NAME
vxconfigbackup - back up disk group configuration
SYNOPSIS
/etc/vx/bin/vxconfigbackup [-l directory] [[dgname ...] | [dgid ...]]
DESCRIPTION
The vxconfigbackup utility can be used to backup up the configuration information for one or more disk groups. The disk groups may be
specified either by name or by ID. If no disk groups are specified, all disk group configurations are backed up.
OPTIONS
-l directory
Specifies a directory other than the default where the backup configuration files are to be written.
Note: The default backup directory is /etc/vx/cbr/bk.
EXAMPLES
Back up the configuration of the mydg disk group to the directory /dgbackup/mydg:
vxconfigbackup -l /dgbackup/mydg mydg
FILES
/etc/vx/cbr/bk/dgname.dgid/dgid.dginfo
Default location of backup file for disk group information.
/etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo
Default location of backup file for disk attributes.
/etc/vx/cbr/bk/dgname.dgid/dgid.binconfig
Default location of backup file for binary configuration copy.
/etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec
Default location of backup file for configuration records in vxprint -m format.
NOTES
The vxconfigbackupd daemon automatically backs up a disk group's new configuration to the default backup directory whenever the configura-
tion is changed. The vxconfigbackup command is provided to back up the configuration manually at any other desired time.
The disk group configuration backup and restore utilities do not save any data in the public region. This includes file system or other
application data that is configured within VxVM objects.
