@henri9813 yes thank you for correcting my message

I confirm that this is the current behaviour, as @pilow reported here https://xcp-ng.org/forum/post/99446 We might change it in the future to make it better, but it won't be trivial to change.

@MajorP93 aha, yea. Per disk concurrency is important too.

@Forza Cancelling a backup run is also on our roadmap ,as soon as we have done reworking the tasks to use xo-task on the full chain, and not an hybrid of various iteration of the tasks objects better tracking of the backup run is also on our roadmap , this is also linked to the task changes plus are some issues with the size on the remote before being able to do this In any case, both are on our backlog

There are no other jobs. I've now spun up a completely separate, fresh install of XCP-ng 8.3 to test the symptoms mentioned in the OP. Steps taken Installed XCP-ng 8.3 Text console over SSH xe host-disable xe host-evacuate (not needed yet of course since it's a brand-new install) yum update Reboot Text console over SSH again Created local ISO SR xe sr-create name-label="Local ISO" type=iso device-config:location=/opt/var/iso_repository device-config:legacy_mode=true content-type=iso cd /opt/var/iso_repository wget # ISO for Ubuntu Server xe sr-scan uuid=07dcbf24-761d-1332-9cd3-d7d67de1aa22 XO Lite New VM Booted from ISO, installed Server Text console to VM over SSH apt update/upgrade installed xe-guest-utilities Installed XO from source (ronivay script) XO Import ISO for Ubuntu Mate New VM Booted from ISO, installed Mate apt update/upgrade xe-guest-utilities New CR backup job Nightly VMs: 1 (Mate) Retention: 15 Full: every 7 Exact same behaviour. After first (full) CR job run, additional (incremental) CR job runs results in one more 'unhealthy VDI'. I've engaged in no other shenanigans. Plain vanilla XCP-ng and XO. There are only two VMs on this host, the XO from source VM, and a desktop OS VM which is the only target of the CR job. There are zero exceptions in SMlog. What do you need to see?

I will tell you a little secret, you taught me more than that one command for CLI lol One more important note for my Bitwarden Thanks again bud!

Hi @jshiells, After some tests, I don't think it can be caused by the load balancer. If the load balancer tries to migrate a VM that is being backed up, the migration instantly fails and nothing happens. Reversely, if a backup job starts when a VM is being migrated by the load balancer, the backup will fail for that VM with error "cannot backup a VM currently being migrated".

Just a quick update. I tried changing the time to see if somehow doing it at midnight was causing the issue. I also tried changing the destination for the health check to restore to in case it was some issue with the HDD. Neither were successful.

@Pilow You might be right, this may be simpler to implement than we imagined. We'll keep you informed when we progress on this.

Thanks @Pilow for the test

For completeness sake. Confirming that the fix also works in my second lab as well.

@Bastien-Nollet nice !

@florent turning off CBT removed the "fall back" message but my Delta backup is still doing full backups.

@planedrop yes
