Distibuted backups doesn't clean up the deltas in the BRs

[ph7]

I have a test job where I test the distributed backup
They are both on a truenas SMB server

I have it running every 20 minutes and retension set up like this:

It's been working fine for a couple of days
But after an update (evening of 30th I think) it started to misbehave

The day before I had 8-9 Deltas to choose from, today it's a lot more.
so I upgraded to a6c50 without success

Here are the 15 oldest ones

And the 15 newest

And there are 109 of them. Shouldn't be more than max 11

And the distribution thing seems odd to me
All the snapshots on one BR and VM's on the other

But the T1-LAB-BCK-TEST2 seems a bit empty to me

This was a log one

@ph7 try to put RETENTION to 1 in the schedule, as you are using LTR parameters

@Pilow
According to earlier info, it should add schedule + LTR and has done so before
But I will try to make any change just to have it to reread the conf

[ph7]

I found an old one

The backups from 05:25 to 07:45 have been erased

[ph7]

I changed retention to 4 but no cleanup after 08:45 run
Changing to 1 and we will see at 09:05

[ph7]

Still no cleanup

@ph7 Hi,
We found the issue. It should be fixed by https://github.com/vatesfr/xen-orchestra/pull/9667
However, given the number of delta, it may take a while to merge the whole chain back to 2 backups.

fbeauchamp opened this pull request in vatesfr/xen-orchestra

open fix(backups): schedule reference is missing #9667

@pierrebrunet
I was just about to start the update of the fix_mirror_schedule when I saw Your new master update,
Running the update now

[ph7]

@pierrebrunet
That was quick, just a few seconds of garbage collection and

Changed backup retension to 5 and wait for the 15:05 run
Looks like You nailed it

[ph7]

And I was able to restore from 15:05 backup

I was running the shedule with 20 mins backup retention and it is running fine together with the LTR
And here is the manual I ran at 14:56 removed
