Ask HN: What's your backup strategy for your small business?

I run a small backup company and was wondering how other businesses manage their backups (very meta).

I don't store data on customers' behalf, only download and transmit it to their storage of choice.

Currently, I have 3 levels of backups:

* hot storage - backups run every 5 minutes to Hetzner's Storage Box. if things go wrong, this is where I will first restore from.

* offsite #1 - Tarsnap, encrypts and deduplicates backups to S3. runs once a day in the evening.

* offsite #2 - Restic, encrypts and deduplicates backups to Backblaze B2. runs once a day, early in the morning.

anything you'd change about this setup?
