Table 10-2 Commonly used flags for the savevg command

Flag Description

-e    Excludes files specified in the /etc/exclude.vgname file from being backed up by this command.

-f     Device Specifies the device or file name on which the image is to be stored. The default is the /dev/rmt0 device.

-i     Creates the data file by calling the mkvgdata command.

-m   Creates the data file with map files.

-p    Disables software packing of the files as they are backed up.

-X   Specifies to automatically expand the /tmp file system if necessary.

 

The savevg command uses a data file created by the mkvgdata command. The

data file created is as follows:

/tmp/vgdata/vgname/vgname.data

The vgname.data file contains information about a user volume group. The

savevg command uses this file to create a backup image that can be used by the

restvg command to re-create the user volume group.
