Recovery Points - How To

Configure Recovery Points

Required Capability: Capabilities and Permitted Actions

Before you begin

wedgeTo configure Recovery Points:

  1. From the CommCell Browser, right-click a Replication Set and select Properties.

  2. In the Replication Set Properties (Replication Options) tab, select Allow Recovery Points.

  3. In the Maximum Number of Recovery Points field, specify the maximum number to retain.

    Note

    Ensure that the destination volume specified for each Replication Pair has sufficient space for the maximum number of snapshots that will be created and retained.

  4. On Windows you can configure to automatically mount the snapshots from the latest Recovery Point when they are created. (This is not available for ONTAP Snapshots.) On UNIX, you can configure to automatically mount every snapshot by default, and automatically create a symbolic link to the mount points it creates.

  5. Perform the following steps to mount the snapshot:

    Select the Auto-Mount snapshots after Recovery Point Creation option, then click Enter Mount Points.

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

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

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

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

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

    Note

    Even though 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.

  6. For Windows, select a Snap Engine Type.

    For UNIX, CDR software automatically recognizes the File Systems configured on the destination computer and detects the appropriate snap engine. For more information on supported snap engines, see Snapshot Engines - Support.

  7. In the Pre/Post Process tab, specify any Pre/Post Recovery Point commands to be run. Refer to Configure Pre-processes and Post-processes.

  8. If you will be backing up Recovery Points, see Configure CDR for Backups of Recovery Points.

  9. Click OK to save your changes.

Note

It is recommended that you also see Configuring Space Check for ContinuousDataReplicator Agents and Configuring Alerts for Low Disk Space to provide warning that the destination computer, and the cache volume in particular, is running out of disk space, which will ultimately cause all recovery points to be deleted.

You can now Create a Recovery Point.

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.

    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.

  5. Click OK.
