Download Files from one server to another
I'm trying to find a easy way to move from my old server to my new server. I have about 30 gigs on my old server and I've purchased my new server. What I'm trying to keep from doing is downloading all that data to my home computer then uploading it super slow to my new server. Is there a way from SSH on my new server to pull the files from the old server?
ASKER
No I want to take everything from one to the other, but my home upload speed is only 100k/sec so that would take forever. I figured their should be a way to use my servers with one another to do the transfer. They both have SSH. I'm not sure what SSHD is or rsync? I thought I could just run some get command.
So you have ssh on the new server?
logon to the old server as root
The issue command
rsync -av /path user@newServerIP:/path
logon to the old server as root
The issue command
rsync -av /path user@newServerIP:/path
Yes, you can connect them with a network cable. Get to the old server and try doing
ssh root@IP_ADDRESS_OF_NEW_SER
ssh root@IP_ADDRESS_OF_NEW_SER
Can you do it? If you want to copy everything, you can do
rsync -av / root@newServerIP:/
But you may run into problems considering that you may overwrite some basic files/user accounts etc. It would be better to skip some partitions or folders.
rsync -av / root@newServerIP:/

Ah, ok I see what you mean. No the servers are at 2 different data centers so no luck connecting with network cables. I will have to do the other commands. I only want to copy the home folder now that you mention it. All my websites and data are within it. How can I use rsync to do this, should I do command from old or new server? Is rsync even installed on them? They are running CENTOS 5.5

Do you know the IP addresses of both machines OR the domain names? This info goes after @ sign in rsync or ssh syntax.
ASKER
Yes I will have the IP of both. 1 is up right now (old server). The new one is still being setup so when I do get it I will try this out and get back to you.

One disadvantage to creating a tarball and then copying it over is that you will need space to save the tar file. Depending on how much compression you get, to save 30Gb could take and additional 15Gb or more. Also, if you have connection problems transferring the tarball, you have to start over again.
Rsync is incremental and doesn't require extra disk space. If the connection is broken, you can re-run rsync and it will copy the remaining files, skipping over the ones which are already copied.
On the other hand, rsync can be confusing. The -n (dry run) option will not really tell you what it will copy. And the nonsense about what a slash at the end of the path means always leaves me wondering if I have the command right. If you have enough space on both servers and a reliable connection, use tar.

What partitions do you want to do, I can give you the exact command
Which server has ssh daemon running on it
Use rsync -av.
Do you want to skip any folders, etc?
