Hello everyone,

I have a problem with backup/restore procedure from PVE 2.2 to PVE 3.3.

On the same server I make a final backup for all VM's. I replace the old boot disk, and install a new one and after I install PVE 3.3-1 with no problems.
I mount the backup disk, and I try to restore the VM's from backup.

this is the output:

Code:

looks your backup file is damaged :-/
I make two different backups on two different hard-disk's

The strange part is if I backup GZIP, when I restore, I receive Kernel panic and PVE system is crashed.

any advice?

PS: exist a method to check if the base VM files are OK? The backup says that the procedure complete with success! That's why I'm confused! To try a backup without compression?

Dear Dietmar,

until now the RAM appear to be the main problem. I replace all memory DIMM's with only new one...and now the system create correct backups. I restore one, and now I restore the other six. If I will discover something else, I will update the post

Thank you again for your advice!
