I do neither. I define a separate node name for monthly backups, with separate policy having the retention I wish. As licensing is NOT done by the number of node names, but by processor, this should not require additional licenses. The first backup is large, but subsequent backups are much easier to take and have less impact on database size.

The question is whether backupsets or archives are the best mechanism. I am at TSM 4.2.2 os390 In my situation I have access to os390 dfhsm which means that I can generate backupsets to disk and then use os390 dfhsm to migrate to tape and also to provide a copy of the tape to protect against media failure. So this means I do not have to archive to achieve media protection. Also backupsets are a very small database overhead and you do not have to retransmit the files over the network. Against this backup sets only work at filespace level, but in this instance only very small amount of data on filespace does not require the 6 month retention. Also individual files are easier to recover from archives, but how often do need to do this? So are backupsets a no brainer here? I am interested in the recommendations of people who use both in a production environment.
