Rsync works quite well on both Linux and Windows. I use it to back up my lab computer (XP), my work computer (Vista, unfortunately), several family computers (XP), and my primary Linux system. There's an excellent bit of freeware, Delta Copy, that provides rsync for the Windows side, either on command or via scheduled tasks. Another big benefit of rsync is that it does intelligent backups, only backing up what's changed. BTW, a raid array is a really good idea, too. I back up everything from the primary Linux box to an Infrant/Netgrar ReadyNAS 1Tb raid 5 box, also via rsync. Bill Ezell ---------- They said 'Windows or better' so I used Linux.

I have most of my important data in 4 places: two web sites, main 250 GB hard drive and external 500GB Western Digital USB Hard Drive (highly recommended). What I call "important data" is about 30 GB worth of stuff that is typically copied in all 4 places. The problem is keeping everything in sync. Syncing between two local resources (main hard drive and USB hard drive) is not too hard, considering the transfer speed that can be achieved, but mirroring the web resources is a pain, partly because of speed and partly because of OS differences in file name rules (Windows/Linux). I have not found the software I wanted (only looked at free/cheap stuff) so I am considering writing my own (Visual Basic). If anyone has suggestions for free/cheap commercial or FOS software to sync via ftp (Windows <-> Linux), I'll be glad to hear.

Disks are cheap. Many years ago, one of the guys I worked with pointed out to me/us that it was cheaper to buy more disks than it was to pay us at our normal sallary to figure out which bits should be saved. You can do a lot of handwaving in that area, but that's the general idea. My straw man for low cost backup is a USB disk. I'm thinking of a real rotating disk rather than the typical flash "disk". The key idea is that after you pull the cable, your system can't trash the bits. That is neither software nor fat fingers will delete anything. It isn't perfect, but it's close and simple. Any interesting bits should be backed up multiple ways. If any time-nuts have bits that aren't (well) backed up, please contact me off line so we can work out some way to add another backup copy to the system. -- These are my opinions, not necessarily my employer's.
