Incremental backups from Windows
I bought a Western Digital NAS device, which apparently runs on a self-contained linux OS. I have been backing up my two Windows PCs to each other using xcopy and the /d option has always worked fine. Now, however, the modified date doesn't seem to duplicate exactly on the NAS device and my incremental backups have become nearly full backups each time. I tried XXCOPY, but it didn't work and I hate to go to the GUI tools. I enjoy linux, but want to keep this NAS device a simple, mobile device requiring little or no maintenance on my part. I also cannot telnet to the device, so I don't think I can hack it.
Thanks in advance!
