"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
"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."
