+git-annex can transfer data to or from any of a repository's git remotes.
+Depending on where the remote is, the data transfer is done using rsync
+(over ssh, with automatic resume), or plain cp (with copy-on-write
+optimisations on supported filesystems).
+
+It's equally easy to transfer a single file to or from a repository,
+or to launch a retrievel of a massive pile of files from whatever
+repositories they are scattered amoung.
+
+git-annex automatically uses whatever remotes are currently accessible,
+preferring ones that are less expensive to talk to.
