Recover Replicated Data - How To

Automatically Mount a Recovery Point Using CDR

Before You Begin

Required Capability: See Capabilities and Permitted Actions

wedgeTo configure a Replication Set so that its Recovery Points are automatically mounted:

  1. From the CommCell Browser, right-click a Replication Set for which at least one Replication Pair has already been created, and select Properties.

  2. From the Replication Options tab of the Replication Set Properties screen, select the Auto-Mount snapshots after Recovery Point Creation option.

  3. Click Enter Mountpoints.

  4. In the Enter Mount Points dialog box, click the Mount Point column for each Destination Path and do one of the following:

    • For Windows, do one of the following for each snapshot to be mounted:

      Specify a drive letter (e.g., G:) to which the snapshot will be mounted. Ensure that you specify an unused drive letter.

      Type a mount point name (e.g., G:\mountpoint1) to which the snapshot will be mounted.

    • For UNIX, type the path to the symbolic link that points to the directory where the snapshot is mounted.

  5. Click OK.

Manually Mount or Share the Snapshots of an Existing Recovery Point

Before You Begin

Required Capability: See Capabilities and Permitted Actions

wedgeTo mount or share the snapshots of an existing Recovery Point, on Windows:

  1. In the CommCell Browser, perform a Browse operation for one of the following:

    • Replication Set

    • CDR Agent

    • Client

    • Application iDataAgent (Exchange, SQL)

  2. Do one of the following, depending on the object you browsed:

    • From the Recovery Points dialog box, select a Recovery Point and click View Snapshots.

      In the Snapshots dialog box, select a snapshot and click Mount.

    • In the Browse dialog box, right-click the snapshot to be mounted, and select Mount Snapshot.

  3. Do one of the following:

    • specify a drive letter (e.g., G:) to which to mount the Recovery Point. Ensure that you specify an unused drive letter.

    • type a mount point name (e.g., X:\mountpoint1) for the Recovery Point.

      Note

      For Windows 2003, Recovery Point snapshots created with VSS, cannot be mounted on a mount point (e.g. X:\mountpoint1), this needs to be mounted to a drive letter (e.g., G:).

  4. If you want to create a share, do one of the following, depending on which object you browsed:

    • In the Snapshots dialog box, select a mounted snapshot and click Share.

    • In the Browse dialog box, right-click the mounted snapshot to be shared, and select Create Network Share.

    In the Enter Share Name dialog box, type a name for the share and select Make share writeable option. Click OK.

  5. Close the Snapshots dialog box or Browse window.

Automatically Mount Snapshots for Fan-In Recovery Point

Before you Begin

  • Review How to Setup Fan-In Configuration

  • You can configure CDR so that the snapshots that comprise the latest Fan-In Recovery Point will be automatically mounted when it is created. This will affect all Replication Sets that use the computer as a Fan-In destination. Alternately, once Recovery Points have been created, you can select an existing Recovery Point and mount its snapshots.

Required Capability: See Capabilities and Permitted Actions

To configure CDR to automatically mount snapshots for Fan-In Recovery Points:

  1. From the CommCell Browser, right-click ContinuousDataReplicator on the destination client, and select Properties.

  2. From the Fan-In tab, select the Recovery Points tab, and select the Auto-Mount snapshots after Recovery Point Creation option.

  3. Click Enter Mountpoints.

  4. In the Enter Mount Points dialog box, click the Mount Point column for each Destination Path and specify a drive letter (e.g., G:) to which the snapshot will be mounted.

Notes

  • Ensure that you specify an unused drive letter.

  • Do not specify mount points for a UNC path. If you specify the mount point for a recovery point on a UNC path, this mount point is ignored when a recovery point is created on a UNC path.

  • When a Recovery Point snapshots created with ONTAP snap engine and Auto-Mount snapshots after Recovery Point Creation option is selected, share of snapshot will be created.

  1. Click OK.

Copyback Exchange Data from a Consistent Recovery Point

Before You Begin

  • Review Copyback

  • This procedure assumes that you used Add App to create your Replication Pairs. For more information, refer to Add a Replication Pair and Application Integration.

  • While it is possible to copy back Exchange data from the Live Copy, this data is not in a consistent state and thus application integrity is not ensured.

See Capabilities and Permitted Actions

wedgeTo Copyback Exchange data from a Consistent Recovery Point:

  1. For Outlook 2003, change the profile for any mailboxes being restored which have "Cached Mode" enabled, to DISABLE CACHED MODE. "Cached mode" can be enabled again after the Copyback operation completes successfully.

  2. Abort the Replication Pairs for the source volume to which you will copy back Exchange data. This avoids slow copyback operation on the source volume.

  3. Dismount the Exchange Stores for the Storage Group to which you will copy back point-in-time data.

  4. Delete or rename all Exchange transaction logs on the Production Exchange Server for the Storage Group being restored.

  5. In the CommCell Browser, perform a Browse operation for one of the following:

    • Replication Set

    • CDR Agent

    • Client

    • Application iDataAgent (Exchange)

  6. Do one of the following, depending on which object you browsed:

    • In the Recovery Points dialog box, select the Consistent Recovery Point(s) to be copied back, and click Copyback.

    • In the Browse dialog box, select the Consistent Recovery Point(s) to be copied back, and click Recover all Selected...

  7. In the Copyback dialog box, select a Recovery Host, the host to which the data will be copied back.

  8. Specify a Recovery Path for the data you want to copy back. The Recovery Path must be larger than the data being copied back. To assign a Recovery Path, do one of the following:

    • double-click the path listed in the Recovery Path column and type a path on the selected host

    • click the Browse 'Recovery Host' button and browse to a destination path on the selected host

  9. Select Overwrite existing data under 'Recovery Path'.

  10. Click OK to copy back the data. The system displays a progress bar as it copies back the data. You can track the progress of the recover operation from the Job Controller dialog box.

  11. Mount the Exchange Stores.

  12. For Outlook 2003, the profile for any mailbox(es) changed to DISABLE CACHED MODE can be changed back to Cached Mode. The user will be able to see the recovered data instead of the cached copy.
