    Thanks for the information. @Chico008, does the information at https://xcp-ng.org/blog/2025/10/30/xcp-ng-8-3-varstored-update-unbootable-vm-risk-and-remediation/ resolve the issue for you?

    @Bastien-Nollet said in Full backup - new long-retention options: Yes, a backup is kept if it matches one of the retention criteria, either the schedule's retention or the LTR. (the backup is not duplicated, we just check for both criteria to know if we should keep the backup or not) Could we have an option to choose wich LTR day from month to keep ? and even for weekly, what weekday ?

    It's more work, but... you have to stop the VM and export them, delete the current SR (Local Storage), recreate SR (Local Storage) as local ext4 format import the VM back In this way you switch from LVM to ext4 and the space it needs will be small, not double the space

    https://xcp-ng.org/docs/troubleshooting.html is a good start to read. In your case, it's likely inside /var/log/SMlog

    @olivierlambert Yes, i will update and have a look if it changes the behaviour anyhow. "For the rest, it's hard to answer without digging more." That`t exactly was i was looking for: Any Information where i can dig deeper? I`m looking for logs or traces of errors or so. It is not that i just wan`t this particular problem to be solved In my limited understanding of interal processes i think somehow a backup process dies and xo-server does not report or recognize this. But shouldn`t it somehow?

    @olivierlambert Oh nice, hope it's not too cold over there. It's 9AM over here in Maryland and a bit nippy but not too cold. Nope, no host or pool logs available (both are empty). Then again, I cleared all the alerts from the dashboard earlier this morning, so not sure if that's what wiped all the logs. I'm not too worried, as this is a testing environment so I'm using this host to do a lot of learning.

    @Gheppy I am not an expert on the network part but I can help on the NBD part We added some info in this PR https://github.com/vatesfr/xen-orchestra/pull/6596, it should be merged in this form or another in master in a few days. It will give the user more info on the NBD usage and the cause (misconfiguration, or network error) Then if XO ( or the proxy) can't connect to the host through the NBD (for example with a network filtering/ routing), it will fall back to the reliable (but non parallelizable) api call Finally , the backup done with NBD or the legacy api call will produce exactly the same data so they are compatibles, but using the same target (as in the same directory , same remote and same VMs) for multiple job can lead to complex support tickets with interesting race conditions. I would advise to only use the same remote/directory only if the backups jobs does not concern the same VMs fbeauchamp opened this pull request in vatesfr/xen-orchestra closed feat(@xen-orchestra/backups): more information on nbd backups #6596

    @cdbessig that's strange Since S3 remote are only able to store blocks, the option is enforced on save ( without any uI) I tested locally and the options seems to be there. Can you show me a screenshot of the backup job configuration ?

    @trent234 Interesting, good to know. I do know that XCP-ng only officially supports 7 network interfaces, so not really surprised by that. It supports more VHDs though so feel like I shouldn't be seeing this error.

    @tuxen No GPUs were removed. only 2 were added. The only PCIE item removed was a NIC but I didn't remove it from dom0 or assign it to any VMs, it was just in the system.

    I believe this is a known issue (https://github.com/vatesfr/xen-orchestra/issues/5973) that is unlikely to be fixed in XO5. We'll need to wait for @pdonias to be back from holidays to have more info on this. just-333 created this issue in vatesfr/xen-orchestra closed Error on vm.set from Jobs tab in XO web GUI #5973

    @sumansaha In summary , I've deleted Orphan VDIs from Dashboard->health . But in deletion, I've maintained the sequence of their age.It has taken 6 hours, though that depends on the VM size.

    You can't delete a base copy. You need to understand how it works before doing dangerous operations. A base copy exists if there's a snapshot. If you have 0 snap and still base copy, it could be either: because the coalesce isn't finished because the coalesce doesn't work In both case, you have to take a look at your SMlog. If you have no idea about it, you should either get pro support or start to read the doc in more details You can start here: https://xcp-ng.org/docs/storage.html#coalesce
