+## Restore
+
+### From Snapshot
+
+When `dsnap-sync` did save the data using a native btrfs method
+(`btrfs-snapshot` or `btrfs-clone`), data will be stored in a snapper compatible
+directory structure on the target.
+
+The structure may look like:
+
+* └ backups
+   * └ @\<server-name\>
+	 * └ \<subvol-name\>
+	   *  └ \<subvol-id\>
+		 * ├ \.snapshot\>
+		 * └ info.xml
+
+To restore the data, you may either use `snapper` methods or copy back
+the needed files using standard OS tools.
+
+  * using snapper
+	You may use `snapper diff <id1>..<id2> [files]` to compare the differences
+	between the given suvol-id's.
+	You may use `snapper rollback <id> ` to restore all data from the given \<id\>
+
+  * using OS tools
+	Use your favorit file-manager and change into the directory storing your
+	target backup subvol-id. The snapshots are stored in **read-only** mode.
+	Data are presented flat file and can be copied to any desired destination.
+
+### From Tape
+
+When `dsnap-sync` did save the data with method `btrfs-archive`, you will find
+the corresponding data in a snapper compatible directory structure on the tape.
+
+The structure may look like:
+
+ * └ backups
+   * └ @\<server-name\>
+	 * └ archive-\<subvol-name\>
+	   *  └ \<subvol-id\>
+		 * ├ \<subvol-id\>_full.btrfs
+		 * └ info.xml
+
+The file `info.xml` provides the metadata corresponding to the snapshot.
+The data of the snapshot is stored in the file `<subvol-id>_full.btrfs`.
+This file has to be decrypted with btrfs tool `btrfs-send` to a btrfs
+restore directory:
+
+	cd /target_btrfs_path
+	cp /path_to_tape_root/backups/@<server-name>/archive-<subvol-name>/<subvol-id>_full.btrfs .
+	cat <subvol-id>_full.btrfs  | btrfs receive -v  .
+	rm <subvol-id>_full.btrfs
+
+Please consult btrfs-send man-page for further info.

-Description: Backup and synchronize btrfs filesystems
- dsnap-sync is designed to backup btrfs formated filesystems. It takes 
- advantage of the specific snapshots functionality btrfs offers and i
- combines it with managemnet functionality of snapper.
- . 
- dsnap-sync creates backups as btrfs-snapshots on a selectable target 
- device. Plug in and mount any btrfs-formatted device to your system. 
- Supported devices may be either local USB drives, but can be as well 
- remote accessible RAID drives. If possible the backup process will send
- incremental snapshots to the target drive. If the snapshot will be 
- stored on a remote host, it is secured with ssh.

+diese in einer `snapper` kompatiblen Datei-Struktur auf dem Band.
+
+Dies Struktur könnte so aussehen:
+
+ * └ backups
+   * └ @\<server-name\>
+	 * └ archive-\<subvol-name\>
+	   *  └ \<subvol-id\>
+		 * ├ \<subvol-id\>_full.btrfs
+		 * └ info.xml
+
+In der Datei `info.xml` werden die Metadaten zum Snapshot gespeichert.
+Die Bewegungsdaten des snapshots befinden sich in der Datei `\<subvol-id\>_full.btrfs`.
+Diese Datei muss mit dem btrfs programm `btrfs-send` auf ein btrfs Verzeichnis zurück
+geschrieben werden:
+
+	cd /target_btrfs_path
+	cp /path_to_tape_root/backups/@<server-name>/archive-<subvol-name>/<subvol-id>_full.btrfs .
+	cat <subvol-id>_full.btrfs  | btrfs receive -v  .
+	rm <subvol-id>_full.btrfs
+
+Die man-page zu `btrfs-send` enthält weiterführende Informationen.

 # Examples
 
+## Snapper configs cache
+
+To integrate already existing snapshop subfolders located on a given
+filesystem, you need to add the snapper config name to the config
+file. Then restart the snapper service to reread the config list.
+
+```
+[root@dwsbackup dsnap-sync]# cat /etc/conf.d/snapper
+## Path: System/Snapper
+
+## Type:        string
+## Default:     ""
+# List of snapper configurations.
+
+#SNAPPER_CONFIGS="root data.dwssrv1 home.dwssrv1 machines.dwssrv1 root.dwssrv1 libvirt.dwssrv1 data2.dwssrv1 lxd.dwssrv1 archiv2.dwssrv1 archiv3.dwssrv1 root.dwssrv2"
+SNAPPER_CONFIGS="root data.dwssrv1"
