A StorSimple Data Protection Policy allows you to define the schedule and parameters for taking Snapshots and Cloud Clones for your selected StorSimple Volume Groups.  The StorSimple Data Protection MMC Snap-in gives you the flexibility of starting interactive backups instantaneously.  It also provides the ability to define long term backup schedules, including start and expiration dates, times, frequencies, and retention policies for your snapshots, Cloud Snaps, and Cloud Clones.

A left click on the ‘Policies’ object in the scope pane enumerates the following in the results pane:

 

  • Name – names of all the existing StorSimple data protection policies
  • Type – column indicating the type of policy, i.e. Snapshot, CloudSnap, or CloudClone
  • Created – column indicating the date and time of creation of each policy
  • Retention Count – displays how many backup copies created as a result of that policy that will be retained

 

The right actions pane presents you with a link to create a policy, which is also available when right-clicking the ‘Policies’ entry in the scope pane.

Once created and enabled, the policy will be applied immediately to the volume group and will be executed as per your specifications.

Create Policy

A right click on the policy node displays an action to create a policy.  This action can also be selected from the right action pane.

Choosing to create a policy will present you with a dialog box that allows you to specify the general parameters and schedule for your new policy.

On the general tab, specify a name for your policy.  This name must be unique across all policies created on this server.  Specify a volume group, which is the series of volumes you wish to perform backup operations against.  Choose the type of operation (Snapshot, Cloud Snap, Cloud Clone) which defines the type of backup operation to perform.  Then, specify the retention requirement for this backup.  The retention settings allow you to either retain all backups created by this policy (by checking the checkbox next to ‘All’) or a specific number of backups. 

 

Note

Choosing to retain all backup copies will cause the policy to become disabled once the maximum number of backup copies has been reached (currently 64 per volume).

 

The schedule tab allows you to specify the frequency of the backup operation and additional scheduling parameters.  Use the radio buttons in the ‘settings’ section to specify a one-time operation, daily operation, or weekly operation.  Use the ‘start’ fields to specify when the policy should start for the first time.  The timestamp in the ‘next run’ field shows when the policy will execute next.

In the ‘Advanced Settings’ section, you can specify the repetition for this policy, its expiration, and whether or not the policy is enabled.  Choosing a ‘repeat’ value will cause the policy to repeat regularly until the specified duration has expired.  For example, a policy configured as ‘one time’ with a repeat value of ‘1 hour’ for a duration of ‘1 day’ will run each hour for one day, and then no longer run. 

 

Setting the expiration will cause the policy to become disabled once the expiration time has been reached.  Unchecking the box next to ‘enabled’ will cause the policy to no longer execute.

 

Note

Only one instance of a given policy can run at any time.  If you schedule the policy to repeat in a period of time that is less than the amount of time needed to complete the previous iteration, the next iteration will not start.  An iteration of a policy will not start if the previous iteration is still running.

 

Once you click the Accept button the new policy will be added to the list of existing policies in the result pane, and if enabled, the policy will be displayed in the scheduled jobs list along with the time and date of its next run.

 

Right-clicking a policy in the tabular list presents you with the option to update an existing policy, which allows you to edit the parameters described above, or the option to delete a policy.

To delete a policy, select the delete action from its context menu or the right action pane.  A delete confirmation box appears, requiring you to confirm that you wish to delete the policy.

Selecting Yes will delete the selected policy whereas selecting No will cancel the action.

Deleting a policy will not affect the associated volume groups, and does not delete the backups that were created by this policy.

 

Note

Deleting a policy does not delete the backups that were created as a result of that policy.  Backups need to be deleted manually.
