Memory && HDD can be added if needed. The biggest problem is that on the server side, the rsyncd processes take between 100MB and 200MB of ram *each*. You will have trouble supporting more than one simultanious client mirror using rsync with 256MB of ram. Memory is a much bigger issue than hard disk speed. For the archive itself, it currently looks like this: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/twed3s1e 159571424 126758571 20047140 86% /ftpmaster In order to bring up a local regional ftp-master mirror, you really should be in contact with the other ftp*.ua.freebsd.org mirrors and be sure that they are prepared to get their feed from you. Also, you should get the initial mirror contents from one of the local servers if possible so that you do not have to haul *all* of the 130GB of data from ftp-master from scratch.
