I have had little issues restoring from BE 2010 till today. I have one tape that I archived a bunch of data. When I go to restore I get the "you need to catalog this tape" etc message.
I went through the rebuild catalog scenario. i.e. shut off BE, rename catalog folder, start BE
and change options to uncheck "user storage media catalogs". The Catalog ran successfully said it found 300 GB of files (good)
Then I went to do the restore and it says the tape is blank.
So WTF and HUH... I have a log saying it found 300 gb or so of files. I'm running the catalog again but this tape doesn't throw errors, appears good but I don't know what else to do.
