I am checking it
Can you confirm that this a delta backup job and you are not using block. -
@florent The original backup is delta. Using NBD+CBT to a NFS storage.
Also get these frequently:
But nothing is running in parallel.
-
this error is known : this when a mirror backup start before the end of the asynchronoux cleaning of previous backup is not done
you can check the "merge backup synchronously" on the advanced setting of the first backup
-
@florent All my backups have this set! And this only happens with the new backup code, never with the old.
-
@florent Giving up on mirror backups. Switching to direct backups to remore storage.
At least until this works again as expected. -
At least I reproduce it locally , when going from a non block remote to an encrypted remote
Is your target remote encrypted ?
-
@florent Simple NFS, no encryption.
-
@manilx said in Our future backup code: test it!:
@florent Simple NFS, no encryption.
I have a potential fix here on the branch fix_backup
( https://github.com/vatesfr/xen-orchestra/pull/8635/files) -
@florent waiting for final master
-

@florent waiting for final master
this will reach master today, and probably be released in the may version of XO
-
So are we now at the point that Delta backups, Mirrors and CR backups are all working and considered stable? I have only been able to test delta backups with my home lab setup which have been working without missing a beat since the May 22nd fix for tasks not clearing. (MS-01 running XCP-NG, TrueNAS for storage)
We do use make use of CR jobs pretty extensively with the full XOA appliance for our DR site at work but because its full XOA and "production" i have not tested anything there. That said hoping for no nasty surprises with the may XO update if this is planned on being pushed to the stable XOA release!
-
@flakpyro Very good question. I really don't need the aggravation of any backup job breaking on our production site......
