Working With Received NAS Share Snapshots
The Received Snapshots page allows you to view and work with received NAS shares. When a replicated NAS share is received from a source system, it is saved as a snapshot. The snapshot contains all of the data necessary to fully failback the share to the point in time when the snapshot was saved.
Q-Cloud Protect is designed to be used as a replication target for on-site DXi appliances, on-site DXi appliances using OpenStorage (OST) optimized duplication, or Veritas NetBackup or BackupExec OST servers with DXi Accent enabled.
Q-Cloud Protect does not support use-cases for directly accessing data stored in NAS shares or VTL partitions from the cloud appliance. To access data stored in a share or partition from the cloud appliance, you must failback and recover the data at the source.
Use the Received Snapshots page to perform the following tasks:
Note: The target system will retain up to 10 replication snapshots (default setting) for each replicated partition. When 10 snapshots have been saved, the oldest snapshot is deleted to make room for each new snapshot that is received. For instructions to change the maximum number of snapshots retained for each partition, see Managing Replication Sources.
- From the Replication page, click Receive > NAS > Received Snapshots to display the Snapshots List.
- Review the following information about received snapshots:Navigation Information
- Snapshots are grouped by NAS share.
- To see all available snapshots for a share, click the plus icon [+] next to the share name.
- Click a column heading to sort the rows in the table by that column. Click the column heading again to reverse the sort order.
The name of the share.
The hostname of the system from which the snapshot was sent.
The time the most recent replication job started.
The time the most recent replication job finished.
The status of the most recent replication job. Click the status to display detailed information about the most recent replication job.
For more information, see The status of the most recent replication job. See The status of the most recent replication job. See Replication and Synchronization Status.
Perform a failback of a NAS share if a source system that was previously unavailable becomes available again.
When you failback a share, you select a received snapshot on the cloud appliance. The cloud appliance copies the snapshot back to the source system. You can then perform a recover operation to recreate the share on the source system just as it was at the point in time when the snapshot was saved.
Before you can failback a share, you must add the cloud appliance to the list of allowed replication sources on the original source system. During failback, the original target is acting as a source when it sends a snapshot to the original source.
For detailed instructions, see Managing Replication Sources.
From the Replication page, click Receive > NAS > Received Snapshots to display the Snapshots List.
- In the Snapshots List, select a snapshot and click Failback to display the Failback Target page.
(Optional) In the Failback Destination System box, type the hostname or IP address of the source system to which to failback the share.
The default destination is the original source system.
(Optional) Leave the Use Encryption check box selected to enable encryption when sending the snapshot to the destination.
Caution: Select 128-bit encryption if you are sending data to a DXi system running a software version prior to DXi 2.1 Software.
Click Apply to send the snapshot to the source system
In the source system's Snapshots List, select the snapshot that was sent during the failback operation and click Recover to display the Recovered Share Name page.
- (Optional) In the Recovered Partition Name box, type a new name for the recovered share.
The default name is the original share name.
Click Apply to recover the share on the source system.
All data stored on the share at the time the snapshot was saved is available, and the original export protocol of the share (NFS or CIFS) is retained in the recovery process.
Note: If you previously remapped your backup application to a recovered share on the target system, you must remap your backup application again to point to the source system.
Delete a snapshot if it is no longer needed. Keep in mind that after you delete a snapshot, it can no longer be used to recover or failback a NAS share.
Note: You cannot delete a snapshot if a failback operation is in progress for the snapshot. Wait for the failback operation to complete, or abort the operation. See Viewing Snapshot Failback Job Status for Shares.
Do one of the following actions:
On the target system's Snapshots List, select a snapshot and click Delete.
Note: If you delete the last snapshot for a share while replication for the share to this target is still enabled, any replicated data not yet protected by a replicated share is not deleted. To delete this data, disable replication for the share on the source system before deleting the last snapshot.
- Click Yes to confirm the action.
