rsync

[B0Ti <9915104t@example.com>]

Hello,

I got a debian woody-i386 installer on my harddisk, but some of its
files are missing or corrupted.
What is the best way to upgrade to the latest woody and correct the
missing/corrupt packages?
I was thinking to use rsync, but since never used a mirroring tool
before don't know if it's the best and most efficient way. I have only a
128k line, so I just can't download half of woody again.

thanks in advance
B0Ti.
