Unison has been an indispensable tool for me for many years. I keep my desktop and laptop in sync by using an always-on Linode as a sync server. Something I love about Unison is the fact that I can sync files from anywhere on my filesystem without having to move them or replace them with symlinks. I can also sync subsets of my files by defining multiple profiles. I have Unison set up to default to a "common" profile that includes nearly everything, but I can explicitly request a sub-profile if I want. I also have a separate profile that syncs the profiles themselves, so I can make profile changes on one machine and run `unison profiles` to upload them.
