Thanks in advance,
Sorry, but ext3 does support differential backups with lots of different backup software. Tivoli Storage Manager, Netbackup, Networker, and Arkeia, all support it. However, WINDOWS files on an EXT3 system, don't support what Windows considers an 'archive' bit.
Your question is a bit vague...are you running this software on the Windows system, or on the Linux server? Because you could attack this one of two ways:
1. Format a partition/drive on your Linux server as ntfs, so the Windows servers will have an easier time mounting and dealing with it. Linux can still mount and use it fine, using the ntfs-3g option.
2. If you keep the partition/drive as ext3, back it up using Linux software. Differential backups should work, as the files will be 'regular' linux files, on a native partition.
