Re: Oracle backups using Business Copy
Best backup method in my opinion is bring it down cold and do an OS copy. It would be faster to go directly to tape versus disk to disk as my former employer did, but either way will work.
It is possible to use Online JFS snapshots to get a cold database backup with the following methodology:
bring the database down.
set up the online JFS snapshot on a logical volume 25% the size of the data logical volume. This will hold the writes that happen during the next part of the process.
Bring the database back up.
Back up the original logical volume which will be frozen until the online JFS snapshot is shut down.

Re: Oracle backups using Business Copy
If you cannot run cold backup, I believe you will have to use RMAN.
HP is part of the OSCP program.
cf. these links

Re: Oracle backups using Business Copy
The process is easy:
1. Bring DB to hotbackup mode .. lots and lots of scripts/methods out there. This does not stop your Instance from servicing applications, it only allows for you to have a consistent copy of the datafiles ready for copying to tape, to another disk location or in your case to do a BusinessCOPy operation.
2. Do the BusinessCOPy Operation. This Operation can either present the snapshots/BCV's to the same server or to a different server. If your instance is small, then you can perhaps just do a series of dd copies to a different disk location/server or even push it out to tape via RMAN.
3. Bring DB Instance out from Hotbackup mode.
The above is true - whether you're using VxVM or LVM as volume managers.
If you're using Veritas Products -- i.e. full VxVM (with FlashSnap and Storage Checkpoints) -- then you will even have more options to backing up and protecting your DB insatnce. You will also no longer be tied up to an array vendor.

Re: Oracle backups using Business Copy
My conf. Unix environment, Data protector 5.1, HP EVA5000, DP on-line extension for Unix 5.1.
I have a question.
Can I do incremental backups of oracle database from snapshots? Or I must have data Protector version 5.5 and on-line extension for Unix v5.5?
