After buying few more disks for our Thecus NAS 7700Pro I have decided to have System State backup of one of our servers.

After creating a new share, configuring backup task, I’ve encountered a following error:

The version does not support this version of the file format

After some googling, testing and changing options in smb.conf I’ve found that following solution as most simple:

  1. Create RAID filesystem of ext3 or 4 type, ZFS filesystem didn’t work in our environment
  2. After creating new RAID, create SMB share for backups
  3. Reconfigure following SMB Setting on NAS:

Windows Server Backup to NAS:

change from:

Full backup (Block-level)

to

Folder backup(File-level)

After restarting, NAS is ready to receive backups.

In addition  to above, I have created a simple batch which executes a full System State as well as all drives:

wbadmin start systemstatebackup -backupTarget:\\IP_ADDRESS\Backup_OS\ -quiet

and set it in with Task Scheduler to run once a week.

That’s all :)
