Windows Server 2008 R2 backup (wbadmin)

It’s a long time since I dont’ write… Many things happened and many more coming..

This is just a small note to remember a couple of interesting links related to Windows Server 2008 R2 backup utility (wbadmin) troubles you may have. This blog article is a good starting point for having an idea on the problem.

If you try to backup your data to a network location hosted on a Linux-based system (but I think this problem can be found also elsewhere), wbadmin could fail with the following error:

The requested operation could not be completed
due to a file system limitation.

This happens only if you try to backup only some directories and not the entire disk(s) you have. Why this problem? This is related in how Linux manage sparse files, required for such a backup. This link explains the problem in details and a way to solve it, supposing you can modify Samba configuration on target machine. If you cannot modify your configuration, you have to backup the entire disk instead of single directories.

More information on sparse files can be found in the documentation of fsutil command.
