On Linux and BSD systems, backups and restores in TAR or EXT formats can be done via FTP as well as SSH, RSH and to local files.
---- Changes since 1.320 ----
Added a warning if % is used in filenames but strftime substition is not enabled.
---- Changes since 1.390 ----
When making tar format backups on Linux, an option to just append new files to the archive instead of over-writing it is available.

<header>Just add new files to archive?</header>
When this is set to <b>No</b> (as it is by default), the backup destination
will be replaced with an archive of all files currently in the source directories. But if you select <b>Yes</b>, only files that have been changed since the
archive was create will be appended to it. This is useful when making incremental backups. However, it cannot be used with compressed or remote archives. <p>
