Llarge vm fails delta backup
Good morning,
I have a problem with the backup of a really large vm.
The vm has 4 disks with the following sizes:- 200GB
- 2TB
- 1.5TB
- 1TB
The VM runs on an XCP-NG 8.2.1 with ext storage.
I am using a Xen Orchestra Community (Xen Orchestra, commit f8303, Master, commit ad8f8)
The configured backup is of type Delta to a nas as a destination.After many hours of execution, the backup fails both using nfs and smb.
At a certain point I notice that the export/inport tasks disappear but apparently it seems that the backup continues: the space occupied on the destination continues to grow and the job status remains in running.
After a few more hours the job fails.
The backup logs are as follows.
