Win2008 Tapes on Win2012R2
Can a tape back up done on a Windows 2008R2 Networker server be restored/recovered through a Win2012R2 Networker server?
I have read in this forum that the OS on the recovery server must be the same as the one used during backup. However, I'm not sure if that means platform level (as in Windows to Windows) or edition level (as in Win2008R2 to Win2008R2).

Hi,
It does not matter. Only compatibility that needs to be thought of is the Tape Drive/Tape Generation. You can only read 2 generations back. i.e. LTO -5 tape drive can read LTO-3 tapes.
Only thing to keep in mind is the block size, it should be same on all OS. By Default it is 64KB, unless you change it from registry.

It would only matter for system-specific files of course. Otherwise - no issue.

There's no issue with changing the OS of your NetWorker server (but best to do an mmrecov on the latest bootstrap rather than trying to copy files over between them - holey files handled differently by different filesystems and all that).
For client restores, there's generally no issue recovering files from NetWorker backups to a different client OS. The main issue is the differences in file metadata that can exist. However, NDMP backups are entirely different. NetWorker has a standard format for writing files to media. NDMP is a Data Management Protocol standard which allows the filer that's backing up to send data to media in its own format. That format isn't specified in the standard, and varies between filers. As such, a NetApp NDMP backup should only ever be recovered to another NetApp (preferably using the same NDMP options and version), a Celerra backup to another Celerra, etc.
