I just got my home server up and running and was wondering what you guys recommend for backups. I figure it will probably be worth having backups on cloud servers tjay are external, are there any good services yall use for that?

As dumb/simple/boring as this may be...? An external hard drive.

....

....what? It doesn't require you to be online 24/7, works at any(tm) PC, and the speed is really great -- even on a potato.

Unless you work at NASA or at IBM or similars -- then feel free to call me dum.

While I agree with you, hard drives do have a shelf life. How many years seems to be up for debate but it does exist. If you don’t have multiple drives that are of different ages you may be in a world of hurt one day.

Why? If you check the drive once a month, and it fails once per 10 years on average, the time when both the back up drive and the main drive fail simultaneously is on average 2340 years. Of couse they are much more likely to fail if they're old but the odds are very small.

I have a hot storage NAS that backups to a warm storage NAS.

I backup every week and scrub every month.

I have 2 x ZFS1 pools that contains 3 x 20TB disks each.

With ECC ram, scrubbing, and independent pools, it'll take a house fire to kill my local storage.

I also have a constant backing to Backblaze and yearly encrypted backup that I ship to a friend across the world.
