Need Help - Live Server Cloning
So to the point i need to make a clone of the server expcept for netowkrin config and anythign else that should not diffrer, but i need all file perms, mysql and everything cloned onto the current server. The server im cloning is a centos and the server im restoring will be Xen with a centos Vm(to support future backups).
Now ive read a bit and im not sure i can use DD on a remote server like this, or if i could use rsync to copy eaxctly what i need. The network connection each server has is 1gbps and a 4core hyper threaded processor at a clock of 3.2, im wondering how i can make this transfer as effiecnt as possible and allowing everything to run normally on this server

- I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
Use dd to make a bit-image copy. Use rsync to make file system copies. These are very different, but often complementary, applications. If you are going to do a remote bit-image copy with dd, then pipe it through a compressor such as gzip (with the -c option) to the remote system. That will reduce significantly the amount of network bandwidth required to send the data. Remember that you should use a target drive that is comparable to the source, otherwise data loss may occur.Sometimes, real fast is almost as good as real time.
