(description
|

"Rdiff-backup backs up one directory to another, possibly over a network.
|
||
The target directory ends up a copy of the source directory, but extra reverse
|
||
diffs are stored in a special subdirectory of that target directory, so you
|
||
can still recover files lost some time ago. The idea is to combine the best
|
||
features of a mirror and an incremental backup. Rdiff-backup also preserves
|
||
subdirectories, hard links, dev files, permissions, uid/gid ownership,
|
||
modification times, extended attributes, acls, and resource forks. Also,
|
||
rdiff-backup can operate in a bandwidth efficient manner over a pipe, like
|
||
rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up
|
||
to a remote location, and only the differences will be transmitted. Finally,
|

(description "Restic is a program that does backups right and was designed
|
||
with the following principles in mind:
|
||
|
||
@itemize
|
||
@item Easy: Doing backups should be a frictionless process, otherwise you
|
||
might be tempted to skip it. Restic should be easy to configure and use, so
|
||
that, in the event of a data loss, you can just restore it. Likewise,
|
||
restoring data should not be complicated.
|
||
|
||
@item Fast: Backing up your data with restic should only be limited by your
|
||
network or hard disk bandwidth so that you can backup your files every day.
|
||
Nobody does backups if it takes too much time. Restoring backups should only
|
||
transfer data that is needed for the files that are to be restored, so that
|
||
this process is also fast.
|
||
|
||
@item Verifiable: Much more important than backup is restore, so restic
|
||
enables you to easily verify that all data can be restored. @item Secure:
|
||
Restic uses cryptography to guarantee confidentiality and integrity of your
|
||
data. The location the backup data is stored is assumed not to be a trusted
|
||
environment (e.g. a shared space where others like system administrators are
|
||
able to access your backups). Restic is built to secure your data against
|
||
such attackers.
|
||
|
||
@item Efficient: With the growth of data, additional snapshots should only
|
||
take the storage of the actual increment. Even more, duplicate data should be
|
||
de-duplicated before it is actually written to the storage back end to save
|
||
precious backup space.

"ZBackup is a globally-deduplicating backup tool, based on the

ideas found in Rsync. Feed a large @file{.tar} into it, and it will

store duplicate regions of it only once, then compress and optionally
|
||
encrypt the result. Feed another @file{.tar} file, and it will also
|
||
re-use any data found in any previous backups. This way only new
|
||
changes are stored, and as long as the files are not very different,
|
||
the amount of storage required is very low. Any of the backup files
|
||
stored previously can be read back in full at any time. The program

is format-agnostic, so you can feed virtually any files to it.")
