There is a risk involved when using any type of electronic storage for important or valuable data, e.g. photo's
I learnt the hard way, having "lost" 40 years worth of family photo's when the hard drive on my computer packed in.
Luckily, 6 months previously, I had backed up all my music, photo's etc. to a usb hard drive, and having sorted out the hard drive problem,
I was then able to transfer the lost files to the new hard drive. As double protection, I also backed up the files to a usb pen drive.
The only lasting result of this hard drive failure was the loss of the photo's from one holiday.
I learnt the hard way and invested in a personal cloud device, which has served me well so far.
I take the point, previously made, that a home network could be prone to cyber attack if passwords are left at default settings, but then it is up to the user to make sure
that the passwords are not left at default, which will go a large part of the way to defeating a hacker.
As I said at the beginning, no method of electronic storage is 100% reliable and safe ; the only thing that can be done is to reduce the risks by multiple storage methods.
Handing over $100's of dollars to people who then have you "by the short and curleys" is not the answer.
