To piggyback on Chris' comments, there's a relatively new remote
personal cloud storage option known as the AmberPRO -
https://shop.myamberlife.com/collections/all/products/amber?variant=22314078404666.
Put one of these at a friend's home in another part of the region. Set
it up on its own UPS, with Ethernet surge protection such as this -

to guard against lightning surges. You can even plug in an external
hard drive (or SSD) for additional storage. Hard to beat this option.

The above is true for all manner of "X", that is why you have these
basic rules for backup
1) the data shall always exist on three different physical file systems
2) The data shall always exist at two different geographical locations
3) new data shall never overwrite old data, subject to some reasonable
retention period. This rule is critical. A common problem is file
corruption. You never want the problem where a corrupted version of
a file overwrite the backed up uncorrupted version. You have to keep
the old copies of the files. So re-used backup media is a bad ide.
Batter to just write the changes to the media until the media is full.
Keepingn to overwriting the old data.
You can do this in lots of ways, the common "build vs buy vs rent"
analysis can be applied.
The most common cause for data lost is no longer a failed disk. The
most common is:
#1 Operator error, you delete a file and you don't notice this until
much later.
#2 loss of equipment, misplaced notebook, theft or fire, electric
surge,...
A really good offsite system s to setup a second NAS across town and
let then keep sysnc'd over the INternet. Now you have
second-by-second backup. Is the NAS uses a versioned filesystem then
you have point in time recovery. You can buy the NAS, built is
to rent space on some company's NAS.
A lot depends on if the data is business critical or not. Where I
used to work there where three offsite company own NAS systems.
Triple redundant offsite is kind of nuts for most people but the data
was historic data from past space missions.

of the first 2 but the 3rd has happened.
My 'solution'. Just buy 2 cheap external discs. Backup to both
disks and bring one to a friend/relative (not your neighbour
because if your place burns, the neighbours place will likely
burn too). Next backups backup to the disc at your place and
exchange it with the other one and backup again on this disc.
Some work with minimal cost. So you have 3 different media and 2
different geographical locations.

OK, you don't want to pay to use other peole's storage. Then
buy a second NAS and place it in some other building and use
that. You can work out if it is cheaper to rent or buy
storage. Likely it does cost less in the long run to buy your
own off-site storage but it will require some time for you to
devote to keeping it running. What is your time worth? We
assume this is a business and not a hobby.
The company I used to work for used three large storage systems
each one in a different city and they kept them all in sync.
But they already had IT staff and the server rooms in place.
Synology does make backing up to a remote NAS really easy to
setup. The only problem is the up-front cost is at least
doubled because you need a second NAS box. So you have to
decide if you would rather pay $1,200 for the hardware of $30
per month for a service.
The usual rule of thumb about backing up business critical data
is that is all cases
1) the data is one three different media and
2) the data is at two different geographical locations.
Usually this means the Data is on your computer, your backup
disk or NAS, and in a cloud server. That is three different media.
and your office and the cloud provide two different geographic
locations.
The above is the minimum. Your share holders would consider
you incompetent and sue you if you did less, you can always do more.
