Storage requirements

The hardware for your SFW snapshot solution should include sufficient storage to be able to create dynamic volumes on separate disks for the following purposes:

The system and boot volumes should reside on a separate disk (Harddisk0).

Because a snapshot set contains a split-mirror snapshot copy of each of the volumes in the database, the snapshot set requires the same amount of space as the original volumes.

You can specify one or more snapshot sets for each volume with different disk locations for each. You can create more than one snapshot volume on the same disk as long as there is sufficient space available and as long as the snapshots are of different production volumes.

Disk groups must be of a Storage Foundation 4.0 or later version. It is necessary to upgrade any disk groups created using an earlier version of Volume Manager for Windows before implementing SFW snapshot solutions. Quick Recovery snapshots are supported only on volumes belonging to an SFW dynamic disk group. They are not supported on volumes belonging to a Microsoft Disk Management Disk Group.
