-v Specifies that file names should be listed on the screen as the files are being
backed up. This flag cannot be used with the -x flag.

Examples
1. To perform a backup of the /home/tony directory to the backup directory
/usr/lpp/sysback/bf/root, allowing only this user and host to read the file, and
to display a progress indicator, type:
mkdirback -f /usr/lpp/sysback/bf/root -x -r host=h -r user=u -I
tony_tuesday /home/tony
The above will create a file called
/usr/lpp/sysback/bf/root/FD.hostname.tony_tuesday.
2. To perform a remote push backup to virtual device vdev2 on host jupiter and to
make this a compressed backup of the /data/file1 and /data/file2 files, type:
mkdirback -Dph jupiter -f vdev2 /data/file1 /data/file2
3. To perform a backup to rmt1 on the local system of only the files in the /usr
and /var directories that have changed within the last seven days, type:
mkdirback -nm7 -f /dev/rmt1 /usr /var
4. To initiate a pull backup of /home on host lasher, from host sysback1, and send
the data to rmt1 of the host sysback1, type the following from sysback1:
mkdirback -U lasher -f /dev/rmt1 /home
5. To initiate a pull backup of /home on host lasher, from host sysback1, and send
the data to rmt1 of the host shappy, type the following from sysback1:
