rsync can use shells eg ssh. But I don't think you could use ftp as the
"shell" ?

I didn't say it supported FTP.... It is a transfer mechanism on to
itself. But, it does what I think you are asking. It will only
transfer the bits that have changed.
Well thanks, but the data to be transfered is only accessible to me
via ftp....sadly.
There is a later ftp server/client standard that includes modified times
and sizes being available within the protocol. Not every server supports
it, nor every client, but this seems like it would be an efficient way
to achieve it. Some software (w32) I use compares these before
downloading from the master ftp server. I do not know what linux
servers/clients support this enh protocol.
