SAN based Snapshots and Disaster Recovery

  • 772

I wanted to know if anyone has has any expirience of using SAN based snapshots and replication between SANs for disaster recovery. My main worries are around databases and applications like Exchange being recovered from a snapshot, has anyone tested this at all? I am looking at CDP products, but at looking at bare minimum requiresments based on snap shots.

  1. Yes, yes I have and it can work just fine but your success all comes down to what's doing the DB/file quiescing and is it talking to the SAN controllers to syncronise the two operations. We tend to use a combination of Oracle 10/11 and some of the HDS bolt-on tools but I'm happy to help you if you let me know what DB/OS/SAN etc. you have or are looking at.

  2. Advanced Copy Services (aka Flash Copy Manager) also offloads the SAN snapshot it takes to Tape.
    Is that good enough for your disaster recovery procedures ?
