DB2 archives are cleaned only after 2 full db backups. It does not mean you need to run 3 full backups daily. You can run them monthly, but just I couldn't imagine how big space will be required for logs and archives. So you have to run 2 full database backups daily just to save space.

Can't you just have enough log space to let this run for three days (or does that not meet the 3 DB backup requirement?) Does anyone know why there is a requirement for 3 DB backups before the logs are reset?

I too ran into the log overflow/blew out 300GB of archtranslog space/filesystem and had to move it to a 1TB disk to hopefully prevent this from happening again, as well as performing 3-daily FULL DB backups.

I have test database 6.1.2 and I think: 1) you need additional space for DB2 archive logs. Size is the same or bigger then logs (depends on you full backup schedule); 2) you definitely need bigger space for logs. Test TSM 6.1.2 produces logs without any activity at all (5.5 never do this). I need 2-3GB in logs and archives daily without activity at all. Most possible you should plan 4 time s more space for logs and archives: 2 x Log_Size x 2 or more for archives. Grigori G.
