Backing Up User Files
To determine the size of the HOME fileset, for example:
1. Determine the subvolume name of the fileset by obtaining its DEVICELABEL value
from the fileset definition. The last five digits in the Guardian subvolume name
(which begins with ZYQ) correspond to the DEVICELABEL value.
For the HOME fileset in this example, the DEVICELABEL is 000001, so this
fileset’s subvolume name is ZYQ00001.
2. Use the following form of the TACL DSAP command to determine the size of the
fileset:
DSAP oss_volume_name, BYSUBVOL
You need to do this for all volumes that contain files with the subvolume name for
the fileset. To determine the list of volumes with subvolumes, you can use the
command:
FUP SUBVOLS $*.ZYQnnnnn
For the HOME fileset example, the commands would be:
FUP SUBVOLS $*.ZYQ00001
If the output of this SUBVOLS command was:
$OSS2
ZYQ00001
$OSS1
ZYQ00001
$OSS
ZYQ00001
then the corresponding DSAP commands would be:
DSAP $OSS2, BYSUBVOL
DSAP $OSS1, BYSUBVOL
DSAP $OSS, BYSUBVOL
Figure 6-4
on page 6-21 shows the output of one such DSAP command. The total
number of pages in a fileset on one disk is shown in the Total Pages column for its
subvolume. To determine the total number of bytes, multiply the total pages by
2048 (the number of bytes/page).
