Ask HN: How do you persist your archived digital data for the long term?

I’m assuming you mean personal data, such as family photos? I store onto a local NAS, with offsite DVD-R of the important stuff.

Personally I still like writable disks as one copy, you can’t (within reason) hack or accidentally delete something that’s offline in a safe most of the time.

Archivebox.io output saved to a zpool with raidz2 where I rotate out bad drives as they fail over the years. Every 6 months I dump the whole folder to Amazon Glacier, and I have an off-site back up in another city that’s also updated less frequently.

Designed for long term storage, supports multiple storage backends and can replicate them.

For photos, print them and stow them away. Prints survive hundreds of years, if done right. This should not be the only strategy, though.
