Why the vm is rebooted at the end of a backup?

[mgiammarco]

Hello,
I do always backup with snapshots.
I have one windows 2008 vm that, at the end of a backup, reboots.
Unfortunately it also hangs at shutdowns so I cannot backup it.
Why the backup triggers a rebot?

Thanks,
Mario

I have updated to latest version and repaired windows vm and now it reboots correctly.
But it should not reboot!
I explain better:
1) manual backup: does not reboot
2) scheduled backup: it reboots always at the end of the backup
3) I exclude it from backup: it does NOT reboot
4) other vms are not rebooted by backup

I will check again point 3 and 4 because I do not believe it.
