I use cumulative incremental backups instead of differentials. There are quite
a few major benefits of incremental backups and they're very simple to use, so
I don't know why anyone would avoid them:
1) Much faster backup time (e.g. seconds/minutes vs. hours/days, depending
on your system)
2) Reduced load (which translates to increased performance for end users,
batch jobs and other concurrent activity) on your database since you don't have
to do a full scan of the DB (assuming you're using a block change tracking file
(10g+))
3) Reduced load on your network to the backup system
4) Reduced storage space required on backup disks and/or tapes
5) Much faster restore time (less archive logs to restore and apply)

Brandon
