I'm trying to lunch ntbackup on shutdown but the backup file (.bkf) is only 1.1 GB instead of 2.2 GB. When i try to restore using this file ntbackup tells me that it is corrupted. If i run the same command as bat file it works (the command is: ntbackup backup C:\ systemstate /m normal /f "X:\Backup_20-12-2010.bkf" /j "Bckp_Data-and-System" /L:s ). The log file tells me that everything is ok. What can i do?
The solution is to set in gpedit.msc at Computer Configuration\Administrative Templates\System\Scripts the key Maximum wait time for Group Policy scripts to 0. The default time is 600 seconds (10 minutes).
