Can someone please put the situation in Linux with not filtering /var/log/lastlog (sparse file) somewhere in the docs or the wiki. It comes back to bite me every few years and I waste a bunch of time figuring out why rsync keeps aborting.
It's very powerful and customizable.You could do almost every scheme of backup. It works very well for notebook in a DHCP environment. It saves a lot of disk space. Works very well (with CYGWIN) on Windows environment through rsync daemon. The email feature it is really good and useful. Sadly, it's not enough user-friendly, lacks of backup progress indicator and there is not a easy and secure way of launch backup jobs from the client without login in to the server.
