usage:

backup.sh local

Dependencies:

rsync - for backing up files mysql - if you want to backup mysql db's bc - calculations

NOTE:

Backing up over SSH assumes you have a profile for the target setup in your ~/.ssh/config file.

Options:
  --target=<name>      Specify the backup target.
  --local              Run the script in local mode.
  --mysqluser=<user>   Override the default MySQL username.
  --mysqlpass=<pass>   Specify the MySQL password.
  --help               Display this help message.

Examples:
  $0 --target=production
  $0 --local
  $0 --mysqluser=admin
  $0 --mysqluser=admin --mysqlpass=supersecure
  $0 --target=staging --local --mysqluser=admin --mysqlpass=topsecret

TODO

• source ~/.backup.conf for settings
• REALLY test and fix deleting old backups
• add -l switch for local
• remove the whole "bastion" thing. We should use ssh ProxyJump instead
• remove bc as a dependency
