Understanding Backups

See screenshot attached
I am struggling to understand what I’ve done to create redundant backups.

The screenshot shows 3 copies of the same file, each within a diff path. To be clear, this file only existing on my pc in one location, yet I have 3 copies in my backup.

Any help understanding why my backups are working this way is much appreciated.

Also, what is the long string starting with “yzk…” That WD backup creates?


Thanks very much
