Yes, the :ref:`deduplication <deduplication_def>` technique used by |project_name|
makes sure only the modified parts of the file are stored.
Can I backup from multiple servers into a single repository?
Yes, but in order for the deduplication used by Attic to work, it
needs to keep a local cache containing checksums of all file
chunks already stored in the repository. This cache is stored in
``~/.cache/attic/``. If Attic detects that a repository has been
modified since the local cache was updated it will need to rebuild
the cache. This rebuild can be quite time consuming.
So, yes it's possible. But it will be most efficient if a single
repository is only modified from one place.
