ZFS claims that it can recover user error such as accidentally deleting of files. How does it work? Does it only work for mirrored or RAID-Z pool? What is the command to perform the task?
Also for COW, I understand that during the transaction (while data is been undated), ZFS keeps a copy of the previous data. However, once the transaction is successfully completed, isn't it the case that the previous data blocks are unreferenced and can be used by future writes? So there should be no guarantee that the previous data can be recovered.
