Backup plan succeded, change on next day to failed

Hello,

we have a problem with a backup plan. Before and after the backup there are commands that stop services and shutdown the pc after the backup is created + validated.
Attached you find a file of the backup plan history. Everthing seems to be ok, but at the next pc startup, we get a error. Before the entry is marked as backup succeded, after booting up the client it changes to failed.

The shutdown is done 15 minutes after the backup is created and validated.

We are working with the AMS and a centralized vault.
AMS OS: Win Server 2k8 R2
Client: Win XP SP3

Detailed errors next day:
