Re: [Veritas-bu] De-multiplexing

All backup images made under previous NBU versions are forward compatible with newer versions.

I see only two choices:
1) Expire the data on the tapes that your customers are asking to be disposed of and do nothing more.
2) Call back all the tapes and duplicate each customer's backups to individual tapes, keeping all backups single-tenant. Destroying all the old tapes and any new ones going forward will satisfy their requirement.

Option 1 is obviously more feasible (potentially the only realistically possible solution if there are thousands of tapes), but depending on what your contractual obligation of 'disposed of' means, you may have to go with option 2, or someone may face making a tough decision. This might be a good opportunity to revisit your contracts and defining multi-tenancy on tape (and even disk for that matter), what your company will/won't do, and allowing the option of single-tenancy for a higher price. I would recommend trying to think about this and not word it so it locks you in to specific media or technologies.

Good luck!

Hi-

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.

Thanks You-
