Backup script for tumblr using tumblr4r.
Adds a Backup subclass of Tumblr4r's Site class that makes backups of posts as well as images (for photo and regular posts)
Outputs to Jekyll-inspired plain text files with YAML metadata in the front matter. To substitute a different backup method, you'd have to change write_file as well as get_existing
Dependencies: tumblr4r, sanitize.
Use like this:
site = Tumblr4r::Backup.new('blogname.tumblr.com')
site.backup_path = "/path/to/your/backups"
site.make_backup
