Configuring Automatic Snapshot Retention on a Target (BUI)

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:

Action

Modify automatic snapshot retention on:
Project level
