Dear all

I need to backup a lot of data regularly from one of the PC in my workgroup to my own PC.
As data involve is huge, copying takes a lot of time.
Please let me know how I can syn only the new new changes of the folders in the network PC to my PC autmatically at certain time of the day?
Or is there a freeware that can do the job?
Thank you very much!

Jeff
