Yes it have … Now it seems to be ok with the last backups.
However i’ve got another issue with the full image restoration.
I’ve tested to restore a full client image on a clean VM with exactly the same virtual hardware : HDD, CPU, RAM, NETWORK, …
Restore process is OK but when the client reboot, it goes in the WIndows repair mode systematically and VM is unable to boot properly.
OS : Windows 2008 R2 with a 100MB system reserved volume
Backup directory looks fine :
/media/backup/urbackup/SV54/160621-1822_Image_C:

I’ve tested with multiple backups sets with the same result, except with a backup set made before enabling the CBT mode on the client …
I’ve noticed that when backing up a full image with CBT mode enabled it transfers only 24 Mb / 100 Mb for the SYSVOL volume, is it normal ?
Okay i’ll made more tests because it looks very strange …
Could you tell us in which cases CBT is used ? Only incremental image backups ? File backups ? Does the CBT usage is different with a BTRFS backend storage ?
When does it become effective for full image backups and / or file backups ?
To clarify i think you should give more details in the “3.Usage” section of the CbtUserManual :
Ok, those could be incremental then. If it has the
Basing image backup on last incremental or full image backup
in the logs, they are incremental.
It already tracks the file backed up volumes, but it does not use the tracking information during backup, yet. The manual will be improved and thanks for your feedback!
Thank you very much for your explanations / clarifications !
BTW, i’ve made another full image backup (with CBT enabled) and restore it to another test VM and it works fine, strange …
How can i check the integrity of others backups which failed after restore and rebooting the restored client ?
I would first try to mount the restored volumes in Linux (e.g. from the restore cd), to see if something is wrong in general. Or boot from a Windows cd and run chkdsk on the restored disk.
Unfortunately there currently is no way to verify the restored partition against a image backup .hash file, only the .raw file itself. If you have logs from a failed restore I would be interested, of course.
