Uncompressing online indexes

When you try to browse or restore data from savesets with compressed indexes, the indexes are automatically de-compressed to a temporary directory. You can also use the Manage Backup Indexes page to manually de‑compress the indexes for one or more backups.

The temporary directory is deleted after the operation completes.

To manually uncompress online indexes:
1
In the Navigation pane, click Create Restore Job, and then on the Choose Saveset page, click Manage Indexes.
2
Click Choose Client, and select the client for which the backup was created.
-OR-
To quickly locate the client (s), you can use the Search box at the upper right corner of the table. The data in the table is filtered as you type the search text into the box.Click OK to close the dialog box.
3
Optionally, click Choose Plugin, and select the plug-in that was used to create the backup. Click OK to close the dialog box.
4
Click the View icon to list the savesets for the selected client and plug-in.
5
In the savesets list, all items are selected by default.
To de-compress indexes for specific savesets, clear the check marks for the savesets that you want to exclude. Alternatively, click the check box in the header row to remove all check marks, and select the individual savesets.
6
Click Uncompress.

Managing Snapshots

Explore snapshots is a feature that allows you to view, mount, and unmount the existing snapshots.

Explore snapshot feature is currently supported for Dell Storage Manager and Huawei OceanStor Manager. To add these storage manager’s refer Managing the Snapshot Array Manager. Currently, NetVault Backup Plug-in for FileSystem supports snapshot-based backups.

You can perform following operations:

•
Restoring snapshots
•
Setting expiry for Snapshots
•
Mounting Snapshots
•
Unmounting Snapshots

Restoring snapshots

Restoring data from a snapshot involves a simple copy operation from the snapshot directory to the target/secondary system. The restore operation overwrites the existing volume configuration. Any changes that are made to the data in the volume after the Snapshot copy is created, are lost.

To restore snapshots refer, Creating restore jobs.

Setting expiry for Snapshots

Each snapshot has an expiration date and time, you can preserve a snapshot to prevent it from expiring. Snapshot expires when the backup Saveset expires, even if the snapshot expiry date is greater than Saveset Expiry date. However, if this snapshot is already mounted, the snapshot goes in the pending state if the saveset has expired.

To set an expiry date of snapshot
1
In the navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select the SaveSet Name and then click Explore Snapshots.
3
Select the snapshot from the Saveset Name list and click Set Expiry.
4
Select Change Expiry Date, and choose the options to set the expiry date and click Ok.
a
On: Set the date from the calendar and set the time
b
Now: Snapshot expires Immediately.
c
Expire with Saveset: Snapshot never expires.
* 
NOTE: In case of Huawei OceanStor Device Manager, you can only set an option to expire snapshot immediately.
In the Explore Snapshot page, the Expires column updates the date and time.
