Tailoring Cost-effective Backup Tape Sampling Procedure


The General Counsel for our client discovered that her IT department had been recording complete system backups as a normal business practice.

For the date range of this matter, the client identified as potentially responsive a total of some 11,000 backup tapes, worth an estimated $1.1M in raw tape media alone.

Control Discovery worked with two tape restoration partners to illustrate how many months it would take and how much it would cost ($9M) to restore the entire 11,000 tapes.

We then suggested that the client advocate the use of a tape sampling protocol.

By backing up 'everything, each time', rather than simply capturing the incremental changes since each prior backup, the client had archived a substantially higher volume of duplicative data than would be expected with more common 'incremental' backup strategies.

The parties subsequently agreed to a tape sampling protocol.

Sampling the tapes resulted in the capture of virtually all of the relevant data, much more quickly, and at a much lower cost than originally forecast.
