Dell POWERVAULT MD3600I - Manual (Page 121)

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.
The snapshot image creation operation completes as soon as the synchronization operation is complete. To cancel the
pending snapshot image creation before the synchronization operation completes, do the following:
1. From the AMW, select either the snapshot group or consistency group that contains the pending snapshot image.
2. Do one of the following:
– Copy Services → Snapshot Group → Advanced → Cancel Pending Snapshot Image.
– Copy Services → Consistency Group → Advanced → Cancel Pending Consistency Group Snapshot Image.
The Schedule Settings window is displayed.
3. Do one of the following:
– If you want to use an existing schedule, click Import settings from existing schedule. The Import Schedule
is displayed. Select the schedule you want to import from the Existing schedules table and then click
Import.
– If you want to create a new schedule, define the settings appropriately for the schedule. For more
information on the settings, see the online help topics.
4. If you are creating the schedule for a snapshot group, select Create the First Snapshot Image Now to create a copy
of the associated base virtual disk at the same time the schedule is created.
5. If you are creating the schedule for a consistency group, click Enable snapshot image scheduling to enable the
scheduled snapshot image creation for the group.
6. Click Finish to create the schedule for the snapshot group or consistency group you selected.
The system performs the following:
– Creates the schedule for the snapshot group or consistency group and updates the Properties pane for the
snapshot group or consistency group.
– If you had selected Create the First Snapshot Image Now, the system takes a copy of the associated base
virtual disk. Each subsequent snapshot image capture depends on the schedule you created.
Editing A Snapshot Schedule
Use the Edit Snapshot Image Schedule option to modify the schedule settings defined for a snapshot group or
consistency group. You can also use the Edit Snapshot Image Schedule option to temporarily suspend scheduled
