I'm slowly squeezing "sniglets" from our NUC based storage system and wish to learn from others using Kopia. Believe it uses the Blake2 hash for everything.
I have successfully restored drives with Kopia by checking the "skip any errors" box, but have experienced some unwelcome problems when performing hash verifications of existing backups. So far at least, those problems have been traced to equipment deficiencies which I am addressing.
Deduplication saves a lot of space. So I'm using Kopia for backups more and more. Our previous system used a hash based equivalent to Rsync (https://bvckup2.com/kb/delta-copying).
I trust Bvckup more - but Kopia's design allows deduplication of multiple drives and pools.
