Configuring Automatic Snapshot Retention on a Target (CLI)

Use this procedure to set a different number of retained automatic snapshots on the replication target than what was set on the source appliance. Before performing this procedure, you must set a replication action on a project or share, and schedule automatic snapshots.

When performing this task, modify the replication action and the snapshot schedule from the appropriate project or share. If the replication action and snapshot schedule are set at different levels, edit the replication action at the same level where the schedule is configured, as shown in the following table:

See Replication Automatic Snapshot Management for more information.

Before You Begin

Before configuring automatic snapshot retention on a target, you must first do the following:

• Create a replication action on a project or share: Creating a Replication Action (BUI).

• Create an automatic snapshot schedule for the project or share: Scheduling Snapshots (BUI).

1. On the source appliance, go to Shares and select the appropriate project or share with the replication action and snapshot schedule.

   hostname:> shares select MyProject
   hostname:shares MyProject> select MyShare
   hostname:shares MyProject/MyShare>
   

2. Enter replication, then enter show to display existing actions.

   hostname:shares MyProject/MyShare> replication
   hostname:shares MyProject/MyShare replication> show
   Properties:
                        inherited = false
   
   Actions:
   
               TARGET          STATUS     NEXT
   action-000  local           idle       Thu Jan 05 2017 12:04:00 GMT+0000 (UTC)

3. Select the action for which you want to modify retention settings.

   hostname:shares MyProject/MyShare replication> select action-000
   hostname:shares MyProject/MyShare action-000>

4. Enter autosnaps, then enter show to display snapshot schedules.

   hostname:shares MyProject/MyShare action-000> autosnaps
   hostname:shares MyProject/MyShare action-000 autosnaps> show
   Properties:
     autosnaps_retention_policies = independent
   
   Automatics:
   
   NAME           FREQUENCY      DAY             HH:MM KEEP
   automatic-000  hour           -                -:04    3
   
   

5. Select the automatic snapshot schedule that you want to modify. Then use set keep= to set the number of automatic snapshots to be retained on the target.

   hostname:shares MyProject/MyShare action-000 autosnaps> select automatic-000
   hostname:shares MyProject/MyShare action-000 automatic-000> set keep=10
                             keep = 10 (uncommitted)

6. Enter commit to save the changes, and enter show to verify that the keep property has changed.

   hostname:shares MyProject/MyShare action-000 automatic-000> commit
   hostname:shares MyProject/MyShare action-000 automatic-000> show
   Properties:
                        frequency = hour
                              day =
                             hour =
                           minute = 04
                             keep = 10
