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

		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

		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

mkdir -p ~/.config/borgmatic && generate-borgmatic-config

sudo mkdir -p ~/.config/borgmatic && sudo generate-borgmatic-config -d ~/.config/borgmatic/config.yaml

sudo nano ~/.config/borgmatic/config.yaml
