Not for a reliable solution. For example, assume you have a master and a replica database for reliability, what happens if the master, where the cron runs, fails? Do you remember to set up the cron up on the replica? From my experience, having worked on backup software, over 10% of servers that need to be backed up are not. System reliability is hard, and the cloud makes that easier.
