Just a heads up, I recommend that you wait a few days until restic 0.17.2 is released. It is just waiting for some administrative factors and will be released any day now.
That release contains a fix for the problem mentioned here: Errors found by check: (1) Invalid type "irregular" (2) ciphertext verification failed - #2 by fede (PR here: backup: fix handling of files with type irregular by MichaelEischer · Pull Request #5057 · restic/restic · GitHub)
Even if you were to run or have already run restic 0.17.1, you can always fix the issue once you have restic 0.17.2, so don’t worry about it either way.
