For those running Snap Manager for Exchange... do you verify the snapshots? We've been running Exchange on filer iSCSI luns for several years, dutifully verifying our snapshots and dealing with the added IO during verifies.
We're currently in process of setting up mirrors to a remote filer, with the intent of running the verifies on the remote filer. I heard in conversation, however, that verifies have fallen out of fashion. Is it that the snap process has so little error that there's no point in running verifies? Are verifies obviated when running in a DAG?
Thanks for your thoughts,
According to Microsoft you do not need to run verifies if you are running Exchange in a DAG and have at least 2 copies of the databases. The rationale behind this is because if a database detects bad pages during regular Database Background Maintenance it will retrieve these pages from the other copy of the database.
If you are only running with a single copy of a database you should continue to run verifies.

Hi Craig,
Thanks, that’s very helpful. Can you point me to a link for this requirement/decision tree? I’ve heard it repeated a couple of times now, but I haven’t found a canonical source.
Thank you, Andrew

Database verification is not a requirement for databases with at least two copies in a DAG. By default, when performing a DAG backup with SnapManager for Exchange, verification will be off. This is documented in the Exchange Best practices report (TR-4033 and TR-4221)
