F*EX use case: 1.2 TB down under

A German nuclear physics institute had 1.2 TB data in 12000 files (100 MB each) to transfer to a university in Australia.

The source host was behind a firewall without any connection to the internet, but it could reach their fexserver. Local disk space run short, so they used:

    fexsend -a labdata.tar labfile* wombat@down.under.au
With this command fexsend sends all 12000 files inside a POSIX tar container to the fexserver without using local temporary files!

Of course the fexserver and the recipient needs enough disk space.

Both, sender and recipient were able to interrupt the transfer and resume at the last transfered byte. An instable link was no problem. Indeed fexsend is able to reconnect automatically.
