Don't forget to backup your Content Library in some fashion or another. If you want a cheap set and forget type of backup, then I'd recommend Backblaze. If you use the link below, we'll both get a free month. I'm currently backing up with both Backblaze and iDrive. Backblaze will backup every file you have with unlimited space.
Good words and thanks for the heads up. I am in the process of backing up over 60gigs of downloads. I don't worry too much about DS crashing or becoming unstable though 🙂
