Scheduling Snapshot Images
MD Storage Manager allows you to schedule regular snapshot image creation to enable file recovery, and
scheduled backups. You can create a schedule for an existing snapshot group or consistency group or
when you initially create a snapshot group or consistency group.
• You can set up a schedule for a snapshot group to automatically create a snapshot image at a specific
time in the future or on a regular basis.
• You can set up a schedule for a consistency group to automatically create a snapshot image of each
member virtual disk in the group at a specific time in the future or on a regular basis.
You can create a schedule that runs daily or weekly in which you select specific days of the week (Sunday
through Saturday). To make scheduling easier, you can import an existing schedule for a snapshot group
or consistency group. In addition, you can temporarily suspend scheduled snapshot image creation by
disabling the schedule. When a schedule is disabled, the scheduled snapshot image creations do not
occur.
Creating A Snapshot Schedule
The MD Storage Manager allows you to schedule regular snapshot image creation to enable file recovery,
and scheduled backups. You can create a schedule when you initially create a snapshot group or
consistency group, or you can add one later to an existing snapshot group or consistency group. After
you create a snapshot image schedule, you can modify these and other schedule settings.
The following guidelines apply:
• Using a schedule can result in a large number of snapshot images, so be sure that you have sufficient
repository capacity.
• Each snapshot group or consistency group can have only one schedule.
• Scheduled snapshot image creations do not occur when the storage array is offline or turned off.
• If you delete a snapshot group or consistency group that has a schedule, the schedule is also deleted.
