Home -> Community -> Mailing Lists -> Oracle-L -> RE: EMC Snapshot Technology
Tom - I can do either a cold or hot backup. It is all scripted. I
prefer cold backups. IBM did try to sell us TDP for Oracle, get this,
to open the db on the backup server to back it up using RMAN. The files
on the backup server are just that files, no need for Oracle utilities
to back them up.

Gene,
What happens when you need to perform a recovery from the Flashcopy
backup?
Is Flashcopy done while the database is open or closed?
If the database is open, then I assume that you would need to perform
an incomplete recovery?
Just curious. I am in the middle of setting up new IBM/AIX boxes, and we will using either EMC or IBM Shark disk. Flashcopy was mentioned as a possible solution for backups. But I don't like being boxed in to performing an incomplete recovery.

I don't use snapshots, but have used EMC BCV's in the past and now use
IBM's Flashcopy for backups. I backup 1TB db in ~20 mins using
Flashcopy. Then I take it off to tape, i.e. filesystems monted on a TSM
Backup server, hence no resources needed from the production server :).

We are implementing Oracle RAC on two Windows nodes, connected to an
EMC
SAN. We'll also have a failover sight.
We are using S.A.M.E. disk configuration, with only one logical
volume,
and backups/archivelogs dumping to another volume.
The SAN is an EMC Clariion CX400.
I immediately vetoed snapshots, opting for RMAN, but I'm now taking a second look.
Does anyone use the snapshot technology as a solution for full backups?
Thanks,
Jeff
