What is "sync"?? My man-page says "sync (1) - flush file system buffers"

The old backup-server is offline since yesterday after another disk died. It was old enough, the new one (the one with open-e) has to do it now.
Open-E sounded good for me because i do not have a whole system to look after with updates, but i see its not what i am able to use.

The main Problem is, that i am a "remote admin" and open-e does only accept connections from local intranet. And iam not part of the lokal intranet, as my webserver is not, too. So i cant connect to anything but the remote-console which is not useful at all. The nice (and terribly slow) web interface is only accessible for me with some dirty hacks (proxy-scripts on my webserver with NAT to internal network for example). Lynx does not support javascript

@asaph07: Thats is exactly the problem i have: my firewall is configured right (i had only to change IP adress from the old backup server to the new one), but the open-e does not accept any connections from other subnets (and the DMZ is another subnet, of course ).
But the connection from local intranet doesnt work with rsync, too.


My solution for now is quiet simple: my Application-Server has to do the work of the old backup-server (rsync-server, incremental-snapshot-rotation), the open-e system just serves a big NFS-Share. But that is no satisfying solution.
