+## SQLDump
+## Author: Ze'ev Schurmann
+## Reddit: u/thisiszeev
+
+## This script creates a list of all databases in MySQL or MariaDB and then adds to then
+## list all the unwanted databases. It then creates a list of unique names which are the
+## databases to be backed up. (If you have a root password for MySQL or MariaDB then you
+## may need too include it in the code.)
+
+## Place this script in the folder /var/sqldumps
+
+## It's a good idea to run this in as a cron tab. Then you can time a remote backup from
+## another server/machine.
+
+## Crontab example: (excluding the ##)
+
+## 0 22    * * *   root    cd /var/sqldumps && bash sqldumps.sh
+
+
+
+
+## Put the names of the databases you do not want to backup in the following array.
+
+ignorelist=("mysql" "performance_schema" "dbispconfig" "phpmyadmin" "roundcube")
+
+
+## Put the location for the SQL Dumps
+
+dumppath="/var/sqldumps"
+
+
+## Removes previous SQL dumps and list files.
+
+rm -f *.sql
+rm -f *.list
+
+
+## Creates a list file of all the databases.
+
+mysql -e "show databases" | grep -Ev 'Database|information_schema' > db.list
+
+
+## Add a list of the unwanted databases to the list file.
+
+for ((n=0; n<${#ignorelist[@]}; n++))
+do
+  echo ${ignorelist[$n]} >> db.list
+done
+
+
+## Generate a list of the databases to be backed up and pass it line by line
+## into a while loop, exporting each database to dbname.sql
+
+sort db.list | uniq -u | while read -r dbname; do
+  echo "Dumping $dbname to $dumppath/$dbname.sql"
+  mysqldump $dbname > "$dumppath/$dbname.sql"
