Backup Central

Hi there,
I'm relatively new to Debian server management and am having some problems setting up rsnapshot to ssh into my remote server without a password.

I have set up the ssh passwordless access without any trouble at all. I have:
- created a user on the remote server called 'bkp' and given it a root directory and password.
- generated a public key on my local server ($ ssh-keygen -t rsa) and copied to the authorized_keys file on the remote server ($ ssh-copy-id -i ~/.ssh/id_rsa.pub username@remote_host)
I can now log in with SSH without a password.

I then set up rsnapshot which is configured correctly and preforms the desired tasks when I run it manually ($ rnapshot hourly) however it will always ask for the remote users password.

Below is the output:


uvdev@leo:/backup$ sudo rsnapshot hourly
Setting locale to POSIX "C"
echo 2098 > /var/run/rsnapshot.pid
mv /backup/tmp/hourly.3/ /backup/tmp/hourly.4/
mv /backup/tmp/hourly.2/ /backup/tmp/hourly.3/
mv /backup/tmp/hourly.1/ /backup/tmp/hourly.2/
/bin/cp -al /backup/tmp/hourly.0 /backup/tmp/hourly.1

touch /backup/tmp/hourly.0/
rm -f /var/run/rsnapshot.pid
/usr/bin/logger -i -p user.info -t rsnapshot /usr/bin/rsnapshot hourly: \

I have also tried running the rsync command (from the output above) directly therefore excluding rsnapshot and I am NOT asked for a password in this instance. Therefore the problem seems to be limited to only rsnapshot.

If anyone has any advice it would be gratefully received.

Many thanks,
Gareth

as which user are you testing this on your local server, and as what users are you running rsnapshot auomatically

I suspect the former to be some specific users, and the latter to be root.

Hi there,

Apologies for the slow response. I was never notified that I had a reply.

I am running rsnapshot whilst logged in as the user 'uvdev' which is the same user that can ssh into the remote machine without a passphrase. Therefore I think I'm running everything under the one user.

I haven't got to the point where I can set up cron jobs yet because run "$ rnapshot hourly" is not being successful. I presume that this command doesn't instantiate a cron job?

Thanks again,
Gareth
