directory). See see Working with Directories on page 122..

4. Enter the tar command.

• To backup to a tape, use the syntax tar cvf /dev/rmt/0

<sourcefiles>.

• To backup to the present working directory, use the syntax

tar cvf <archivefile.tar> <sourcefiles>. Use

cp to place the tar file in an alternate directory or drive.

bines and saves the source file(s) in the archive file

ups can also be made to an alternate directory or internal drive. See the

mands.
