Data To be Copied only When Hash is different #277

Closed LobevaMD closed 5 months ago

LobevaMD commented 5 months ago

Question Describe your question. I am currently transferring Dozens of TB of Data. One of the Commom erros I have is "Size is changed(dst_digest)" Verify DST read error. I then noticied that the size and dates of the files I copied are the same but the hashes are different,

Is there a way to verify xxh3 for the source and target as quickly as possible, and only copy (overwrite) the ones that dont match?

the same but the hashes are different,

That's strange. Please paste all log data for that file. If it is displayed an "Size is changed(dst_digest)", the file will then be renamed/dated to 1980/deleted, etc., depending on your verification settings. (unless you have selected "No action" in the settings)

For example, "rename to .fc_verify_err" is selected in the settings, it should be display a log like the one below.

Size is changed(dst_digest) : <file name>
Verify dst read error in and it was renamed (.fc_verify_err) : <file name>
