XI Restore Script bug

[arnab.roy]

The restore script is broken in 2011R3.3 as someone changed the unzip command with tar and it now fails to unzip the original back up , replacing the tar with unzip gets it fixed though...

Yeah we made a change on that a while back because zip has either a 2gb or 4gb file size limit, and some people had backups that were larger than that, so we updated it to use tar instead.
