Hi I have run this on a Backup made with ADB through TWRP Backup, but I´m not sure if is running, my lap sounds like it is working a lot ... I can see a new .tar file with almost the same size of my document, but the script keeps running, after a while I close de cmd windows and explore the .tar but there is just 1 file named backup.... the same size of the original.

@DyKey13 The file is expected to be almost the same size. It should be pretty much exactly 16/(512+16)*100 = 3.03 % smaller.
It may help to look at both the input and the output file with a hex editor to understand what's supposed to happen and check whether that's working.
