(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.
