If you guys are writing post-mortem blog posts due to running out of disk space, your solution should really be to hire a sysadmin or ops-focused engineer. Disk-related issues are among the easiest to diagnose, so take this experience as a wake-up call that your current team is in over your heads. If you can't afford a sysadmin or don't want to bring that kind of talent in-house, you can try using a hosted solution. But make sure to really test out different hosted services before committing to one, since they can vary tremendously in terms of quality and reliability.
