A Windows executable is available here. This again requires the file p2x561.dll.
Usage:
LJBACKUP.EXE --user=<LJ username> --pwd=<password> [--month1=<start month>] [--year1=<start year>] [--month2=<end month>] [--year2=<end year>] [--file=<file name>]By default the tool will backup your posts for the current month only.
If you want a nice GUI, etc., you are better off using
orona_red's tool.
