FTP mirroring between two servers

FTP mirroring between two servers

[fred pasteck]

Hi,

I'd like to set up two FTP servers, one in each of two
different datacenters.

I'd like for UserA to be able to FTP to ServerA,
upload, download, or delete a file from the server,
and at the same time have UserB be able to FTP to
ServerB and do the same, and have those changes be
reflected on ServerA as well.

The difficulty is that there is no "primary" server,
so using rsync to mirror the two systems isn't
possible -- we don't know whether a file has been
deleted or not yet uploaded to the server.

Ideas?

Thanks,
Fred

I believe PureFTP allows you to run a command(s) once files have been uploaded and whatnot.  You might be able to have it run lftp (an ftp client) which will login to ServerB and perform a mirror.

lftp can do reverse mirrors as well (get files).

eh....

You might look at using a tool like unison. I have been testing it out to
keep some of my servers in sync.
