In logmode=rollforward:
A full DB backup will backup the entire database, plus anything in the log.
An incr DB backup will only backup the log.
The logutil may not drop immediately after a DB backup, if there are
in-flight transactions that have not yet completed.  The logutil will drop
further after they complete.

Hi TSM'ers


Does anyone know the difference between a full DB backup and an incremental
DB backup while running in rollforward mode?

Currently, I can't see why they are different..  A full DB backup will clear
the log in rollforward mode and any changes from that point onward are
recorded as transactions in the log. An incremental backup saves all the
changes since the last DBBAckup - why does this not then clear down the log
records that recorded those changes?

What logrecords are actually cleared by the incremental DB Backup?
