Hi Ryan,=20
The instructor is right. In my case backups are stored offsite and only
kept ~14 days. Imagine the cost associated with keeping all your
incrementals and all the tape loads, etc. associated with a restore from
a full backup that is 3 months old. That is, if you can find the tapes.
Here at Cendant we just implemented rman + netbackup, all on Windows.
The full backup over the San (not over the network) for a terabyte-sized
database went from taking nearly 20 hours to 2.5. Awesome. With that
kind of backup time, we back it up in it's entirety every night. =20

Subject: rman incremental backups vs. full backups
I believe I read somewhere that you should only take 1 full backup ever.
I can't remember where. I just took an RMAN class from Oracle. The
instructor said that she does not agree with this. If you have too many
incrementals it increases the amount of time it takes to recover.
What are some strategies that you use?=20
