Hi. I have a small network at home consisting of one wired, always-on F8 desktop (mine), a roving Mac laptop running OS X, and a rarely-on Windows XP laptop. The laptops are wireless. I also have a new 500 GB external hard drive that some of you may remember. The Mac user was thinking about getting a drive for herself to do backups using Time Machine or whatever Apple's backup app is. But we figured there ought to be a way to backup to my desktop/hard drive. I looked around and found BackupPC. It sounds like it'd do the job, if I could figure it out. (I'm having trouble discovering the Mac on the network [doesn't respond to nmblookup], and I have a feeling if I can get past that, I will have additional trouble getting rsync or tar to work there....) I thought I'd check here to see if there's anything else out there that would work. Ideally, it would be transparent to the clients, automatic when they're on the network, incremental.... You know, um, everything BackupPC does! Free and open source would be best.... Thanks, Reid
