Unexposing a snapshot

After restoring from a snapshot, you may choose to unexpose a snapshot; unexposing a snapshot

completely removes access to it. Note that unexposing a

Latest data

will result in that snapshot also

being removed.

NOTE:

A snapshot of a shared folder cannot be exposed or unexposed using ASM. Use the Shadow Copy Client

to view snapshots of shared folders from a client computer. Snapshots of a shared folder are stored on the

same logical disk as the shared folder, in a protected system folder.

To unexpose a snapshot:

Select an Exchange storage group, SQL Server database, or user-defined application in the

content pane.

In the Actions pane, click

Snapshots

and then click

Manage Snapshots

. The

Manage Snapshots

dialog box displays.

Select an exposed snapshot from the snapshot list.

Click

Reverting data to snapshots

ASM allows you to revert data stored on your HP All-in-One Storage System to a snapshot. This

overwrites the existing data and reverts it to a past state.

NOTE:

•

Snapshots of shared folders cannot be reverted using ASM. To revert a shared folder to a past snapshot,

use the Shadow Copy Client.

•

Snapshots of user-defined applications that are configured as local storage only applications cannot

be reverted using ASM because all data that is on the same volume as the application would also be

reverted.

Select an Exchange storage group, SQL Server database, or user-defined application in the

content pane.
