To run a little further with what Rusty wrote, it appears that *any* tape you have used might contain data from the customers of interest.  Backup images have probably been expiring for years.

So if you are required to obliterate their data, not just expire it, you'll need to move everyone's current data elsewhere and then obliterate/destroy all of the tapes.  As Rusty discussed, "elsewhere" may vary on what you want to do going forward.  I suppose similar schemes could be devised for other media types.

Cheers, Wayne

For the past 10 years we have been running 5 backup policies in a hosting environment.  We host data for about 100 different clients.  We have 5 main policies: Exchange, File Shares, Databases, VMWare, and Windows.  We use multiplexing and multistreaming, so that we have a situation where we have accumulated thousands of backup tapes with the data of various customers multiplexed, or co-mingled together. 
Some of our customers would like us to dispose of their data--and others want us to keep it.
Does anyone have any ideas about how to go about resolving this dilemma?  Can we de-multiplex the data somehow?  Any help or ideas is greatly appreciated.  The verion of Netbackup has ranged from 4 to 6.5.
