In fact several hosts may use the same repository to backup directories and
files leading to a greater de-duplication.
You can exclude folders and files by specifying exclude-patterns.
Either specify them with multiple `--exclude`'s or one `--exclude-file`

# exclude go-files
*.go
# exclude foo/x/y/z/bar foo/x/bar foo/bar
foo/**/bar
$ restic -r /tmp/backup backup ~/work --exclude=*.c --exclude-file=exclude
Patterns use [`filepath.Glob`](https://golang.org/pkg/path/filepath/#Glob) internally,
