Backing up to remote server securely

Hello,

I am trying to find a solution of backing up my server to a remote server. The key is to do this securely without having files placed directly on the server I am trying to back up. Here is what I am trying to do:

As root:

Code:

root@localhost$ tar -cz /path/to/backup | ssh backupusr@remote.host.com 'dd of=/path/to/store/backup.tar.gz'

However, this prompts me for "backupusr's" password, which I don't want since I will be using this in a script. The backupusr has public/private keys so if I am logged in as the backupusr and ssh to remote.host.com, I log right in without a password.

For security purposes, I do not want to mount an NFS share nor use Samba. Any ideas?

Thanks!

look into sbackup (Simple Backup)-- it was created during a google competition last summer.

i don't know if it encrypts pw or not.. but i do know it is simple, flexible and it works.

good luck.

Create a public/private key pair as root@localhost

Code:

ssh-keygen -t dsa

Now open the file /root/.ssh/id_dsa.pub and copy and paste its contents into /home/backupusr/.ssh/authorized_keys on remote.host. Now you should be able to go

Code:

ssh backupusr@remote.host.com

and it will automatically log you in to remote.host.
