What is Rsnapshot?

From the official website: “rsnapshot is a filesystem snapshot utility based on rsync. rsnapshot makes it easy to make periodic snapshots of local machines, and remote machines over ssh. The code makes extensive use of hard links whenever possible, to greatly reduce the disk space required”.

Setup mysql client

Install mysql-client if not installed, this will provide the mysqldump utility

apt-get install mysql-client

cp /usr/share/doc/rsnapshot/examples/utils/backup_mysql.sh /usr/local/bin/

Make sure your backup scripts are owned by root, and not writable by anyone else.

chown root.root /usr/local/bin/backup_mysql.sh
chmod o-w /usr/local/bin/backup_mysql.sh

This scripts is designed only to back up all databases to a single file.

Edit script

nano /usr/local/bin/backup_mysql.sh

replace

/usr/bin/mysqldump --all-databases > mysqldump_all_databases.sql

with

/usr/bin/mysqldump --defaults-file=/etc/mysql/debian.cnf --all-databases > mysqldump_all_databases.sql

If you need to dump a single database use line below

/usr/bin/mysqldump --defaults-file=/etc/mysql/debian.cnf DATABASE > DATABASE.SQL
