@olivierlambert Thanks. I will do that. I did bump the memory up to 12GiB and the backup ran successfully but I will pursue a ticket with the 3rd party script maker as well. Thank you for your time!

@codenin Is the NAS something local or are you hosting a NAS in Azure? I guess I just got a bit confused by the mention of Azure here. Usually, with cloud providers, you want to use their services more than just directly hosting something there. So for file storage, either S3 compatible blob storage, or using one of their file share services that exposes SMB or NFS.

Your backup is a stream, doing backupressure (or not). As explained in the linked topic, it depends on dozens of different parameters. You might try to use NBD with 4 concurrent download, that might be better though, because I'm betting your bottleneck is likely XAPI export speed.

They are able, but not at a great speed. It doesn't matter how many cores, it's likely heavily single threaded and relying on how fast you can do many efficient instructions per cycle. That's why you should switch to CR.

Depending on the size of your backup repo you can copy the whole disk repo to tape with tar. So you have a desaster-backup. You can also span mutiple tapes with tar. https://www.gnu.org/software/tar/manual/html_section/Using-Multiple-Tapes.html

You shouldn't run anything other than the last commit as possible (which is de934ec609b1bfb48cd598de8b096a6b4cf1f963 now).

At a certain point, I don't know when because we are talking about a home lab here. I could attach the USB HDD same as a virtual HDD and I could put exclusions on it

Question/suggestion to @julien-f and @florent

Hi, See https://github.com/vatesfr/xen-orchestra/issues/7569 ep1p created this issue in vatesfr/xen-orchestra closed Backup of metadata is missing settings options for reporting failures. #7569

@Danp Yup. I did miss it... and you were right. Thanks!

@archw Ignore that entire post...user error. I have two networks that are spelled very close to the same thing and I was using the wrong one.

@olivierlambert Well, last night the backup completed just fine despite me taking no action. I updated the XO to the latest commit when I got in this morning so hopefully the issue I had back in June don't come back.

@rtjdamen NBD scales relatively well, yes.

Question for @florent

Hi @florent, also [NOBAK] marked disks are transfered and snapshot not removed. In Delta mode backups. Thanks!
