So if you've got a Mac, test it out before you ever need it - try downloading a folder or group of folders that have lots of small files and totals 50-60gb, and see if it changes your file names. I worked with Backblaze and we came to the conclusion above - that it's just a difference between Backblaze's implementation of 'zip' and macOS's implementation of it. When I tried to unzip files that were up to the maximum size Backblaze allowed, the file names were replaced with seemingly random encoded letters, like "%A3". The restore was extremely painful - there's a size limit for zip files, so you have to choose groups of folders that's fine (as long as you make a note of where you got to!) - but there's a difference between how Backblaze makes zip files and how macOS unzips them. I've done a huge restore from Backblaze personal - I got a new Mac Mini and decided to restore all my personal files.

Backblaze B2 is S3-compatible, has been very reliable for me, and is pretty much the cheapest solution for volume storage. It will supports several targets, including S3-compatible services. It will backup your apps, configurations, and data. If you want a real backup, you'll want to use Synology's HyperBackup.

You'll have to do some major contortions to figure out a solution.
