Title: Can Affa backup a non SME Linux server?
Post by: kevinb on December 20, 2007, 05:25:40 AM

Hello everyone,

I have been using Affa for our backups and have been very please with it. It is a very nice contrib.

I have two questions about Affa that someone may be able to answer.

1.)   I have setup an internal SME box to backup the production box and its working great. Now, can I move this box offsite and backup across the internet? Is it secure if I do so?

2.)   I would like to use the Affa box to backup a non-SME Linux server (Centos 5). I gave it a try and it failed when I attempted to send the public key to the Centos box with:

Quote

bash: /root/.ssh/authorized_keys2.8394: No such file or directory
/bin/mv: cannot stat `/root/.ssh/authorized_keys2.8394': No such file or directory
Sending public key to 192.168.1.2 failed.

Does anyone have any thoughts about this?

Thank you in advance for your help.


Kevin

Yes I saw the link but I was not sure how the remote box made contact with the server. Via VPN, SShel, Telnet, Internet or?

Affa was designed for running backups over the internet.
It _is_ secure on the understanding that ssh password logins are _disabled_ on all servers which are reachable from the internet.

ssh only using private/public key authentication

Make sure that "/root" exists on the target box - not all distros create /root by default. You may also need to change the home folder location for the root user on the CentOS box (I figured this out with Ubuntu, but didn't take any notes...)

Thanks

Yes "/root" does exist. "/root/.ssh" does not.

I installed rsync via "yum install rsync".

do I need to do something else?
