Wouldn't it be useful if Veeam could actually "wizardise" the process so that it controls every aspect of the task, including perhaps creating some sort of checksum or similar for the final file being transported, such that the whole calculating digests process would no longer be required as it can guarantee that the contents of the file haven't changed?
I'll add that I'm no expert in such matters, just someone that finds myself occasionally needing the functionality so would love for it to be quicker
