Centos – 1TB of folder I would like to copy to another server

centosnetworkingstorage

I have a 1TB folder with many files on Centos server
I need to make sure another Centos server has the same folder and files for backup.
right now the backup server has no files. once I copy all the folders I guess I can use "rsync" but for the first copy I think I'll need something else
I have 2 NIC on both servers in cross cable which I would like to use for the backup.
any good idea?
thanks

you can also tar and untar over ssh in a single command, this is good for only one trancefer you can use rsync after you do a full copy

cd /data ; tar cf - . | ssh -C -c blowfish root@server2 "cd /data ; tar xf - "

I am not sure, but it could be faster then rsync when there are a lot of small files

The correct way to do this (though it does change the permissions so you can't just restore from backup if these were important) is to add the following to your rsynccommand

--no-p --no-g --chmod=ugo=rwX

Where

--no-p disables permissions copying

--no-g disables group copying and

--chmod=ugo=rwX ensures that all non-masked bits get enabled

Try rsnapshot (rsnapshot.org). It does exactly what you're after: it's in the RPMForge yum repos (so is packaged for CentOS), operates over rsync via SSH, and keeps a configurable number of incremental backups.

edit: You could implement a recovery front end by exporting the rsnapshot datastore over NFS or Samba (or a webserver/anything else) and let users pick up old copies of their files themselves.
