Operating Systems AIX AIX backup and restore Post 49761 by Optimus_P on Friday 9th of April 2004 03:46:11 PM

if your looking just for a copy of all the files then just tar it all up and put it on another vg.

but if you render the rootvg inoperable in your testing your going to want a mksysb tape to boot from and restore to the contents on tape.

you could always use the backup command and direct the contents to the remote drive. but again have a mksysb avaliable incase you destroy the rootvg.

Code:
man backup

-f Device Specifies the output device. To send output to a named device, specify
the Device variable as a path name (such as /dev/rmt0). To send output to the
standard output device, specify a - (minus sign). The - (minus) feature enables
you to pipe the output of the backup command to the dd command.

You can also specify a range of archive devices. The range specification must be
in the following format:
/dev/deviceXXX-YYY

where XXX and YYY are whole numbers, and XXX must always be less than YYY; for
example, /dev/rfd0-3.

All devices in the specified range must be of the same type. For example, you
can use a set of 8mm, 2.3GB tapes or a set of 1.44MB diskettes. All tape devices
must be set to the same physical tape block size.

If the Device variable specifies a range, the backup command automatically goes
from one device in the range to the next. After exhausting all of the specified
devices, the backup command halts and requests that new volumes be mounted on
the range of devices.

/usr/sbin/backup -f <DEVICE> -0 -u <FS>
