Using LVM to snapshot Oracle

["Mitchell Christensen" <mchristensen@packetmotion.com>]

Hey,

 

I was wondering about the feasibility of using the LVM snapshot facility to backup/restore Oracle.  Does this make sense?

 

A few issues that I am concerned about are,

• Would it be any better/faster/cheaper than RMAN (the standard Oracle backup facility)?
• Would hot-backups be possible, or would the database need to be in a quiescent state?
• Is anyone else out there doing this (or anything similar)?
• Is it reasonable to expect that I could simply take a snapshot of all Oracle related files and be able to restore a viable Oracle instance from that snapshot?

Any feedback and/or advice would be greatly appreciated.

 

-Mitch
