In Expert Mode, you can adjust the quality of compression of the backup data.
Move the slide bar between Low and High to specify the quality of compression.
The higher is quality, the less space the backup file/-s will occupy on the storage media, but the more time it will take to compress.
If you choose to compress data, you also need to decide if you want to compress all data to a single zip file or to create an individual zip file for each selected file and folder. Check respective radio buttons to choose between these two options.
As for the encryption, you can encrypt the data with the 128-bit blowfish encryption method. Blowfish is a symmetric block cipher that takes a variable-length key, from 32 bits to 448 bits, and is ideal for domestic and exportable use.
