Read =A716.12 (Backup Basics) in the FreeBSD Handbook. You'll find the English version in /usr/share/doc/en_US.ISO8859-1/books/handbook/backup-bas= ics.html. For full backups dump(8) and mt(1) seem to be the tools of choice. If you use dump and you want encryption, you could pipe the dump output through openssl to encrypt it with e.g. the AES algorithm with a 256 bit key. Run 'openssl enc -help' to see the encryption algorithms available. All the tools mentioned above are available in the base system, which is a prequisite for restoring system partitions in my book. My own backup strategy is to write dumps or /, /usr and /var to an external USB harddisk or DVD, for an easy restore. For large data partition= s I prefer to rsync(1) to a geli(8) encrypted partition on an external harddisk, because it is faster and more convenient than a dump.
