Just a reminder. Consider and test your restore process as well. Backups without restore testing are kind of questionable. Also think how the restore will go. Do you want to do a bare metal restore, or will you just reinstall, and restore certain things for example. Lot of these backup methods will not get a true bare metal restore set, nor can file system backups be "perfect" if they are done on a running system. Databases and things like cryptfs mounts for example can be problematic for example. Nor do all tools necessarily backup the full structure of the file system.

Not saying these are always issues, just be aware of them.
