[dietmar]

Never saw that before. Please can you post the backup log? Can you reproduce that bug when making a new backup of another VM?

i have not test another vm to backup .

 

[dietmar]

the backup log was so long ,

Obviously there went something wrong during backup. Maybe snapshot run out of space. Try to increase 'size' parameter in /etc/vzdump.conf

 

[naja7host]

is set to 2048 .

is possible to force the restore even if the file is not complete ?

You can manually restore files using 'tar' command directly.

 

[naja7host]

i have made it .
now if i start the vps i get this error

Unable to start init, probably incorrect template
Container start failed
Stopping container ...
Container was stopped
Container is unmounted

when i want to test /sbin/init

#chroot /vz/private/102/ /sbin/init
chroot: cannot run command `/sbin/init': Accessing a corrupted shared library

the private directry exist and conf file exist , i use the centos template .

i have made some test .

i have created a new vps with the same template , tested it , is working .
if i copied the backup files i get the same error .

so wich folder that i need to copies and wich one should i exlclude .

there are some damaged file but i don't wich folder is !

 

[dietmar]

there are some damaged file but i don't wich folder is !

You can see the list of damaged file in the backup log.
