Although yes I develope and design at home, this is not the reason that made me apply my backup strategy. The reason is that you cannot trust security software, even if layered, 100%. So if you want real security for data and machines, you cannot avoid often images and backups. If the last known image is one month old then be sure that you'll lose things. If you have the time to reconfigure things and figure out what you have lost, then that strategy could be ok too. I have not said that any other strategy is not good. I have only said that security wise if you want to be safe you must have really recent images and real time synchronization ( for some data versioning is also absolutely needed ). For sure everyone knows better his needs. Images are saved on a linux machine too, that does only that job ( I mean backup of data and images ). Please tell me how this machine will ever get infected. That machine is 24/7 on and it's not the only place I store images.
