+Creare la key dal quale si vuole entrare con SSH senza login (x es 192.168.1.3)
+
+	ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "Coppia chiavi SSH di tuo nome"
+
+Copiarle sul client dove si vuole entrare (x es. 192.168.1.4)
+
+	ssh-copy-id orangepi@192.168.1.4

+
+Before a backup can be made a repository has to be initialized:
+
+	borg init --encryption=repokey /path/to/repo
+
+Backup the ~/src and ~/Documents directories into an archive called Monday:
+
+	borg create /path/to/repo::Monday ~/src ~/Documents
+
+The next day create a new archive called Tuesday:
+
+	borg create --stats /path/to/repo::Tuesday ~/src ~/Documents
+
+List all archives in the repository:
+
+
+	borg list /path/to/repo
+
+```sh
+		Monday                               Mon, 2016-02-15 19:14:44
+		Tuesday                              Tue, 2016-02-16 19:15:11
+```
+
+List the contents of the Monday archive:
+
+	borg list /path/to/repo::Monday
+
+```sh
+		drwxr-xr-x user   group          0 Mon, 2016-02-15 18:22:30 home/user/Documents
+		-rw-r--r-- user   group       7961 Mon, 2016-02-15 18:22:30 home/user/Documents/Important.doc
+		...
+```
+
+Restore the Monday archive by extracting the files relative to the current directory:
+
+	borg extract /path/to/repo::Monday
+
+Delete the Monday archive (please note that this does not free repo disk space):
+
+	borg delete /path/to/repo::Monday
+
+## Borgmatic Install
+
+	sudo apt install borgmatic
+
+poi si genera il file config
+
+	mkdir -p ~/.config/borgmatic && generate-borgmatic-config
+
+in questo caso il file è 
+
+	/etc/borgmatic/config.yaml
+
+altrimenti si specifica la dir con -d
+
+	sudo mkdir -p ~/.config/borgmatic && sudo generate-borgmatic-config -d ~/.config/borgmatic/config.yaml
+
+e si deve editare
+
+	sudo nano ~/.config/borgmatic/config.yaml
+
+```bash
+source_directories:
+    - /home/orangepi/Documenti
+exclude_patterns:
+     - /home/orangepi/Documenti/c
+repositories:
+    - path: ssh://orangepi@192.168.1.4/home/nvme/prova/miosudo.borg
