[time-nuts] Odetics 325 & 425: File recovery

[Didier Juges]

Several people pointed me to rsync. I remember now why I do not use it. rsync requires a client tool and a server tool, so you have to have one part running on each machine. My ISPs do not provide telnet access, just ftp, so I have to use a tool that runs on the local Windows machine (I could use a local Linux box if that's the only way) and that accesses the other machine via ftp.

So, unless I am reading this wrong, rsync is out of the question for me.

I can run all sorts of programs on the remote Linux box, as long as I can run them through the cgi interface, so that precludes any kind of console based interactive program. At the moment, I have a Perl script that creates an index of all the files on the remote machine (I use that for the Search function on my Manuals pages), so I am considering writing a tool that compares the local and remote directory structures using that index so that I know which files have to be moved in what direction. I just don't need another software project at the moment...
