Concept
Automatic Purge of Backup Sets
An Enterprise Server stores multiple local and remote backup sets. As a result, these sets can consume much needed space on the Enterprise Server. To resolve this problem, you can configure the Enterprise Server to remove outdated backup sets.
You configure purge settings on an Enterprise Server, rather than SmartStruxure server devices. For more information, see Backup and Restore Manager on the Enterprise Server .
You can set the maximum number of local and remote backups that you want to store at a given time on the Enterprise Server. The system compares two values: the maximum number that you configured for the Enterprise Server and the date stamp on each stored backup. Whenever a new backup is created, the most recent backup set replaces the most outdated backup set. In other words, the system adds a file and then deletes the oldest file to maintain the maximum number that you configured for the Enterprise server.
You can manage automatic purging on an Enterprise Server by configuring a maximum number of files to store. There are two purge settings:
Local setting for the Enterprise Server: The local setting, Number of local backup sets to store , manages the backups stored on an Enterprise Server.
Global setting for SmartStruxure server devices: The global setting, Number of AS backup sets to store , manages all the backups stored on the SmartStruxure server devices. You cannot configure each SmartStruxure server device separately because the global setting affects all the SmartStruxure server devices created under the Enterprise Server.
You can vary the number of local and remote backup sets that you store. For example, you can configure the system to store a maximum of five local backup sets for the Enterprise Server and two remote backup sets for each SmartStruxure server device.
By default, Building Operation enables automatic purging for both local (Enterprise Server) and remote (SmartStruxure server devices) backup sets. However, you can disable this feature to ensure that all manual and scheduled backup sets are automatically stored on the Enterprise Server.
