I don't know anything about any of them. I use VMs to be able to run
various versions of software, so I can try things, when something
isn't working. At the moment, I don't have a good setup to try
running a FTP server, so I can't try that without doing another
install.

I never bothered under windows, although the Task Scheduler
should run a program, at a scheduled time. Most operating systems
have some sort of Cron program.

I don't use windows enough to worry about nightly backups. I use
RSync under OS/2 (using the DragText scheduler). There is
DeltaCopy, that runs RSync under windows. I don't know if it would
do what you want.

There are a lot of pieces that fit together, to improve performance.
A fast host definitely helps, but that isn't the only thing.

AFAIK, Hyper-V only works with windows guests.

Web archives are publicly available at: http://lists.2rosenthals.com,
but it seems that a lot of content went missing, when the Arca Noae
servers crashed. I keep them for one year, then delete them. What
you need would be somewhere in the middle of the missing stuff.
I guess I need to do the setup thing all over again, when I find the
time.
