winrar for incremental dvd backups

[TanisHalfElven]

i use winrar to backup all my files onto a dvd.
so far i had only static files (once made do not change) but now i need to backup up files that change frequently.

can winrar do the following
1. creatye a backup of my documents (or any other folder) in backup1.rar
2. next time backing up compare what is in backup1.rar and see which file are new or have been modified. then create a archive with only these files. create file backup1_2.rar (imaginary names)
3. third time look in both 1st and 2nd file and backup only the new or modified files.

if so please tell me how.
help appreciated.
