Outputs chunks in specified directory. You can configure it to write directly to tape, but it's not the best solution. > 3. Can be configured to write only N chunks and after that wait for SIGUSR1 to write next. > 4.

It takes approximatelly 30 minutes of my time and 6 hours of real time (i need to replace DVD's and write labels on them). It takes 12 DVD's and cost 6$. > > If you tapes is not very huge (< 4Gb) you will be better to use DVD's. Write once DVD is available ~0.5$ is you bought 100 at once. > DVD is more reliable then tapes, and you can just put old backups on the shelf for long storage. > For daily delta-backups you can use few DVD-RW. > > i have 100GB tape drive. thanks for your program!
