Delete Node Data from a Data Store

As a storage administrator, you may want to delete backed-up node data from a data store to free up space and effectively manage your storage space. Arcserve UDP lets you select the node data in a data store and delete. You can select multiple nodes in a data store. You can delete any type of node data including the encrypted and deduplicated data. The data store should be in the running state when you start this job, called as Purge job.

Note: You can delete only when the node is not running any job (For example, Backup / Restore / Merge job).

Follow these steps:

1. From the Console, click the resources tab.
2. Click the data store that contains the node data that you want to delete.
3. The Recovery Points Summary page appears.
4. Select the node that you want to delete.

   Warning! Only select, do not click the node name. Clicking the node name leads to another page from where you cannot perform the delete action.

5. Click Actions, Delete.

   Note: If you are using deduplication data store, after deleting the recovery points of a node, the disk space may not be released immediately. The delay happens because for deduplication data store:

   • The backend purge and reclamation process is scheduled at the idle time of data store.
   • Part of the data blocks of the deleted recovery points of that node may still be used by recovery points of other nodes.

     The volume of reclaiming the disk space depends on the deduplication ratio of the node that you want to delete.

6. Confirm that you want to delete the node data.

The purge job is initiated and the node data is deleted from the data source. You can see the status of purge job from Recent Events and logs.
