Backing Up the Database
A backup copy of the database is automatically stored on the Inter-Tel memory card. This
backup remains available, even if the system experiences a power failure or if the battery
backup loses power. If the system is powered up and a corrupt database file is detected, the
backup file in the memory card is restored.
This backup database is designed to recover in the event of a total power failure—it is not
designed to replace the static database. Changes made to the static database are not reflected
in the backup database until the database is automatically or manually backed up. For example,
if you default the database, the static database is defaulted, not the backup database.
The backup database allows the system to automatically convert databases when the software
is upgraded. For example, if the system is upgraded from v1.01 to v1.02, the v1.01 static
database is detected and considered corrupt. When this occurs, the system restores the backup
database and converts the information to a v1.02 static database. The backup database
version, however, does not change until a backup is performed (it remains a v1.01 database).
The system repeatedly attempted to restore a backup database but was interrupted by power-
ups. If the static database is corrupted, the system attempts to restore the backup database. If
the system detects problems with the backup database, it may default the static database
instead of restoring the backup database. The database will be defaulted if one of the following
occurs:
•
There is no backup database available.
•
The system was saving the backup database when the power down occurred.
•
The system repeatedly attempted to restore a backup database but was interrupted by
power ups. The system will default the database after it has exceeded the number of
restore attempts, as specified in DB Programming—refer to the
Inter-Tel 5000 Features
and Programming Guide (part no: 580.8006) for details. If this occurs, the backup
database remains in flash memory for troubleshooting purposes.
If desired, you can force DB Programming to save the backup file immediately, as described
below. To set Backup Database Save parameters, refer to the
Inter-Tel 5000 Features and
Programming Guide (part no: 580.8006).
To force a backup database save:
1. From the DB Studio menu bar, select Operations – Database Operations – Backup
Database Save .
2. Click Start to create the backup. The backup file is saved and stamped with the new
date/time.
NOTE The Voice Processor database is not stored in flash memory.
