Then there is the data corruption , perhaps viruses and other things which may Cause problems or ruin your data. Your data may be ruined , then copied to backup which is there but no use. Imagine i have txt doc and something happens to it and may overwrite a known good file
Businesses use RAIDS to deal with HDD failures, they do full back ups or incremental back ups (ideally on different physical location) and tape back ups.
Some software requires specific back up methods and data wont work without it been Done correctly.
You may want to speak some IT guy but if you dont understand how it works youre pretty much alone When something goes wrong.
I dont know how important the data is but you could do something simple as copy new files to one or two external hdd as u have new files .also burn 1 or 2 copies on dvd and keep them (or 1hdd and 1/2Dvd or Any similar media) on different location.
You still need to verify once in a while that your back up files are working. Cloud is one option as well.
It all depends how important the data is. Company can go out of business due to a data loss, For others just major inconvenience.
I wouldn't use raid 5 and it's important not to conflate raid with backup just to be clear. For the small or home office truenas/freenas at freenas.org can connect you with professionals that can deploy a rock solid storage built with zfs, truenas being the turnkey enterprise product and freenas being the diy if you are tech savvy. It supports jails for code42 or owncloud/nextcloud or offsite backup through rsync and full support for snapshots and other common enterprise needs.
Very easily scalable, can add hard drives modularly to the pool if your needs grow and connects over local network to all your devices through all the major connection types available today.
Still, it's far cheaper and more effective if your usage is at the level OP described to do onedrive, and that would allow him to send email links to collaborate instead of trying to learn how to send large files too big for email through alternate means
