Recovery
This page allows system administartors to perform recovery. To enable users to access shared folder snapshots, please enable Make snapshot visible for each shared folder so that users can access the snapshots via File Station or Windows File Explorer.
Shared Folder
To restore individual files/folders in a shared folder:
- Select the shared folder you wish to restore.
- Click Recover.
- Select a snapshot version you wish to restore from.
- Click Browse, and copy the files/folders you would like to restore to the destination.
To restore a shared folder:
- Select the shared folder you wish to restore.
- Click Recover.
- Select a snapshot version you wish to restore from.
- Click Action, and select Restore in-place from the drop-down list.
- You will see a confirmation message. Click Yes to confirm the action.
To clone a snapshot to a new shared folder:
- Select the shared folder you wish to clone.
- Click Recover.
- Select a snapshot version you wish to clone to a new shared folder.
- Click Action, and select Clone with a new name from the drop-down list.
- You will be redirected to the Clone page in Control Panel > Shared Folder > Create. Enter the name of the cloned shared folder and click OK to finish.
Note:
- The shared folder "homes" cannot be restored.
- The cloned shared folders cannot be encrypted.
- If a snapshot is taken when transfer of any files is still in progress, the data consistency will not be guaranteed.
- Limitations on encrypted shared folders:
- Neither type of recovery is available for mounted encrypted shared folders.
- Clone with a new name is not available for encrypted shared folders.
- Unmounted encrypted shared folders can be restored from previously taken snapshots by using Restore in-place.
To switchover the replication of a shared folder:
- Select the replicated shared folder you wish to switchover.
- Click Switchover.
- Select the new destination server if there are multiple replication tasks of the shared folder.
- Click Switchover to start the action.
To failover a replication of shared folder:
- Select the replicated shared folder you wish to failover.
- Click Failover > Failover.
- Select the version of snapshot to restore.
- Click Failover to start the action.
Note:
- You can only initiate a failover upon failure of the source server.
To reprotect the replication of a shared folder:
When being failed over to the destination server, the replication task will stop syncing data between the two servers. You will need to reprotect the replication task after the original source server is recovered.
- Select the failed over shared folder you wish to reprotect.
- Click Failover > Reprotect.
- Select the new source server.
- Select the new destination server if there are multiple replication tasks of the shared folder.
- Click Reprotect to start the action.
Note:
- The data of the replicated shared folder existing on the the new destination server will be overwriten by that on the new source server.
- If the selected snapshot version for failover did not exist on the partner server, it may take longer time to reprotect.
To perform a test failover for a replicated shared folder:
- Select the replicated shared folder you wish to test.
- Click Test Failover > Test Failover.
- Select the Test Server if there are multiple replication tasks of the shared folder.
- Enter the Name for Test Failover of the shared folder, and select a snapshot version to test.
- Click Test Failover to start the action.
Note:
- Performing a switchover/failover of a replication will cleanup its test failover.
- You cannot create a replication task for a test failover shared folder.
To cleanup test failover for a replicated shared folder:
- Select the replicated shared folder of which you wish to clean up test failover.
- Click Test Failover > Cleanup Test Failover.
- Tick the test failover you wish to cleanup.
Note: Tick Delete test failover data if you no longer wish to keep the shared folder created for test failover.
- Click Cleanup Test Failover to start the action.

To restore an iSCSI LUN:
- Select the iSCSI LUN you wish to restore.
- Click Recover.
- Select the snapshot version you wish to restore from.
- Click Action, and select Restore in-place from the drop-down list.
- You will see a confirmation message. Click Yes to confirm the action.
To clone a snapshot to a new iSCSI LUN:
- Select the iSCSI LUN you wish to clone.
- Click Recover.
- Select the snapshot version you wish to clone to a new iSCSI LUN.
- Click Action, and select Clone with a new name from the drop-down list.
- You will be redirected to the Clone page in Storage Manager > iSCSI LUN. Enter the name of the cloned iSCSI LUN and click OK to finish.
Note:
- If a snapshot is taken when transfer of any files is still in progress, the data consistency will not be guaranteed.
To switchover the replication of a shared folder:
- Select the replicated iSCSI LUN you wish to switchover.
- Click Switchover.
- Select the new destination server if there are multiple replication tasks of the iSCSI LUN.
- Click Switchover to start the action.
To failover a replication of iSCSI LUN:
- Select the replicated iSCSI LUN you wish to failover.
- Click Failover > Failover.
- Select the version of snapshot to restore.
- Click Failover to start the action.
Note:
- You can only initiate a failover upon failure of the source server.
To reprotect the replication of a iSCSI LUN:
When being failed over to the destination server, the replication task will stop syncing data between the two servers. You will need to reprotect the replication task after the original source server is recovered.
- Select the failed over iSCSI LUN you wish to reprotect.
- Click Failover > Reprotect.
- Select the new source server.
- Select the new destination server if there are multiple replication tasks of the iSCSI LUN.
- Click Reprotect to start the action.
Note:
- The data of the replicated iSCSI LUN existing on the the new destination server will be overwriten by that on the new source server.
- If the selected snapshot version for failover did not exist on the partner server, it may take longer time to reprotect.
To perform a test failover for a replicated iSCSI LUN:
- Select the replicated iSCSI LUN you wish to test.
- Click Test Failover > Test Failover.
