Setup is made populating the BACKUP_DATABASES environment variable with a list of backup configuration. Each backup setup must be in a single line and have two items: a database URL and a cron-like string indicating the periodicity of the backup.

Examples

All examples listed refer to the (hipotetical) mysql server mydatabase.com.br logged with the username db_user:

schema: mysql (at this moment is the only database supported)
username: db_user
host: mydatabase.com.br

mysql://db_user:123456@mydatabase.com.br:3306/database-to-backup @hourly

password: 123456 (login will be attempted with this password)
port: 3306 (as it is the default port for mysql it could be ommited)
database: database-to-backup (only this database are going to be backuped and ommiting this value will vary depending on the database, generaly meaning backuping all accessible databases)
schedule: @hourly (each 60 minutes, with the first occurence 60 minutes after starting the system) mysql://db_user:123456@mydatabase.com.br 0 0 1 * * *
password: 123456 (login will be attempted with this password)
schedule: 0 0 1 * * * (in (GO implementation cron format)[https://godoc.org/github.com/robfig/cron])meaning on this case every night at 01h00) mysql://db_user@mydatabase.com.br/* @daily
schedule: @daily (onde a day starting 24h from starting)
