Balsa 1.7 includes a program to easily back up the Balsa user's data --EasyBackup 1.4
EasyBackup comes pre-configured for the typical Balsa user, but the documentation for EasyBackup isn't available on a running Balsa system. This is due to a bug that will be fixed in the next release of Balsa, You can download it (about 1 megabyte) now: Easy Backup User's Manual.
It's also available on a Balsa card/image that has never been run. It's in the .zip file:
/var/tmp/EasyBackup/EasyBackupLinux.zip
 Within that zip file the document is /Docs/User/UserManual.pdf
