Before You Begin

Perform a backup operation.

Procedure

2. Click an instance name.

   The selected instance page appears.

3. In the Restore column of the data center, click Restore.

   The Backup content page appears.

4. Select the check boxes for the keyspaces that you want to restore, and then click Restore.

   The Restore dialog box appears.

   Note

5. Complete one of the following tasks depending on the type of restore operation you are running:

   • To perform an out-of-place restore operation, select the Out of place tab, and then select destination instance for the restore operation.

   • For an in-place restore operation, the destination instance remains the same as the source instance.

6. To have the software invoke the sstableloader to stream data across the cluster nodes, select the Use SSTableLoader tool check box.

   Select a staging path that has enough free space to hold the sstables for the keyspaces that you want to restore.

   Note

   It is mandatory to select the Use SSTableLoader tool check box while performing an out-of-place restore operation.
