Thanks Zack and Jordan. I think some combination of rsync,
srcipts, and C++ code is what I'm going to use. I mainly wanted
to know if there was something like "just install this and it will
solve your problem," which there seems not to be.<br>
<br>
I guess the data size is not so much an issue as the number of
files I'm talking about synching which I think is about 3 or 4
million files. I know that Hostgator limits the number of files
for inexpensive accounts to about 200k, although they claim
unlimited data size (or used to).<br>
<br>
Thanks,<br>

wondering if there's such a thing for Linux file systems.<br>

Also, not all files get closed to the point where they can
be copied every time they're modified. Windows clients are
notorious for keeping files open all day long without
letting other processes copy them.<br>

The thing with the could side is that I don't want to be the
person responsible for running the cloud server, so I'm
going to have to work within the cloud provider's
framework. The ones I'm looking at right now are Google and

Is there a requirement for "every hour" (and not something

that whenever<br>
a file changes, it's sync'd... I'm sure multiple avenues
are possible<br>
with some simple script-fu (and probably plenty of

as well).<br>
