"Clonezilla
"Clonezilla is an open source clone of Symantec Ghost Corporate Edition. It is based on DRBL, Partition Image, ntfsclone, partclone, and udpcast that will allow you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many computers simultaneously.
"Duplicity
"Duplicity backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity uses GnuPG to encrypt and/or sign these archives, they will be safe from spying and/or modification by the server."
