I should add that my ping to a local server is 14ms, download is 82Mbps and upload is 30Mbps so the dire ping is going from UK to US.

I know this is an old thread but I also have this issue. I have 100+GB of stuff I want to exclude and purge from the backup. Too difficult to go file by file. It would be easier to create a parallel plan and start a new backup and once complete delete the old one. Not the nicest solution. Is there not a better option?

Just did a bit of reading and apparently id uses MD5 checksums although a couple of posts I read say this did not appear to be working - albeit that post was a couple of years old. So, will MD5 consistency checking happen in B2 (assuming I schedule it to run - which I have). And if run, will it pick up all corruption situations?

Sorry, not in front of the computer in question at the moment so maybe I have my terminology wrong. I believe that a 'consistency' check or something similar can be run. Presumably this tries to verify that what is uploaded is all present and correct and not corrupt. How does this work? Does it compare hash values or something? Does it actually download any files for consistency checking? How big an overhead is this?

Thanks for the quick reply. Sounds like block is the wrong choice for me. Shame about SFTP as this was going to be free storage for me :(
