Hi @olivierlambert, No performance gain to keep the snapshot. It's more the opposite. Leaving the snapshot means it will be only removed in the next job, meaning you'll have more to coalesce. However, it's very stable, CBT tends to have some quirks from time to time, so worth trying on few VMs first. Thanks - perhaps the backup documentation could have a page that covers each of these options and the pro's / con's of enabling / disabling each of them. They seem to be newer options added as they weren't even shown in the webinar video and I couldn't find any mention of them anywhere. Also, if it's better to have this option enabled, then perhaps it could be enabled by default ? I don't think it's possible now. I can ask internally if it's something that's planned already or doable in the future Thanks - that'll be good. Either option will be good. The ability to set the 'Full Backup Interval' against the individual schedule instead of the whole backup task may be all that needs to change. I'll submit a ticket to get this feature request started. Thanks Kent.

@olivierlambert Dou! Thanks for clarifying the speed limit - I've adjust to 100MiB, which should use about 80% of my available bandwidth. Resolving the VDIs' appears to have worked as backups going now. I just have these long running tasks which have been going multiple days with no end in sight that I can't resolve. I suspect they may be related to why I can't migrate VM's between hosts now. Cheers Kent. [image: 1736362940089-screenshot-2025-01-09-at-7.59.46-am.png]

That's the right way, yes Enjoy!

Hi @olivierlambert , Okay, I made some progress today and have worked out the steps to remove, delete or add drives to a VM. Removed drive from the server attached to and also deleted the disk itself xo-cli vdi.delete id=<the id of the VDI> Removed drive from the server attached to, but didn't delete the disk! xo-cli vdb.delete id=<the id of the VBD> Added a drive to the server xo-cli vm.attachDisk vdi=<the id of the VDI> vm=<the id of VM> If was the last one that I was missing. I'm still not sure of the difference between the 'uuid' and 'id' fields, but will use the 'id' as this seems to be what the commands are wanting. Thanks Kent.

@kent You can ask for a trial so you can do it the time you need If you use XO from the sources, you will have the feature for free (but without support/updater and such)

Restarting the toolstack on AHP101 (which was the pool master) cleared the tasks. Hopefully no long term side effects
