Error image in the HyperV GIR Backup Job (incremental) logs:
* Error: BSA [-1073741521]: Getting NBSA predecessor backup details failed.
* * BSA -1073741521: An unknown error occurred Getting NBSA predecessor backup details failed.
* Error: NST [-1073741521]: Querying predecessor backup information failed.
* Error: [c000012f] Error in NBSA API call
Hint:
One possible reason for the error:
The latest directory for this VM in the GIR Pool has no backup data, just the object.db and another file.
Visibility of the error in the GUI:
GUI-> StorageManagement-> BackupServer-> Select Diskpool.
Click to bring the single VM into focus so that the backups appear in the right pane.
The size of individual fuses are only a few KiB large.
Fix the problem:
Identification of the names of the small size GIR Pool subdirectories.
GUI-> StorageManagement-> BackupServer-> Select Diskpool.
In the right pane, select the VM and the backup, right-click "Copy Path to Clipboard".
Delete the directory with these names (including check if directory really empty).
Rename the pool.db in the GIR Pool main directory.
Open the file C: \ program files \ novastor \ datacenter \ nbksrv \ nbksrv.conf in the editor and the line
dev.rebuildPoolDbIfNotExist = true
Insert at the end of the file, then save.
Refresh of the GIR Pool via DC GUI-> Storage Management -> [context menu on GIR POOL] Refresh
