I have a fairly modest Ubuntu box (Jaunty) running as a small webserver. Each night i have a cron job which tar/gzip's important directories and does a simple cp to copy them over to a backup NAS drive which has been SMB mounted locally (effectively an "off-site" backup)
The network connection to the box is 802.11G (54Mbps) so naturally it's quite slow, but the issue is that when the files are being copied, the wireless bandwidth between the webserver and the router is completely saturated by the copy procedure, and web-requests are either denied or incredibly slow to respond.
I've tried using Trickle in standalone mode to throttle the copy procedure, but this didn't appear to make any difference.
Anyone have suggestions or advice? I suspect i need to run some form of QoS on the server but truly have NFI. Was hoping for an easy, silver-bullet solution ;)
