Recovering a database

In the event a database needs to be recovered, you can use the snapshot or set of snapshots to restore the data.

Caution:

Data corruption can occur if the FlashSnap utility does not have exclusive access to the volumes accessed by the Snap Back command. Before running the Snap Back command when using the snapshot data as the source, close any Explorer windows, applications, consoles, or third-party system management tools that may be accessing the volumes.

Storage Foundation provides recovery support for Microsoft Exchange storage groups or individual databases within an Exchange storage group. Through SFW's vxsnap restore command or the VSS Restore wizard, the VSS hot snapshots can be used for a point-in-time recovery of the storage group or a roll-forward recovery to the point of failure of either the storage group or an individual database within it.

Refer to the Storage Foundation and High Availability Solutions Quick Recovery Solutions Guide for Microsoft Exchange for detailed procedures on using FlashSnap with Microsoft Exchange to perform hot snapshots and to implement recovery procedures.

For Microsoft SQL Server, you can use the snapshot volumes in a snapshot set to restore a corrupt database. You can restore a database to a specified point in time, the point of failure, or the point in time that the snapshot set was created (or last refreshed).

Refer to the Storage Foundation and High Availability Solutions Quick Recovery Solutions Guide for Microsoft SQL for detailed procedures on Quick Recovery in a Microsoft SQL Server environment.
