borgmatic VS arq_restore

- for important files, a separate box where I have borgmatic [1] in deduplication mode installed; this is updated once in a while

Just curious: Do you have any reason to believe that such a data corruption bug is likely in ZFS? It seems like saying that ext4 could have a bug and you should also store stuff on NTFS, just in case (which I think does not make sense..).

Not really dumb. I do use them too but with Borgbackup on the top (since they support it natively).

I found Borgmatic ( https://torsion.org/borgmatic/ ) to be the best way to run my backups. It takes care of everything from pruning to verifying the checksum etc... and it integrates with some monitoring (like cronitor).

So Borgmatic + rsync.net is the best combo

For backups I use Borg myself. If you need a GUI, you can use Vorta or Pika. With borgmatic, there is also a wrapper that extends the range of functions of Borg.

Furthermore, Borgmatic is a wrapper for Borg that extends or improves the range of functions.

For those of you not familiar, borgmatic is a very convenient tool which runs as a wrapper around borg.

I recommend Borg and Borgmatic. Automated, easy to setup, capable of notifying you if anything happens, deduplication and compression makes backups smaller, etc.

To add to this, Borg backup can be a little daunting to configure. There is a wrapper script called Borgmatic that distills it down to a single yaml config file. There are also some cloud hosts like BorgBase and rsync.net with native Borg support.

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.
