Dominic, thank you for posting this.  From its description, it would 
seem to do exactly what we need.

I have not tried it.  You'll think this odd, perhaps, but because this 
library is fairly important to us, I am reluctant to run anything that 
I could not first audit; for example, I would want to check for side 
effects, or 'assumptions' about the states of the source path or the 
backup path or the backups there or something, whether there was 
anything which might be problematic over NFS (file locking, for 
example) or whether the size of the increment might matter or, even, 
Debian-version sensitive, but these are just examples of concerns and 
is not meant to be an exhaustive list.  Sadly, I'm not familiar with 
scripting language, so I was unable to check the script to see whether 
our data, or our backup regime would create any problems for, or incur 
any problems following, running the script.

So, I'd prefer to do something 'manually', if it were possible, so 
that I could be aware of what changes were happening.

Again, thanks for posting the script.  I expect it does everything we 
need, and quite safely, but our responsibilities to others mean I have 
to be sure.  Our difficulty is due to our lack of knowledge, and is 
not due to anything in the script.  Were we not quite so dependent on 
the data, and understood scripting, we'd probably be able to check and 
run it.

There doesn't seem to be any advice on this regression topic in the 
archives, we may have to just live with consuming another 100GB of 
filespace.

regards, Ron
