Adding a snapshot sub-policy to a Pure Storage FlashArray SLA policy

Edit online

The procedures describe how to add a snapshot sub-policy to a Pure Storage FlashArray SLA policy.

Procedure

  1. Select the source icon and define the recovery point objective to determine the minimum frequency and interval with which backups must be made. In the Frequency field select Minutes, Hourly, Daily, Weekly, or Monthly, then set the interval in the Interval field. The lowest available frequency is five minutes.
    Tip: Edits to the frequency and interval of an SLA policy apply to all associated job schedules.
  2. Click Add Snapshot. In the Options pane, set the snapshot sub-policy options.
    Keep Snapshots
    After a certain number of snapshot instances are created for a resource, older instances are purged from the storage controller. Enter the age of the snapshot instances to purge in the Days field, or the number of instances to keep in the Snapshots field.
    Snapshot Prefix Label
    Enter an optional label to identify the snapshot. This label is added as a prefix to the snapshot name created by the job.
    Tip: Snapshot labels must contain only alphanumeric characters and underscores.
    Name
    Enter an optional name to replace the default snapshot sub-policy name displayed in IBM® Storage Defender Copy Data Management. The default initial name is Snapshot0.
  3. If your Pure Storage FlashArray supports CloudSnap functionality, you can add a snapshot offload, which creates an offload copy on a S3 cloud storage target or NFS share. This option is only available after a snapshot sub-policy is added. Click Add Snapshot Offload or right-click on the snapshot sub-policy and click Add Snapshot Offload. In the Options pane, set the snapshot offload sub-policy options.
    Keep Snapshots
    After a certain number of snapshot instances are created for a resource, older instances are purged from the storage controller. Enter the age of the snapshot instances to purge in the Days field, or the number of instances to keep in the Snapshots field.
    Tip: The IBM Storage Defender Copy Data Management user interface indicates that a Pure Storage FlashArray CloudSnap offload job has been completed even though the transfer is still occurring in the background, which depends on network speed. Consider setting an age as the retention for offload copies when you use the Pure Storage FlashArray CloudSnap functionality to ensure that a sufficient amount of time has passed for data to be transferred to the S3 storage target or NFS share before it must be condensed out from a backup. This is important if several offload jobs are run in quick succession.
    Offload Target
    Select the offload target.
    Note: IBM Storage Defender Copy Data Management does not support the Cloud option as a snapshot offload target.
    Snapshot Prefix Label
    Enter an optional label to identify the snapshot. This label is added as a prefix to the snapshot name created by the job.
    Tip: Snapshot labels must contain only alphanumeric characters and underscores.
    Name
    Enter an optional name to replace the default snapshot sub-policy name displayed in IBM Storage Defender Copy Data Management. The default initial name is Snapshotoffload0.
