That's nice for drive, but doesn't include any photos/video in photos.google.com.
So basically you have a single google storage pool that's reported at the bottom of the gmail.com interface. But now you can't use any of the google drive related tools to see what is consuming all your storage.
The photos.google.com is time based, so it's very hard to see what your largest files are.
Here are the steps for restore (although they can be terse)
1. Install Backup and Sync on new computer
2. Add an empty folder "Temp" to backup
3. Let the folder be backed up so that a Computers > My New Computer > TEMP is created on the cloud.
4. Go to cloud and move the top level folders in Computers > My Old Computer > Documents/Downloads/etc into Computers > My New Computer
5. Create empty folders with the same name on the new computer.
6. Add them each in the Preferences. In version 3.36+, the application will recognize that it exists in the cloud. It will then tell the user it will merge the folders.
It's tucked away at the end and without a checkbox like other items in the same view. Indeed, it looks at first glance to be informational.
Someone in the UX team may have thought that they were being clever, but like the W10 'cancel means upgrade' debacle, it'll cause trouble.
I do hope that this is just unfortunate design and that USB item is only enabled if the checkbox above it is on also. Perhaps I'm just having a bad hair day: I don't normally do conspiracy theories.
It doesn't take anything away from the current Google Drive client. It adds more features such as adding more folders to sync, choosing whether the images in those folders get synced to Google Photos, adding USB media support, and deletion options.
It also has a lot of bug fixes over the older client.
