Ahahaha nice comment. I never said I didn’t have backups, the thing is that once you get your data across multiple machines with something like Synching your life becomes way better and things are easier to deal with. Even if my “server” dies I still have three more real time copies of the data (or at least one actually real time and two others a bit behind because those machines aren’t always turned on) and the “server” backups to another local drive a long term offsite backup that gets updated from time to time.
I’m not sure what your comment has to do with partitioning, though.
People usually go about and suggest partitioning their disks because they might require to reinstall the system and that way your home directory “will be safe” from whatever mess forced them into a reinstall. In reality this will just introduce unnecessary complexity and it is as likely to fail as single partition system. To be fair I would rather consider a BRTFS sub-volume for home with regular snapshots is way more interesting and manageable than just dumb partitions.
