SCP, NFS, Netcat Tar Pipe

[bambock]

Hey Everyone,

I am working on developing a script to copy data from one system to another across our gig backbone, and I thought I'd ask to see if anyone had a preferred method of accomplishing a task like this.

Options I've considered:
[ol]
[li]mount nfs filesystem and copy data over and umount the filesystem.[/li]

[li]use scp with recursion.[/li]

[li]use find, tar, and netcat and coordinate a tcp listener on the remote host.[/li]
[/ol]

Hi bambock,

I like and always use the following command:

cd /Dest_dir

rsh Source_hostname 'cd /Source_dir; find . -print | backup -ivf -' | restore -iqvpf -

You have to off course set up rsh connectivity first (or else you might have to consider ssh for security issues)

I assume since you were trying to use scp then your ssh is alreayd set up so its easier to go directly to ssh instead of rsh!

Now all of this depends as well on whether you focus on speed (shortest time) or security.

Regards,
Khalid

I've always used rsync/rdist for this kind of task.

if this is a one time deal then i suppose any one of your options would work...
