Can't you just make a copy of the rdiff-backup directory and run the script on there as a test?

Or if you have to have manual instructions, learn a bit about the scripting language and step through it manually yourself? There obviously isn't any simple rdiff-backup command to run or that script wouldn't exist.

Ron, see my utility here:

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

regards, Ron
