I have
"live" mirroring of my disks - all disk writes are mirrored
over the net in real time to [backup images elsewhere].
Just out of curiousity...
Is this done on a file by file basis [i.e.
if the file is changed, the file is copied...], or some other more
granular means? I ask because most of my data operations involve many
relatively
small writes to varying sections of very large files.
If it involves writing to few disk blocks, it would mean little data
copied over the net under my scheme.
