Apple desktop / laptop backup application

Hello DEVs, I need a small, light application that will backup a users data. This application will backup data from a list of up to 10 locations, encrypt / compress then upload to an offsite storage Icloud, Google Drive, Dropbox, etc. on a schedule. Application must be installable on user machine. Please feel free to ask any questions. Application that will start on boot, ready to backup. A GUI for the user to choose folder locations to backup, backup intervals, offsite drive login information etc. The app will use lossless compression and then encryption with a user selected key. Then the files would be uploaded to a offlite drive – Icloud, Google Drive, Dropbox, etc. The app will have an option to download a backup decrypt and decompress it to a selected file path. The app will also have an option to overwrite the last backup on every backup interval or keep the last x backups in the drive to eliminate storage space needed.
