Windows Local Backup
---------------------

Windows local backup system. Supports anything Sqlite3 supports.
The bundled TCC is designed for Windows XP.

Backups are stored in a SQLite database. Each backup is timestamped
at the time of execution, with an optional name.

Each file in the backup has it's SHA256 sum included. If a file has
an identical SHA256 sum, only one copy of the file is stored. The
relative directory of each file is stored.


-----------
Compilation
-----------

First you need to set up TCC.

1. Install TCC.
2. Download https://sourceforge.net/projects/mingw/files/MinGW/Base/w32api/w32api-3.14/
3. Copy the ``include` directory of this into ``tcc/include/winapi``.

After that, run ``compile.bat``. ``wlb.exe`` should be ready to run.

-----
Usage
-----

``wlb.exe`` executes each argument to it in sequence. Most of the time
you will run ::
    wlb.exe \V \D dbname.wlb \A dir1 \A dir2 ...

``\V`` turns on verbose mode, which reports the name of each file
as it is being read. You can remove this to make WLB only report errors, or
you can use ``\VV`` to turn on debug mode.

``\D`` denotes the name of the database. This must come before all archive
commands. There can only be one ``\D`` specified per run. If specified file
does not exist, it will be created. If the file is a SQL database whose user
version is not a supported WLB version, the program will report an error and
close.

``\A`` requests WLB to archive a file or directory. If what follows is a
directory, then WLB will archive every file under the directory, and in the
directories under that, etc. There can be multiple ``\A`` commands corresponding
to different files/directories.
