ARCHIVE FEATURE Description

The goal of database archive i s to allow a system that has suffered
catastrophic data loss or other failure to restore itself to working condition.
EliteMail VMS/EliteMail Limited retains a default system database and the two
most recent databases.
EliteMail checks daily to determin e if the database should be archived. If
necessary, the system builds a compressed file containing the system
database and all user greetings. The compre ssed file is then moved to the
ARCHIVE directory on the EliteMail hard drive.
During bootup, EliteMail d etermines if an archived database shou ld be
restored. If necessary, the system purges unusable data from the working
directories and restores a database f rom the ARCHIVE directory.
