Kent,
I made something like this for one of my customers before. I used an
RH73 box that I placed in their facility...it used Samba to share server
space with them. Then at night automated scripts used sftp to transfer
"new" or "updated" files to my datacenter.
I had to write some perl scripts to monitor for new files, but they were all
confined to one directory (and its subs), I created a document
(.edoceo.repono.scan) that would keeps track of file names and their last
modified time, then when I was re-scanning the directory any file not in the
list is "new", check timestamps for files that already exist. The script
would then upload the file with a name like "<realfilename>.<date>" so that
I would archive them for a long time. I guess if you are in a secure
environment you could rsync. Find a way to mangle the filenames so that the
backups can accumulate
