the current step of the backup operation and then cancels the backup
operation.
Depending on the size of your database, some of the steps in the backup
operation can take several minutes to complete. Please allow time for the
system to complete the current step and respond to your cancel
command.
You can restore a database using a backup file that is from the same
version as the running system software. For example, to restore the data
on a system running version R4.3.3, use a backup file from R4.3.3; do not
use a backup file from R4.3.2 or lower. If you restore a database that you
saved on an older release, the operation will succeed. However, if there is
a change in the database schema between the old and new releases, the
restore will fail.
You can convert configuration data stored with an older software version
to a newer software version. You might need to do this if you have
installed a new version of the software but you want to use older
configuration data. During normal operation, you do not need to use this
function.
CAUTION: 3Com does not support the restoration of a database from an
older version of the system software. In addition, you can severely
damage an NBX 100 system if you try to restore a database from a
V5000,V3000, or V3001R system. Do not attempt this operation under
any circumstances.
The backup of your system data includes voice mail messages only if you
specify that you want it included. If voice mail was not included when the
system data was backed up, you cannot specify that you want to restore
voice mail during a restore operation.
Backing up and restoring your licenses are procedures that are separate
from the database backup and restore procedures. Back up your licenses
before and after you add or remove any licenses.
To restore your database from a saved backup file:
1 Log on to the NBX NetSet utility using the administrator login ID and
password.
2 Click System Maintenance > System Restore.
