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 .
