Package backup
--------------

Downloaded files can be automatically saved in a separate directory for backup purposes. This feature is useful for tracking download history and ensuring that packages are available in case they are no longer present in the official software repository.

To enable automatic backup, add the following lines to the `gsm.conf` file or enable the feature during setup:

.. code-block:: bash

   backup_package_enable = [True/False]
   backup_package_path = /home/data/gsm/backup

The backup directory has the following substructure:

.. code-block:: bash

   │
   └── module
       ├── version
       │ pkg-filename.tar.gz.1734436688      # Package file
       │ pkg-filename.tar.gz.dsc.1734436688  # Package description file
       │ pkg-filename.tar.gz.sig.1734436688  # Package signature file
       ...
   ...

The creation time of the downloaded package file is used as the reference time for the backup. The timestamp is in UTC and is appended to all files.

Here is an example of the backup structure:

.. code-block:: bash
