Hello, I am hoping someone here can help find a simple and easy backup software suited for my needs. I have long stayed away from doing regular backups because I find it to be a pain as I never really figured out how to get different softwares to do what I needed. Please see the requirements below. I prefer not to use TimeMachine. Hopefully it is easy to understand but if there's anything I need to clarify, please let me know I'm looking for a software that allows backup/update of specific folders only, not the entire hard drive. An option to add new files and update modified files in a folder. (Instead of making 2 copies of the same file, just update the copy that's already backed up if the file has been modified) Option to retain files/folders on the External drive from a previous backup even though that file might be now deleted on the HDD. For example, if I have File A and B backed up on an external drive, if at a later time, I delete file Y from my HDD - when the software backs up again, I want it to retain file Y in the External drive even though it is deleted on the HDD. I had read somewhere that CarbonCopyCloner/SuperDuper is able to do the above but I am not very savvy with the program so if anyone can point me to a step-by-step guide or tutorial on how to do the backup as mentioned above, I would be really grateful. Thank you in advance.
