[Discuss] rsync question

[John Blomfield]

I have a theory about an issue that I suspect is caused by rsync. As 
part of my backup procedure I sometimes have a large 45GB file to rsync 
from my computer hard drive to a backup USB hard drive. I have noticed 
that this grabs about 80% of the CPU and prevents viewing videos on the 
computer and streaming them over my network. When this happens I have 
abort the rsync process but I still can't view videos. My theory is that 
rsync is caching the partly transferred 45GB file and this is the same 
cache storage space used by the video as a buffer. That is there is not 
enough buffer left for the vidoe. I also notice that when rsync is 
restarted even after a reboot it quickly gets back to where it was when 
it was aborted. Usually the problem clears up after a couple of reboots. 
Is this theory correct or is this all coincidence?
