Can I exclude files or directories from the backup?

Yes, you can. Since our backup is based on rsync, you can use rsync filters to exclude files and directories.

To exclude a directory, place a file called .rsync-filter in the directory, with the following contents:

+ .rsync-filter
- *

If you need to exclude certain files, for example compressed logs from /var/log, place a file called .rsync-filter in /var/log:

- *.gz

You can find more examples in the rsync manpage, under the FILTER RULES section.
