Transfer back up with less bytes
I always transfer/copy my backup to an external drive and it usually works fine. This time though, it is only transferring about half the files, yet the process says 100% complete. There must be a setting or something screwing this up. I have done it twice now with same effect. Why isn't it transferring the file with the same byte total?

I am just using file explorer. It always works, this time though, I only see 89 GB and the file from which I copied is 189 GB. I will try validating each of the files to see if they are both valid somehow. First time this has happened. There is adequate disk space on the back up file.
Not sure how to use the robocopy command you posted.

Rick, the robocopy d:\ f:\ /mir is fairly simple to use in a simple .bat file.
d: should be set to the source folder being copied from.
f: should be set to the target folder being copied to.
/mir tells robocopy to mirror the source folder contents to the target folder, including any deletions or additions of files.
See webpage: Robocopy and a Few Examples - for more examples of usage.

Thanks. Interestingly, the smaller file was validated. Odd.

When I went in to look at the file again, it had the correct size listed. Hadn't seen that before.
