Re: [Xen-users] NFS vs SMb vs iSCSI for remote backup mounts

[Simon Hobson <linux@xxxxxxxxxxxxxxxx>]

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 ...
