↳ In-reply-to » @mckinley My process hasn’t changed. (But the Gopher hole is gone. Here’s the file from 2023: https://movq.de/v/72fddfd8fe/2023-05-31--backups.txt )

Ran a few tests.

Copying data from the NAS’s encrypted ZFS pool to the USB disk’s encrypted btrfs runs at ~20 MByte/s. That is for a single 1 GB file of random data. Cold caches, sync included.

That same USB disk with the same btrfs can sustain ~75 MByte/s when I use it on my workstation (i7-3770).

And indeed, the aes flag does not show up in the output of lscpu on the NAS.

I’ll try to tweak some things about this, but it might be time for an upgrade … 🫤 (Or I’ll have to re-think the entire thing somehow.)
