+[[!meta title="Obnam backup program"]]
+
+Obnam is an **easy, secure backup program.**
+Backups can be stored on local hard disks,
+or online via the
+[SSH SFTP](http://en.wikipedia.org/wiki/SSH_File_Transfer_Protocol) protocol.
+The backup server, if used, does not require any special software,
+on top of SSH.
+
+Some **features** that may interest you:
+
+* **Snapshot** backups. Every generation looks like a complete snapshot,
+ so you don't need to care about full versus incremental backups, or
+ rotate real or virtual tapes.
+* Data **de-duplication**, across files, and backup generations. If the
+ backup repository already contains a particular chunk of data, it will
+ be re-used, even if it was in another file in an older backup
+ generation. This way, you don't need to worry about moving around large
+ files, or modifying them. (However, the current implementation
+ has some limitations: see [[faq/dedup]]).
+* **Encrypted** backups, using GnuPG.
+
+See the [[tutorial]], and below for links to the manual, which has
+examples of how to use Obnam.
+
+Obnam can do **push** or **pull** backups, depending on what you
+need. You can run Obnam on the client, and push backups to the server,
+or on the server, and pull from the client over SFTP. However, access
+to live data over SFTP is currently somewhat limited and fragile, so it
+is not recommended.
