Google+ auto backup for desktop
Improvement: Preserve your original RAW files in Auto Backup, and you will also be able to download the RAW image once it’s been uploaded.
RAW upload for Auto Backup is opt out, as the setting will default to ON. You can change this setting: there will be an added checkbox in Auto Backup preferences with option “Upload full-size RAW files.” See attached image!
If the checkbox is on, RAW files are imported from memory cards the user plugs in.
Uploading full size or RAW (and any images larger than 2048 px) counts against your Drive storage quota.
Users will be notified of this change when they launch the new version of Auto Backup for desktop.
