Terminology
===========
.. _deduplication_def:
Deduplication
Deduplication is a technique for improving storage utilization by
eliminating redundant data.
.. _archive_def:
Archive
An archive is a collection of files along with metadata that include file
permissions, directory structure and various file attributes.
Since each archive in a repository must have a unique name a good naming
convention is ``hostname-YYYY-MM-DD``.
.. _repository_def:
Repository
A repository is a filesystem directory storing data from zero or more
archives. The data in a repository is both deduplicated and encrypted
making it both efficient and safe.
Key file
When a repository is initialized a key file containing a password
protected encryption key is created. It is vital to keep this file safe
since the repository data is totally inaccessible without it.
