Unanswered: Level 0 backup instead of Level 1 backup.
We are using IDS 7.31 and TSM 5.2.
In the bar_act.log the following WARNING is given : "WARNING: psapload does not have a level 0 backup", when I try to take a level 1 backup! The result is that a level 0 backup is taken, and not a level 1 backup.
It looks like after a level 1 backup , the next backup has to be a level 0 backup, but I thought it was possible to have several level 1 backups one after the other.
Can someone explain ?
1. Between the Monday and Tuesday backup something is run which removes entries from one of the "bar_" tables in sysutils. You can dump the contents after the monday night L1 and before the Tuesday L1 if someone doesn't "fess" up. This is what onbar uses to determine if it's got a clean L0.
2. Someone is makeing structural changes to physical or logical logs (add, changing sizes, or moving)
3. Someone is changing logging mode on a database.
You have a 24 hour window to hunt down and kill the offender. Check crons (root, informix). Good hunting.
