About the backup media
The Message Networking system uses rewritable compact disc (CD-RW) media to
back up data. In the event of a system failure, the data stored
on the media is used to restore the Message Networking system to an operational
state.
The CD-RW media used to back up data holds approximately 650MB
of data. You must use CD-RW media that can support a 10x backup.
An average of 10,000 subscribers with voiced names can be stored
per CD during an attended backup. Three CDs are provided with each
Message Networking system. You might need to provide additional CDs for backup
purposes depending on the number of subscribers on your system.
Alternating the backup media
To ensure that acceptable backup data is available when needed,
do not use only one backup CD-RW medium. It is recommended that
you alternate between at least two CD-RW media for unattended backups.
Additional media can be used to implement a longer cycle. For example,
you could alternate backups among seven backup media, each one labeled
with one day of the week.
After an unattended backup is complete or an attended backup medium
is full, label the backup media with the current date or day of
the week, depending on your backup cycle, along with the backup
data type. Then store the backup medium in a secure location. A
second backup medium must then be inserted into the drive in anticipation
for the next unattended backup or to complete an attended backup
if the attended backup requires more than one backup medium.
Replacing the backup media
It is recommended that you replace the backup media every 12 months.
When labeling a backup CD-RW medium for the first time, write the
replacement date on the backup medium to help identify when it needs
to be replaced.
Viewing the contents of the backup
media
The following procedure explains how to view the contents of the
backup media.
To view the contents of the backup media:
- Start at the Administration menu,
and select Utilities > Backup and Restore >
View Attributes of Backup Media.
The system displays the View Attributes of Backup Media page,
which contains the following information:
- The CD-RW medium number, and the name of the machine
- The date and time of the backup
- A list of the data types that were backed up
- A list of the packages installed on the system at the time
of backup
-
Click Return to Main to return to the Administration menu.
Ejecting the backup media
The backup media can be ejected from the drive in two different
ways, either by manually pushing the round eject button on the front
of the drive or by using the Web-based administration pages.
Ejecting the backup media by pushing the button
on the front of the CD-RW drive
To eject the backup media from the drive:
- Press the round button on the lower-right side of the CD-RW
drive.
Ejecting the backup media by using the Web-based
administration pages
Occasionally, you cannot eject the backup media manually, possibly
for one of the following reasons:
- You are at a remote location.
- The system is using the backup medium.
- The backup medium is stuck in the drive for some other reason.
Caution! If you are working from a remote location, do
not unnecessarily eject the backup media.
To eject the backup medium by using the Web-based administration
pages:
- Start at the Administration menu,
and select Utilities > Eject CD.
The system ejects the backup medium and displays the Eject Media
page.
-
Click Return to Main to return to the Administration menu.
