza

I am testing the mirror backup feature. I see a message "New new data to upload for this VM" although it is clearly transfering data.

I am using XOA on stable channel.

I noticed too that both mirror backup and full backup do not actually copy all backups.

This shows the source Remote on the left and destination remote on the right. I made sure the retention setting in the mirror backup is high enough to not exclude anything, yet we are not getting everything transferred:

Se also the same for full mirror backups: https://xcp-ng.org/forum/topic/11624/mirror-of-full-backups-with-low-retention-copies-all-vms-and-then-deletes-them/

Hi @Forza,

Could you send us a screenshot of your backup job configuration so we can try to reproduce?

Forza

@Bastien-Nollet

Here is the incremental backup config. Originally we only had the remote called srv04-incremental. I have now added srv12-incremental and wanted to copy over all existing backups to the new remote. I did the same with full backups too. Now I have each backup job using both remotes.

Thanks @Forza,
I'll try on my own with a similar configuration.

@Forza

As the named are greyed-out, could you confirm that the delta backup job saves the backup to remotes srv04-incremental and srv12-incremental, and the mirror backup job copies the backups from srv12-incremental to srv04-incremental? (or at least confirm these are the same couple of remotes)

Also, could you tell me if the VM with which you got the "No new data to upload for this VM" message was backed up by your backup job "Incremental backup every 4 hours - 8 days retention"?

The delta backup job saves to srv04-incremental and srv12-incremental.
The incremental mirror job has srv04-incremental as source and srv12-incremental as destination.

The VM that showed no data to copy message was a the "Incremental backup every 4 hours - 8 days retention" backup job.

Originally I only had one remote, srv04. I created srv04-incremental and renamed srv04 to srv04-full and used the mirror backup feature to copy all delta backups to srv04-incremental (as I did not want to attempt to move the data on the NFS backend side). Then, I set up srv12-incremental and srv12-full and created mirror jobs to copy from srv04-full and srv04-incremental. Once the mirror backups were completed I switched the normal backup jobs to store backups on both backup servers.

I can set up a support connection if you want to remotely check this.
