I have a Macbook and I need an incremental backup solution over WiFi. Time Capsule or AirPort Extreme with attached HDD is perfect fit. But I want to find cheaper solution if exist.
How about Mac mini? I thought about Mac mini with only internal disk but has separated backup partition. Can I get Time Machine backup over WiFi with only Mac mini? If you have used this, please let me know whether it is possible and how it is reliable.
Or any other recommendable solution is exist, please let me know.
Direct attachment of some external HDD to Macbook is not an option, because I think I will forget attaching it very easily, so it won't effective to me. Backup disk should be connected to my Macbook automatically when I connected my home WiFi network.
