@ramzii
this problem usually happens when BackWPUp uploading backup file to Dropbox, and during this process, a network problem happens and Dropbox returns error file size not correct.
Please try again to see if it’s work!

[Just a note]
We have a beta testing program now, please subscribe in here to become a beta tester if you want:

The beta version comes with automatically restore and many other enhancements.
Thank you!

Same issue here. Exactly the same two warnings and errors mentioned above.

@epistates,
is your problem happened sometimes or always?

@ramzii
