+# backup
+
+this is a simple backup setup that I use on my home server
+
+`conf.d` contains files that have file glob lists in them, like `.gitignore`
+files. `./run` then runs restic for each file in `conf.d` and backs up the file
+list under the tag of the file name. if a file with the same name as in
+`conf.d` exists in `pre.d` it gets run before restic, and the same goes for
+`post.d` but it's after restic. `env` contains environment variables for
+restic, and gets sourced by `backup`.
+
+by default, only the last two backups are stored, and old ones get deleted.
+this can be edited in `forget`.
+
+systemd unit/timer files are included
