MySQL backup script

Feature rich MySQL / MariaDB backup script.

Installation

git clone https://github.com/1sept/mysql_backup.git
set database user and password in .my.cnf located in user homedir.

Example

Usage: mysql_backup.sh -d /backup/dir/ -n daily [-c 10 -s -z -e test@domain.org]

Options

-d , --dir
backup directory
-n, --name
backup name
-c, --copies
number of copies to store (default 10)
-e, --email
email to send notifications
-l, --lock-all-tables
lock all tables across all databases. This is achieved by acquiring a global read lock for the duration of the whole dump. This option automatically turns off --single-transaction and --lock-tables. WARNING!!! This will block all applications. -s, --single-transaction
this option sets the transaction isolation mode to REPEATABLE READ and sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time when START TRANSACTION was issued without blocking any applications.
-z, --compress
compress dump using gzip
-q, --quiet
-h, --help

Setup script in crontab

20 01 * * * root /bin/sh /path/to/mysql_backup.sh -d /backup/dir/ -n daily -c 10 -e admin@email.com -z -q
