arq_restore VS rclone

There's also Arq Backup which can backup to OneDrive so if you have less than 1TB to backup you might not need to pay anything.

I use Arq Premium backup services They supply the backup software and the cloud storage

People who want something similar may want to look at Arq [1]. Similar to restic, it provides incremental encrypted backups to most cloud providers (or a machine with SSH). But it is a Mac app, making it easy to configure and maintain. I never had issues with data corruption so far.

Disclaimer: I am not affiliated with them, just a happy user for 9 years.

Sending it to the NAS should create a copy automatically to BOTH an online server (I was thinking dropbox, but the space might be too limited. Maybe AWS? I've used https://www.arqbackup.com/ on my computer before so something similar would be great) and a second drive (so I guess I'm looking at a 2-drive NAS that I can setup as master-slave).

For actual off-site backups, using something like https://www.backblaze.com or use https://www.arqbackup.com and your own choice cloud storage provider.

Curious too. On the Mac side, I feel like I mostly hear about Backblaze for cloud backups, but I do like Arq for pushing to any of the typical cloud storage options.

Have a look at Arq backup https://www.arqbackup.com/ It might meet your requirements

Take a look at Arq Backup - not identical, but it's E2EE.

You could try this: https://www.arqbackup.com/ , it supports B2 I believe.

Regarding Arq backup: if you are worried about using a proprietary (enrypted) and closed-source backup format in case the company were to go under, they have an open source command-line restore tool:

I've been using Arq for years, but I need to look into the "Glacier Deep Archive" format which is about 1/20th the cost of the fastest storage class.

rclone: a command-line program to manage files on cloud storage.

Synchronise buckets with Sclone or Rclone

Says that Apple doesn't provide a multi platform API. It doesn't provide any official supported way to access iCloud from Windows, Linux.

There's a ticket covering everything you might ever want to know:

seconding rsync and syncthing.

the server could expose an smb or nfs share, the client could mount it, and then sync to that mount.

rsync over ssh also works, if you do not want to run smb/nfs.

this is also a cool tool https://rclone.org/

rclone [1] to dropbox. works since years without problems

rclone provides a special pCloud config option, which makes the setup straight forward. rclone can encrypt the data it uploads with its own encryption but not with the pCloud encryption. Therefore it can only upload data to the unencrypted pCloud folders, not to the Crypto Folder.

The arkclone project impliments rclone in ArkOS to achieve cloud saves. Not yet built in to ArkOS yet, and not a lot of recent traction on the pull request to get it added, but it can be installed manually.
