Db backup scripts

various.sh

 for DB in $(mysql -u root -p<password> -h <IP of DB> -e 'show databases' -s --skip-column-names); do
 mysqldump -u root -p<password> -h<IP of DB> $DB > "$DB.sql";
 

A quick script from any networked machine or even the host;

for DB in $(mysql -u root -p<password> -h <IP of DB> -e 'show databases' -s --skip-column-names); do
mysqldump -u root -p<password> -h<IP of DB> $DB > "$DB.sql";
done

Dumps out all the databases in the mysql/mariadb instance to individual .sql files. If you need to restore, just mysql -u root -p -h < file.sql

I have this running in a CRON job every four hours against my MariaDB Galera cluster. I periodically test restores on a test MariaDB or mysql instance by doing a restore and attempting queries.

I like to mysqldump | gzip --rsyncable | restic --stdin

works great, deduplicated snapshot directly into a cloud bucket
