I have to agree. Dumping the database is the way. In fact, although there are
third party utilities that will allow you to backup a live Oracle database
without stopping it, they cost a fortune, they are only licensed on an
individual machine basis, and they do not have support for AMANDA.
I backup our 24*7*365 Oracle9i database by doing an export (the Oracle equiv.
to MySQL's dump) and backing up the resulting .dmp file. In the event a
recovery is required I can then drop the schema contents and import the dump
file to restore to the latest backup.
Yes, I am backing up a live Oracle instance with AMANDA via SAMBA.
