Duplicity
Duplicity incrementally backs up files and directory by
encrypting tar-format volumes with
GnuPG and uploading them to a remote (or local) file server. To
transmit data it can use ssh/scp, local file access, rsync, ftp, and
Amazon S3.
Because duplicity uses librsync, the incremental archives are
space efficient
and only record the parts of files that have changed since the last
backup. As the software uses GnuPG to encrypt and/or sign these
archives, they will be safe from spying and/or modification by the
server.
Currently duplicity supports deleted files, full unix
permissions, directories, symbolic links, fifos, etc., but not hard
links.
The duplicity package also includes the rdiffdir utility.
Rdiffdir is an extension of librsync's
rdiff to directories; it can be used to produce signatures and deltas
of directories as well as regular files.
Features include:
- Simple to use
- Encrypted and signed archives (using GnuPG)
- Bandwidth and space efficient, using the rsync algorithm
- Standard file format
- Choice of remote protocol
- Local storage
- scp/ssh
- ftp
- rsync
- HSI
- WebDAV
- Amazon S3
