Deleting A Snapshot Image
Use the Delete Snapshot Image option to delete the oldest snapshot image from a snapshot group or consistency group.
After a snapshot image is deleted from a snapshot group, the system performs the following actions:
• Deletes the snapshot image from the storage array.
• Releases the repository’s reserve space for reuse within the snapshot group.
• Disables all the associated snapshot virtual disks that exist for the deleted snapshot image.
For a consistency group you can delete:
• A single snapshot image.
• Multiple snapshot images that have the same sequence number and creation timestamp.
When a snapshot image(s) is deleted from a consistency group, the system performs the following actions:
• Deletes the snapshot image from the storage array.
• Releases the repository’s reserve space for reuse within the consistency group.
• Moves any member virtual disk, associated with the deleted snapshot image(s), to a Stopped state.
• Disables the member snapshot virtual disks associated with the deleted snapshot image(s).
To delete the snapshot image, do the following:
1. From the AMW, select the Storage & Copy Services tab.
2. Select the snapshot image that you want to delete from the snapshot group or consistency group and then select
one of the following menu paths to delete the snapshot image:
– Copy Services
→
Snapshot Image
→
Delete.
– Copy Services
→
Consistency Group
→
Consistency Group Snapshot Image
→
Delete.
The Confirm Delete window is displayed.
3. Type
yes
in the text box and then click Delete to delete the snapshot image.
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.
