EMC BCV volumes and OMNIBACK

Jump to solution
We are about to install a new EMC 8000 with their "TimeFinder" software to quicken our mirroring process through BCV's. We have Omniback 3.5 and are wanting to use it to back up to tape the mirrored BCV volumes. How can we do this? Are the BCV's mountable like a LV? What is the Omniback EMC module/license used for? Thanks for your help.

Bobby,
One of our Oracle implementations uses file systems - no raw disk. So we have a separate backup system that is connected to the BCV volumes. To use the BCV's we developed text files that map the BCV's to their primary counter-parts (look at the EMC inq command). Our scripts read these text configuration files, run the EMC supplied commands that attatch (bind), sync, and split the BCV volumes, fsck the filesystems, and mount them on the backup server. Then Omniback is kicked off to perform straight filesystem backups - no Omniback/Oracle interfacing is used here. Of course, if your using raw Oracle volumes, then you will most likely need the Omniback/Oracle license.
If you can focus your eyes far and straight enough ahead of yourself, you can see the back of your head.

Yes you can split the BCV's and then mount them as logical volumes. This can be handy in that if you have a database on it you could do a cold backup with only about 5 seconds downtime.

The OmniBack/EMC integration does most of the job for you. If you want to backup an Oracle DB you'd need to buy the Omniback/Oracle integration too.

All OmniBack does can be scripted to if you're handy. I tried both but I'd go with the integration. You would have to do some scripting anyway and talk to HP Support.

Read first the OB integration PDFs. Yo'll get a good understanding of the entire process.

Time finder is very good tool for taking backup of production database without disturbing user access. U can mount LV on different host. it can not be mounted on same because after syncrnisation u will have exact copy of your volume group will be there on BCV. so u can assign BCV disk to another host and after split u can do vgimport and mount the LV.
If u have Oracle database u have to put oracle in backup mode before split and the mount those VG in different and take backup.

Jst split the BCV and mount it on the OB cell manager in a pre-exec command. Take the filesystem backup of your BCV and umount / establish the BCV again in the post-exec command.

An easy integration process.

Kurt
