MySQL, MySQL Server, Database backups using mysqlhotcopy
Hello,

Currently I have this shell script to backup my databases using mysqlhotcopy and saving 4 previous copies of the backup. The script is working fine and it does the work well. The Only thing I need to add is that instead of creating just the folder of the backup db, it also compress those created folders in a separate gzip files, so that way I can send it via FTP to another serve more easily than transferring all the db file contents.

So basically is change this script to instead of creating the folders like this:
testdb.1
testdb.2
testdb.3
testdb.4

it creates something like
testdb.1.tar.gz
testdb.2.tar.gz
testdb.3.tar.gz
testdb.4.tar.gz

and so on....

That's basically it...

Attached is the code...

Thanks
