Using Run Options in a Backup Command
Specifying Backup Recording Density
If you are using a tape drive that supports the density selection, you can specify one of
three recording densities (in bits per inch):
•
6250 bpi
•
1600 bpi
•
800 bpi (G-series only)
To specify a recording density, include the DENSITY option and a density setting in
your Backup command. For example:
The tape drive then generates a tape with the recording density you specified. If you do
not specify a density, the tape receives the current density setting of the tape drive.
Listing All Files During Backup
Backup lists or displays the names of the files that are backed up. By default, the
Backup listing includes only files that generate error or warning messages. Backup,
however, can list all files that are backed up, in addition to any error messages, if you
use the LISTALL option.
The Backup listing is displayed at the OUT file you name in your Backup command; if
you omit the OUT option, Backup uses your terminal. Regardless of the listing device
you specify, messages (including errors and instructions) are also sent to the terminal
where you entered the Backup command.
This example shows a listing generated by Backup without the LISTALL option:
Backup displays:
In the above example, two attempts to copy files resulted in errors. The error number in
parentheses identifies a file-system error. For example, error 48 is a security violation;
the user did not have read access to that file.
