Typically you set up your initial snapshot schedules with the Quick Recovery Configuration Wizard.
However, later, you may want to schedule an additional snapshot. For example, you configured a daily snapshot for Quick Recovery use and now want to add a weekly snapshot on a different disk for backup use.
You can use the VSS Exchange Snapshot Scheduler Wizard to add a snapshot schedule for a selected mailbox database.
Like the Quick Recovery Configuration Wizard, the scheduler wizard enables you to automate the refreshing of snapshots according to the schedule that you define.
However, unlike the Quick Recovery Configuration Wizard, the VSS Exchange Snapshot Scheduler Wizard does not prepare snapshot mirrors. You must use the Prepare command to prepare the snapshot mirrors before running the VSS Exchange Snapshot Scheduler Wizard.
Also, the scheduler wizard can schedule only one snapshot set for one mailbox database at a time.
At times you may want to create a one-time snapshot set. You can do so using either the vxsnap command line utility or from the VEA console using the VSS Exchange Snapshot and Snapback wizards.
