Tom,
We are currently using traditional OS level backup. Our current systems are
not 24/7 so we can afford to have a 2-hour window to just do backups. We are
in the process of implementing a new 24/7 system. Apparently the traditional
way of backup is not suitable for this new system. There are 2 choices for
me: RMAN or backup agent. I am thinking to use RMAN if it doesn't impact the
database too much and users are able to access the database as usual during
the backup time period.
Any comment?
Thanks,
-Li
