LTO4 With Encryption on iSeries
It is clear that with the very large number of confidential records being compromised every month and of those a large number due to theft or loss of backup tapes, companies need to treat the need to encrypt backups as a "Must do now" project. The announcement from IBM that they would be the first-to-market embedded encryption in their new LTO4 tape drive appeared at first sight to offer the way forward in dealing with this continued loss of private and confidential data. This paper looks at the possible issues of using this approach and offers some alternative options. For iSeries users the IBM offering would appear to be a straightforward solution but when looking at this in detail several issues become clear.
