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 :
-rwxr-x--- 1 urbackup urbackup 80G juin 21 18:56 Image_C_160621-1822.raw
-rwxr-x--- 1 urbackup urbackup 2,5M juin 21 18:56 Image_C_160621-1822.raw.bitmap

-rwxr-x--- 1 urbackup urbackup 577 juin 21 18:22 Image_SYSVOL_160621-1822.raw.mbr
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 ?
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.
