Ask HN: What strategies should I consider for backing up my home NAS

3 points by delgaudm ↗ HN
I've recently acquired a NAS (QNAP, if that matters) to help manage the data my business generates - primarily video and audio files and projects. What strategies should I consider at the outset to make offsite backups reliably, affordably, and hopefully automated for this new device?

The 3-2-1 rule might be a good starting point: https://www.networkworld.com/article/3527303/for-secure-data...

That hits to the core of my question. How do I get 30 or 40 terabytes of data offsite in a reasonable fashion? Is Amazon Deep Glacier at about $400/year the way to go? (And then I have to figure out how to actually make that work.)

You can upload up to 96T using a Backblaze Fireball for $500.

With HashBackup (I'm the author) you would connect the Fireball to your network, setup the network shared directory as explained on Backblaze's site, and use a HashBackup "Dir" destination to create your backup. Then return it to Backblaze.

After the data is loaded into your B2 bucket, change the HashBackup destination type to a "B2" destination, add your B2 credentials, and you're done. The backup can now be accessed by HB as if it were uploaded directly to B2.

This is very helpful. Thank you!

Backblaze is great for cloud backups. They do not backup network connected drives but will backup drives connected locally.

I'm not pretending a network drive is local, but actually mirror the important data from my NAS to a locally connected 14TB USB drive. It stays connected all the time.

I have some cron jobs that run rsync scripts, but the data that needs to be backed up rarely changes. This gives me 30TB on my NAS, of which, 14TB are backed up in backblaze for $60/year.

I can make this work in my situation because the items I want backed up are less than the working space I want on my NAS.

My experience with backblaze has been dark patterns and and customer hostile practices. They get recommended in every thread about backups, and I started using them because of these recommendations. I’m not a customer any more and I wouldn’t use them again.

The GoDaddy of cloud backups for me.

Rather than accusing them of "dark patterns and customer hostile practices", list specifically what they did. I've had good experiences with their B2 service.

A first concern is how to actually secure it.

There have been numerous vulnerabilities, back doors, default passwords etc in Qnap products; search HN.

In some cases devices have been attacked with ransomware even in private networks (no ports were opened to internet) through UPnP.
