Configuring Snapshot Schedule Policies
You can configure snapshot schedule policies that create snapshots on a scheduled basis when applied to a configured LUN.
All the snapshot schedules are added in the Snapshots page on the Core, from where they then get pushed to the Edge. The Core has a default snapshot policy called default_policy that is triggered every four hours starting at midnight.
To apply a policy to a LUN configuration, see
Applying a Snapshot Schedule Policy to a LUN.
To configure policies for a snapshot schedule
1. Choose Configure > Backups: Snapshots to display the Snapshots page and select the Snapshot Schedule Policies tab.
2. Add new snapshot schedule policies using the controls described in this table.
Control | Description |
Add a Snapshot Policy | Displays controls for adding a snapshot schedule policy to the running configuration. A maximum of five snapshots are held by default. |
Snapshot Policy Name | Type a descriptive name for the policy: for example, snap_policy_early. |
Automatically take snapshots | Specify the interval for the snapshot policy: • Every week... - Select this option to specify a day and time for the snapshot. • Every [specific weekday]... - Select this option to specify one or more week days and time for the snapshot. • Every day... - Select this option to specify one or more specific times for a daily snapshot.

For example, you can have hourly, daily and weekly schedules, all as part of the same policy. |
