[Networker] Is the NetWorker Oracle Module necessary?

What are the advantages of using the Legato NetWorker module for Oracleversus just using the built-in archive log feature to back up the systemon-line and then use NetWorker client to backup the data from that?

Example: Suppose on the Oracle server, I have the basic NetWorker clientsoftware installed, and I create a cron job that backs up the Oraclearchive log files to some storage location (say, disk) using thebuilt-in archive log feature, and then when the copying is done it firesoff a NetWorker save process to back up that data to tape. The saveprocess would specify a particular pool dedicated for these Oraclefiles. Since a live database does not need to be shut down for thispurpose this seems to be a completely viable option. After all, the saveprocess would not attempt to back up the data files that comprise thelive database, only the ones that were written to the storage area bythe cron job - an area that wouldn't be subject to changes by users. Infact, this seems to be an advantage over the module method since youcould then use nwrecover or saveset recover to recover the desiredfiles and then use Oracle recovery commands from there. Of course, whenrecovering data, the database might have to be shut down, depending onthe situation, but likewise if using the module, right? In fact, ifusing the module you still have to use RMAN to recover it anyway; you'renot going to use nwrecover or saveset recover.

OK, what then is the NetWorker Oracle module really giving you that theabove "example" method wouldn't? Seems like just extra cost formaintenance and more configuration for the same results?

Would appreciate any advice. We're all for using the module, but fail tosee why we need to or what it's perks are. Inquiring minds want to know.


Thanks.
