You should automate some basic restore testing of your backups
Everyone says that you don't really have backups until you've tested that you can restore them (and I have some hair-raising stories about that, where I was lucky to avoid a disaster). The corollary to this is that it's a really good idea to automate at least a basic test of reading your backups and perhaps restoring something from them. This doesn't have to be particularly elaborate. For example, you could have a few canary files in various places where you write the current day's date before you start backups, and then afterward you can try to restore a random canary file and see if it has the right date.
