There seems to be a misunderstanding. A backup means an exact copy, not a parallel copy. Plus if the data is important, consider getting the backup onto separate media as well.

Why: 'restore a backup' means extracting the backup file into many correctly named files. Correctly named includes the path name. Your backups all have files with the wrong name, unless - to restore - you want to unpack the tarball, then manually copy each file back where it came from.

Not that this will not work. It is duplicated effort and wastes disk space - you actually have 3 copies of each file.

Code:
tar cvfz /path/to/backup/backup_`date +%Y%m%d`.tar.gz /u01/db/mysql

This creates a backup file with the backup date as part of the name, already compressed, on whatever device you choose to place it. Suppose someone then accidentally trashes a file, /u01/db/mysql/scripts/foo.ksh. So. You want to restore it to the way it was before it got munged:
choose the date you want to restore back to, say 20161201. - Dec 1, 2106
Code:
cd /u01/db/mysql/scripts
tar xvfz /path/to/backup/backup_20161201.tar.gz /u01/db/mysql/scripts/foo.shl .

vxconfigbackup

vxconfigbackup(1M)														vxconfigbackup(1M)

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.
