+Archives and repositories
|
|
|
+-------------------------
|
|
|
+
|
|
|
+A *Borg archive* is the result of a single backup (``borg create``). An archive
|
|
|
+stores a snapshot of the data of the files "inside" it. One can later extract or
|
|
|
+mount an archive to restore from a backup.
|
|
|
+
|
|
|
+*Repositories* are filesystem directories acting as self-contained stores of archives.
|
|
|
+Repositories can be accessed locally via path or remotely via ssh. Under the hood,
|
|
|
+repositories contain data blocks and a manifest tracking which blocks are in each
|
|
|
+archive. If some data hasn't changed from one backup to another, Borg can simply
|
|
|
+reference an already uploaded data chunk (deduplication).
