For Linux machines you have to look hard to beat Rsync - it's very efficient and supports encryption and rate limiting. Sadly not too much help for Windows machines.

Regarding the options you've listed, iSCSI doesn't support mounting a volume from multiple places unless you use a shared filesystem. That measns you'd need to either use a shared filesystem, use separate volumes for each client, or use some sort of locking mechanism to prevent multiple mounts. It also doesn't do encryption, so for remote sites you'd have to use a VPN - but I'd suggest doing that anyway as having a unified network has many advantages.

If you do put a VPN in place, then for Windows stuff it might be worth you looking at Microsoft's DPM (Data Protection Manager). I know nothing about it, but the guys at work who deal with the MS stuff have been raving about it like someone's invented sliced bread.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a dead HD and need this CD so I can replace the disk and re-install the printer OS on it. If anyone knows where I might get hold of one I'd be grateful - requests to Canon drew a blank, it's been out of support for years. Alternatively, if anyone has one of these and would let me image their hard disk ...

Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed
author Gladys Hobson. Novels - poetry - short stories - ideal as
Christmas stocking fillers. Some available as e-books.
