The new Google Photos won't automatically back up your What's App and Facebook image. There are several reasons why Google Photos can fail to do this, but I want to concentrate on one specific reason why you won't get automatic backups.
Google is making changes to how they store images, and it doesn't want to be responsible for backing up images on your computer. This means that if you use Google Photos, you need to know about the 'local disk backup' option. Here is what I mean.
When I first saw this and I started searching for 'backup,' the first thing that popped up was Google, which I know nothing about. I went and checked the Google help center to see if I could find any information or if I had to go to Google.com for more details.
The Google help center didn't have anything to do with the problem. The answer from their help desk was, 'it's not an option in Google Photos.' Why is this?
My guess is that Google understands that they will lose the latest images to be backed up every time you change your phone. They also know that you might lose your photos by deleting your phone. Now I get that Google wants to make the Photo Stream available everywhere, but I am not sure how they are going to handle this.
Google wants everyone to be able to use the Photo Stream, and that is their goal. But then the Google Photos can have a problem because they cannot back up your What's App and Facebook images, so you have to remember to download them all manually when you get a new camera. Is that really worth it to you?
Google wants to have the option available everywhere, but my guess is that they do not want to take the blame if someone loses pictures. So that means that they will have to do it on their own. That will make it easier for them, but for some people, it will make things harder because they don't know anything about it.
If you are going to be using Google Photos for your What's App and Facebook images, then you should be aware of this. It would be better for you to get a software program that can back up your pictures for you than relying on Google Photos to do it for you.
