PERFORMING THE BACKUP

Regardless of the backup type you have selected, to actually perform the backup, simply
press the flashing EXECUTE key. You will see this screen:
Here, the DD1500 is getting the tape ready for the backup. First of all, it will look at the
tape's directory to make sure that there is no backup of the same name. If a backup of
the same name exists on the tape, you will receive this message:
In this case, press ABORT and give the backup a new name and try again (i.e. press
EXECUTE) or insert a new tape and press CONTINUE.
NOTE: You will need to specifically go to your tape drive use the front panel EJECT key to
eject the current tape and insert a new one.
Assuming everything is ok, the DD1500 will then wind the tape to the first available space
where it can write data. If the tape is a new, freshly formatted tape, this will be quite quick
but if the tape contains several backups already and these contain a lot of data, it may
take a while to wind to the first available area of the tape suitable for backing up to.
NOTE: You may see other messages pop up. These will be momentary - don't worry
about these.
Once a suitable position on the tape has been located, the backup will begin and you will
see this something like this screen as the backup takes place:
The screen shows the progress of the backup as it takes place and this is expressed as a
percentage and as a highlighting bar. The percentage in the top line shows how much of
the individual file has been backed up whilst the percentage in the bottom line shows how
much of the entire backup has been done.
If any of the selected files use audio from any other connected disks, these too will be
backed up to the destination SCSI tape (except in the case where ENTIRE DISK is
selected). During the process, you may abort the backup by pressing the EXIT key at any
time.
The exact amount of time the backup will take depends on the amount of material being
backed up. Backup speed is approximately five times real-time (i.e. ten minutes of audio
will take approximately 2 minutes to backup).
