Full Discussion: Backing up an entire HD

Try tar with compression. Since you have a lot of data consider basing your creation of tar files on the existing directory structure, rather than using exact image opies of your disk.

You will need storage somewhere, not on the disk you are backing up, for the files you create.
Example back up of a primary directory.

Code:
cd /path/to/root_of_disk_device  # the mountpoint or the / directory
tar cfz /path/to/backup/device/music.tgz ./music

Why make smaller backups? You want to restore a file. To recover anything that large, decompressing 600 GB and searching for, and restoring filenames is tedious on huge backup files. And requires lots of resources.

Also consider making incremental backups, like once a week. Backup any file that is newer than the time and date of your last backup.

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.
