Store images in zip files
I have a long history of time snapper images (about one and a half years of daily work) and I like to keep a backup of my timesnapper images. However because there are so many small files the backup process takes quite a long time because it checks all files for changes. It would be neat if the snapshots could optionally be stored inside an archive format per day like a .zip or a .tar file. Less files, faster backups.
