The trick is to limit I/O bandwidth for rsync.
The –bwlimit option limit I/O bandwidth. You need to set bandwidth using KBytes per second. For example, limit I/O bandwidth to 10000KB/s (9.7MB/s), enter:
rsync –delete –numeric-ids –relative –delete-excluded –bwlimit=10000 /path/to/source /path/to/dest/?
10 megs a second is plenty of speed and will keep the server running smoothly when your [...]

iptables can block many different things and often it will block good servers inside of a network. The best to see if it’s a iptables issue. Try to clean them out with this if you have CSF on the server:
csf -f
If you still have a issue try to stop iptables like this:
service iptables stop

The best way is:
shutdown -r now
This will tell the server to take it’s time so to speak and reboot when it’s ready.
For a hard reboot simply put:
reboot
In most cases a hard reboot is fine unless you have file errors and the servers needs to clean them up before a reboot.

To get the files out of a tarball, you can use the following commands:
tar xvf something.tar
If the tarball has also been gzipped (compressed), you can use the following command:
tar xvfz something.tar.gz
If you only want certain directories from the tarball, do this:
tar xvzf something.tar.gz */dir.you.want/*
If you have a .tar.bz2 file, then you need bzip2 installed [...]
