Guidelines For Creating Snapshot Schedules; Enabling And Disabling Snapshot Schedules - Dell POWERVAULT MD3620I Owner's Manual

For more information on creating snapshot virtual disk schedules, see the
following sections on creating snapshots.

Guidelines for Creating Snapshot Schedules

Certain guidelines apply when creating snapshot virtual disk schedules:
• Scheduled virtual disk snapshot operations do not occur if:
– The snapshot virtual disk is mapped
– The storage array is offline or powered off
– The snapshot virtual disk is in use as a source virtual disk during a
Virtual Disk Copy operation
– A copy operation is Pending or In progress
• Deleting a snapshot virtual disk that contains a schedule also deletes the
schedule
• Snapshot schedules are stored in the configuration database on the storage
array. The Management Station does not need to be running for scheduled
snapshot operations to occur.
• Snapshot schedules can be created when the snapshot virtual disk is
initially created or can be added to existing snapshot virtual disks.

Enabling and Disabling Snapshot Schedules

A scheduled snapshot operation can be temporarily suspended by disabling
the schedule. When a schedule is disabled, the schedule timer continues to
run but any scheduled snapshot operation do not occur.
Scheduled Snapshot Icons
Scheduled snapshots are displayed in the AMW using the following icons.
