Maintaining IS-III

Backing Up the System

The information saved during a backup can be used to restore IS-III in the unlikely event of a catastrophic failure. You should back up your files when subscriber information or prompt messages are changed. It is best to perform backups in the evening or when the telephone system is not busy. Backups performed during busy hours may cause reduced system performance warning messages.

IS-III supports the following backup procedures:

■complete system backup to tape, which saves all of the IS-III files. This includes the following items:

—UNIX files

—integrated administration (Extension Directory) files

—administrative files for each application

—all voice system files (if AUDIX Voice Power is installed). These files include all voice mailbox messages, system greetings, and personal greetings.

—all fax messages (if FAX Attendant is installed). These files include Fax Response files.

NOTE:

Prior to performing a complete system backup to tape of IS-III, back up switch programming to the hard disk (via SPM). Backing up the switch programming to hard disk before performing a complete system backup to tape ensures that you have a backup of the switch programming on tape. Your backup tape will contain all the IS-III information and the switch programming. See the AT&T MERLIN LEGEND™ Communications System Release 2.0 System Programming document (Document No. 555-620-111) for SPM backup procedures.

■back up administrative files to diskette, which saves the following items:

—UNIX files

—administrative files for each application

—voice system files (if AUDIX Voice Power is installed). These voice system files do not include voice mailbox messages, system greetings, and personal greetings.

When you back up the administrative files to diskette, fax messages (including Fax Response files) are not saved.

■back up integrated administration files to diskette, which saves the files associated with the Extension Directory.
