On Windows: C:\ProgramData\Backblaze\bzdata\bzbackup\bzdatacenter\ You can find these files on your local computer here (please do NOT modify these files, it will destroy your backup and ability to restore):

In the example above it says "457" - that is the number of bytes that was uploaded. And just before the filename is the number of bytes.

At the far far far right of the line is the name of the file. Then there is a date of WHEN THIS OCCURRED, see how it starts with the year "2023", then the month "03", then the day "23", then hours=01, minutes=02, seconds=03. Then the "+" (plus) symbol means this file was added to your backup -> it was uploaded. You can interpret that line as the line version number "5" (all lines are this version number, but it allows Backblaze to change the format of the rest of that individual line later if and when it becomes line version "6". What is appended to the bz_done files is this: 5 + 20230323010203. Let's say you add a new file to your computer (or it changes) called C:\cute\puppy.jpg which is a picture of your puppy. So let's walk through a simple upload example to show how this works. This is what has been "done" to your backup. It starts like this: every single action that occurs is APPENDED to a log called the "bz_done" files. So there are no mysteries allowed, you can just look at this record and decide what occurred!!

The record of everything that occurred, when Backblaze uploaded each file, and you have a copy on your local computer, and it is pretty easy to read and includes the EXACT FILENAME and EXACT NUMBER OF BYTES uploaded. One of the coolest, most awesome parts of Backblaze is it never loses any history of what occurred. With Backblaze, you can just go view EXACTLY what was successfully uploaded, and the byte counts of every item. I can’t tell if things have legitimately changed Disclaimer: I used to work for Backblaze and wrote a lot of the client that runs on your computer.
