Which is best in my situation - Cloning or Snapshot of the Exchange server


We use VMware and VEEAM backup. Due to some database corruption on our Windows 2008 Exchange 2007 server, I am planning to run Eseutil /P and Eseutil /D on the server during this weekend.

The total size of the Mailbox database on the exchange is 365 GB and is hosted on D: Drive and the available free space on this drive is 800GB. I am planning to take a Snapshot or Clone the Exchange server before I run these Eseutil utilities.

After running these utilities, in case the database get into a problem and if data loss occurs, I can bring up the Cloned server OR the Snapshot.

In my situation please let me know what would be the best CLONING or SNASPHOT?
Any suggesting would be great!
Thanks in advance

Snapshot should be fine (and quicker) as cloning may take a while depending on size of entire server.

Ideally take a manual backup/copy of the EDB file before working on it.

Do I need to take the snapshot after powering off the exchange server.

CLONE always never snapshot performance is worse on a snapshot!

Recommending snapshots is foo bar!
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
If you need to rollback then destroy original broken server and start CLONE

If you are doing Exchange DB actions performance will be terrible writing to a delta difference disk and then it's got to merge later

Terrible idea!

No need to power off Exchange to CLONE

If just doing mailbox migration your are ok
