arq_restore VS BorgBackup

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.

i use - and recommend - "borgbackup": for example with the "vorta" graphical frontend

I used this many, many years ago but switched to Borg[0] about five years ago. Duplicity required full backups with incremental deltas, which meant my backups ended up using too much disk space. Borg lets you prune older backups at will, because of chunk tracking and deduplication there is no such thing as an incremental backup.

Currently, I'm auto-backing it up with borg (push mode) through wireguard tunnel to NAS behind ISP's CGNAT. The borg takes care of deduplication in SQL file, so incremental update (even in append-only mode) is very small for PostgreSQL dump.

Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done).

Does anyone know how Borg 1.x and 2 would compare to Kopia?

You could use borgbackup.
