Snapshots are typically part of the provider's web management interface and are basically the first thing anybody who makes changes to anything should learn how to use. Moreover, if you're having someone else manage your systems and they upgrade them, now what do you do when the new version causes problems? I ran into an issue recently where newer systems default to a newer version of a protocol but the implementation of the newer protocol has a major bug the old one didn't. When that happens on your systems you roll back until you can solve the issue. When it happens on systems managed by someone else, better hope you can identify and solve the issue quickly because in the meantime your system is broken.
