Thanks for the information.
Yes I agree no need to tar the mysqldump thanks for pointing this out. Im using gzip because the files are over 3 Gig and saves on cpu and memory...so i have heard.
Could you gzip the mysqldump + files_backup.tgz to make a new gzip file in one command...e.g.
files_backup.tar.gz <--- already exists
db_backup.gz or db_backup.sql
So to go over it again because im confusing myself
files_backup.tgz has already been made before I run mysqldump so dont need to create it.
Then from the mysqldump command gzip the sql file e.g. db_backup.gz or not. Then gzip both files sql & files_backup.tgz...???
