8.1 BACKUP OVERVIEW
The DVR unit can easily backup important video to an internal or external media location. The most commonly
used are CD-RW drives and Hard Drives. Since the DVR unit comes standard equipped with a CD-RW drive, this
section covers backing up using the CD-RW drive as well as by using a Hard Drive.
The DVR unit backs up using a proprietary compression format that can only be read by the DVR Backup
program. This ensures the integrity of the data. In addition the CD-RW also uses a proprietary format in which it
stores the information. This format, called UDF, can only be read by a Computer which has the UDF reader
software installed. A copy of Roxio® UDF Reader is on the Software Installation CD shipped with the DVR unit.
A copy is also available for download from Roxio® direct (
http://www.roxio.com).
During the backup process the DVR unit will never stop recording. The DVR unit is a multiplexing unit that can
perform virtually all functions without having to stop the recording process.
In addition, you can now backup to multiple CDs when the file sizes exceed the size of one CD. Also, you can
specify multiple locations to save to. For example you can save 1/3 the data to a CD, 1/3 the data to the local
Drive and 1/3 the data to a network drive.
