I’m not considering any plans for Teams as they require a minimum of 3 people.
At the moment, what I store in iCloud is roughly 40GB of data. But, I worry about eventually reaching the maximum capacity of storage. (Dunno if it’s a rational worry, but it’s there). In part, the reason I store little data in iCloud because of this worry. I’d consider putting a lot of the data I backup on Backblaze in to a cloud as well.
You could theoretically do it. I think you’re in for a world of hurt, though.
First off, without going deep into specifics, some cloud systems are designed for fast access, writing and retrieval (the backend of Dropbox, iCloud and such), others are designed for easy storage and slow retrieval, others are designed for long-term cold storage. (B2 tends to be more of the latter.) You don’t need the same access priority or performance if you solely intend to store things for a backup you might need one day (where you do intermittent restores) than continuous access such as live files. It does not cost the same, either, because the data accesses are prioritised differently. (The aforementioned chart is a little dishonest, since S3 and B2 do not really operate on the same level – B2 is for storage, S3, Azure and others are more “live”).
Also, good luck configuring any of those systems for cloud storage daily use if you’re not already very familiar with how they work. I considered using B2 and/or Amazon Glacier for backing up my Synology. The answer? I’m gonna buy a Mac mini to use as a server and slap the consumer Backblaze on it. It’s going to be way, way simpler.
So, daily use for a cloud storage? Well… good luck with that.
iCloud had a 2 Tb plan. Your live files, the ones you need for daily tasks, will never reach that ceiling if you currently have 40 Gb only – or at least, the plans will keep scaling way faster than your needs. (Because they keep scaling every few years, where you get more space at the same price.)
For typical backup storage Degoo has good 10Tb lifetime offers. One-off $10/Tb. Upload is through desktop browser of mobile app though, so definitely a convenience impact. For cold storage however it works brilliantly.
I would not recommend using WD’s privacy or security features, especially for anything cloud-facing. Over the years their drive and cloud products have had numerous security problems which they have been slow to correct (nearly always after someone else finds them for them).
Aside from that they’ve been very slow with updates. MyCloud was not supported on Catalina until late October last year, and even then users had connectivity problems going well into 2020.
I think another version of @tjluoma’s idea is to think about another device in between you and the cloud. He proposes a remote mac, but it could also be a NAS device located elsewhere in your dwelling – with its back up being Backblaze B2 or whatever.
In doing so you solve the problem of offsite back up AND the problem of more real-time file availability.
The latest of those articles is from 2018 so maybe they’ve tightened up things, so I wouldn’t throw away the MyCloud, but I’m just uncomfortable trusting my data given their history. If I were looking for an easy, lightweight server I’d probably get a consumer-level Synology NAS. They have affordable 1-bay & 2-bay units starting at $99 (before adding a drive).
Something like the 1-bay DS118 sells for $180 (without drive) and can serve files, transcode video, stream to your TV, back up your devices, etc and uses QuickConnect for easy-peasy secure access over the internet.
NAS units are designed to work on a network, not direct-attached, but you can connect by cable by assigning an IP address within your own network. For detailed info Google adhoc ethernet to mac synology, but this article might be helpful.
There are a handful of QNAP models of NAS which offer both network and direct attached storage (DAS), but I’m not familiar with QNAP.
Also, QNAP hasn’t been having a good year, security-wise.
You can do the reverse very easily – store the files you want on the Synology, mount the network drive on the Mac and keep the connection alive via an app like AutoMounter (available on the MAS). In effect, that’s going to do the same thing.
I have most of my data on my synology and back that up through their hyper backup solution to the Synology C2 service. I have 1TB over there and pay $60 for that. I can choose where I store the data and Hyperbackup fully encrypts it before sending it over.
I also have the 2TB icloud plan for the family, and the most important data from that goes to my synology (through Resilio Sync) to be backed up directly to C2.
So, in my case it’s 1 “live” solution: iCloud + 1 “Cold storage” solution: C2.
And since my Synology holds most, if not all of my data, I also have access to that everywhere through the Synology Drive app.
