Cisco Unified MeetingPlace Express uses a combination of L0, L1, and L2 backups and uses an Informix command called ontape for the backup mechanism.
The database backup file is physically located on the system disk, which is the same physical device on which the rest of the Cisco Unified MeetingPlace Express system exists. The system disk can contain up to three automatically-created L0 backups: the current L0, plus the previous one or two L0 backups. The L1 and L2 backups are also kept there. All of the older backups are removed from the system disk during the cleanup process.
For more information on the backup and restore of MeetingPlace Express data, see the Configuration and Maintenance Guide for Cisco Unified MeetingPlace Express Release 2.0, "Maintaining the Cisco Unified MeetingPlace Express System"
