 === Restic ===
+  * Create a Restic repository in the current folder: <code>restic init --repo .</code>
+    * Note that encryption **and** password are mandatory, [[https://github.com/restic/restic/issues/4326|because]]. However you can store the password in a file in the repository, or use the a password file with ''--password-file''.
+  * Create snapshots: <code>restic --repo <repo> --verbose --compression auto backup <path></code>
+    * The chunker cannot be configured, contrary to Borg. It is equivalent to [[https://restic.readthedocs.io/en/stable/100_references.html#backups-and-deduplication|19,23]],[[https://restic.net/blog/2015-09-12/restic-foundation1-cdc/|21,512]], similarly to Borg's default [[https://borgbackup.readthedocs.io/en/stable/internals/data-structures.html#buzhash-chunker|19,23,21,4095]], but unlike my chosen values.
+    * ''--compression'': unlike Borg, there is only choicies ''auto'', ''max'' and ''off''
