RE: incremental backups

I only use cumulative incrementals, not differentials, so there is never more than one incremental to apply. This gives me a good mix of fast/small backups and fast restores and works great for me, but like everything - it depends. I run weekly L0 incrementals, nightly L1 incrementals and hourly archive logs - all straight to tape via Netbackup. I use the change tracking log so the L1 incrementals only take about 3 minutes for a 150GB database, but of course that depends on the number of blocks you change. For most systems, only a very small percentage of blocks are changed though. Another consideration is that incrementals are only available with Enterprise Edition, but I think that may have changed with 10g.  

Regards,
Brandon

I think he has a point that too long a chain of incremental backups could create a problem.
