# You may need to use a different tool if start-stop-daemon is not available for your Linux distribution.

# Example crontab entry:

# Every two hours, this will backup, delete backups older than 30 days, and garbage collect

# Uses start-stop-daemon because, for a given replica ID, only one write-capable operation should run at once.
