Mirroring keeps your server alive when a disk fails.
Backups keep your company alive in case of a disaster.
With backups you can recover from logical errors, maybe a user deleting a business critical file - mirroring cant help you here.
Business critical servers need both: service continuity (mirroring) in case of a disk failure and business continuity (backup) in case you lose the entire server.

vxconfigbackupd
vxconfigbackupd(1M) vxconfigbackupd(1M)
NAME
vxconfigbackupd - disk group configuration backup daemon
SYNOPSIS
vxconfigbackupd [-l]
DESCRIPTION
The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed.
OPTIONS
-l Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog.
FILES
/sbin/init.d/vxvm-recover
Startup file for vxconfigbackupd.
/etc/vx/cbr/bk/dgname.dgid/dgid.dginfo
Location of backup file for disk group information.
/etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo
Location of backup file for disk attributes.
/etc/vx/cbr/bk/dgname.dgid/dgid.binconfig
Location of backup file for binary configuration copy.
/etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec
Location of backup file for configuration records in vxprint -m format.
NOTES
The vxconfigbackup command can be used to back up a disk group's configuration manually at any 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.
When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed. The only exception
to this behavior is when the disk group is in the precommit state of restoration.
The backup directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size
of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N is the number of
disk groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported
or a configuration change is made.
The default backup directory is /etc/vx/cbr/bk. The location of the backup directory can be configured by using the vxconfigbackup -l
backup_directory_path command.
