Overview

Bash script meant to back-up full size localy from multiple location / device and upload a 2048px copy to google photo to leverage online album creation.

Back-up process :

1. Import location could be mounted sdcard or a network folder in sync your devices photo with some sync app (qnap / synology ...)
2. Photos will be imported (moved) to the photo_root directory like this <photo_root>/<year>/<month>/<day>/<original_name.jpg>. This scheme should avoid a lot of name conficts if using many devices but there is no garantee.
3. Photos will be resized and stored with the same exact scheme in photo_resized_root. Resize is done with imagemagick following this amazing blog of David Newton.
4. Photos will be uploaded to google photo into the Auto Backup album and a copy of the .xml response of the picasaweb api is kept next to the resized image.

Those .xml file are the only way to get back all yours photos from google photo if needed.

Choice have being made to work with no db / no index / no nothing.
