Accessible cloud backup client?

Hi
I think ChronoSync supports AWS, and it's very accessible.

Arq Backup is what you want. Version 7 is (thankfully) back to a very accessible native UI. I run and rely on this for my Mac Mini file server/NAS.

Of course, any number of free and/or FLOSS CLI tools is also an option; of those I've used, restic is my preference. Be aware, though, that none of them can support APFS snapshots of the source volume prior to backup, because of the requirement of developers to seek consent from Apple for the entitlement to use that API (which is absolutely, definitely, purely about security, and not a block on innovation. Oh, no. No siree!). To be completely fair, though, Arq is genuinely good, and it's easier to do things like send emails when there are problems with direct support, instead of hacking something together with shell scripts that you run from launchd.

I like and use ChronoSync; it’s great. You can use it to make backups, of a sort, if you want, but it's really a synchronisation tool, not a backup program. It doesn't encrypt data, index it, compress it or deduplicate it, it just synchronises the contents of a folder hierarchy from one place to another place. That can include a cloud storage. If you want a tool that preserves information about files that is useful for restoration and versioning, though, you really want a program that records it in its own format, and makes it easy to find it for restoration, minimises time spent backing up, verifies integrity of backed up data, etc. that you expect for backups. So it depends on the level of provision you need. A simple tool that copies files or directories, or a full-fledged backup program. Arq is the latter, ChronoSync the former.
