Concept
Automatic Purge of Backup Sets
An Enterprise Server or Enterprise Central stores multiple local and remote backup sets. These sets can consume much needed space on the computer running the Enterprise Server or Enterprise Central. To resolve this problem, you can configure the Enterprise Server or Enterprise Central to remove outdated backup sets.
You configure purge settings on an Enterprise Server, rather than SmartX servers. For more information, see Backup and Restore Manager on the Enterprise Server .
In a multi-server system with an Enterprise Central, you configure the purge settings on both the Enterprise Central and the Enterprise Servers.
You can set the maximum number of local and remote backups that you want to store at a given time on the Enterprise Server or the Enterprise Central. The system compares two values:
the maximum number that you configured for the Enterprise Server or the Enterprise Central
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Whenever a new backup is created, the most recent backup set replaces the most outdated backup set.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 or the Enterprise Central.
You can manage automatic purging on an Enterprise Server or an Enterprise Central by configuring a maximum number of files to store. There are two purge settings:
Local setting for the Enterprise Central or Enterprise Server: The local setting, Number of local backup sets to store , manages the backups stored on an Enterprise Central or Enterprise Server.
Global setting for SmartX servers: The global setting, Number of AS backup sets to store , manages all the backups stored on the SmartX servers. You cannot configure each SmartX server separately because the global setting affects all the SmartX servers 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 SmartX server.
By default, the EcoStruxure Building Operation software enables automatic purging for both local (Enterprise Server and Enterprise Central) and remote (SmartX servers) backup sets. However, you can disable this feature to ensure that all manual and scheduled backup sets are automatically stored on the Enterprise Server or Enterprise Central. For more information, see Backup and Restore Manager on the Enterprise Server .
