To save all your photos and videos to your Google Drive from your Windows or Mac computer or from your camera / phone / Storage cards, read below:
Back up your cameras, phones, & storage cards
If you choose to upload photos from your phone, camera, or storage cards in the set up, then every time you connect that device to your computer, the photos and videos on them will upload automatically (after prompting you the first time). Auto Backup uses your Google Drive storage and uploads at full size by default. You can change these settings any time in your Auto Backup Preferences.
Quick Tip Before You Automatically Backup Photos & Videos from Compuuter or Camera to Google Drive
Photos & videos are precious memories and all of us never want to ever lose them to hard disk crashes or missing drives. PicBackMan is the easiest and simplest way to keep your photos/videos safely backed up in one or more online accounts. Simply download PicBackMan (it's free!), register your account, connect to your online store and tell PicBackMan where your photos/videos are - PicBackMan does the rest, automatically. It bulk uploads all photos and keeps looking for new ones and uploads those too. You don't have to ever touch it.
