I think I may have been misunderstood.. not the first time

Thanks though Mark. The whole point of this operation is to keep the files
in 'what appears to be' the same place.

>F:\dirA\dirAA
>         \dirAB  <- this directory is to be moved to another disk

The directory \dirAB\ logically will not move anywhere, just the data will
have moved to another disk, but all those files will have exactly the same
file-path.
Like you say, if a files PATH has changed then it needs to back it up
again - I appreciate that. Though nothing will have changed.

I should have mentioned before that we will be performing both Image and
normal incrementals on this file system, and although I would not expect
the incremental to have a problem traversing the file system, I'm not sure
about the image backup - is it able to traverse mount points?

I had better RTFM for the last question.

Any answers greatly appreciated.

If you change anything about the name of a file (as in your example,
moving f:\data\file\foobar.txt to g:\data\foobar.txt), you will force a
backup of every file affected, and there will be a new filespace
created, with all of the database pointers involved in that. (After all,
you've changed its location.)

The nice thing is that the old locations of all these affected files
will eventually expire away, because the old file locations don't exist
anymore.
