The configuration details of managed devices (including Enterprise Manager™ itself) are contained in a compressed user configuration set (UCS) file with the extension of .ucs. This file contains all of the information required to restore a device's configuration, and consists of these elements:
Enterprise Manager saves UCS files to a UCS archive. You can create a task to save UCS archives for devices at regularly scheduled intervals. Archives that are created and saved on a schedule are called, rotating archives. When the system creates rotating archives, it compares the most recently stored UCS archive file to the current configuration on the device at the specified interval. If there are any differences, Enterprise Manager stores a copy of the current configuration in a UCS archive. If there are no differences, Enterprise Manager does not store an additional copy of the current configuration, which leaves you room to store a higher number of unique historical UCS archives. When Enterprise Manager reaches the maximum number of archives specified to store, it deletes the oldest archive in the rotating archive list. By default, Enterprise Manager stores up to 10 rotating archives each, for itself and every managed device.
Another option for archive storage is to create an archive of a specific UCS for a device, referred to as a pinning an archive. Enterprise Manager also creates a pinned archive of a device's current configuration before it installs new software. Pinned archives are stored until you delete them.
In addition to storing UCS archives of the configuration for each managed device and itself, Enterprise Manager™also stores configuration data required specifically for managing devices. This archive is called an advanced UCS archive and includes:
Enterprise Manager™ stores all of the information required to manage devices in your network and you have the option of creating a UCS archive of this information. Creating a UCS archive for this information ensures that you have a complete backup file for the Enterprise Manager in the event that a system restore is required.
By default, Enterprise Manager™ saves 10 rotating archives and 10 pinned archives per device. You have the option to increase or decrease the number of archives stored by default. If you decrease the number saved, you free disk space on the Enterprise Manager device. If you increase the number, you have less disk space for storing other data.
