I would love to understand what the specifics were. Backblaze's whole design is based on a "log format" where you really SHOULD be able to understand the diffs and exactly what occurred at what days and times. In other words, a complete, total, absolute history of everything that occurred is found both on your local system, and then (encrypted) on our servers.
What I mean by "log format" is that when a file is backed up, a line is added to what we call the "bz_done" files that says something like this:
+ /pictures/puppy.jpg
The "+" means it was added to your backup. Then if you delete that file later we don't REMOVE that line, we add an additional line to the very end of the log like this:
- /pictures/puppy.jpg
The "-" signs means it was removed FROM YOUR LOCAL DISK (but not yet from the backup). Then 30 days later, the final line might appear like this:
x /pictures/puppy.jpg
That means the "30 day roll back history" period has expired and the file has been cleaned up from the Backblaze datacenter.
The whole point is we can determine exactly what occurred at what times, and you can understand the diffs yourself.
