Back Up Linux And Windows Systems With BackupPC - Page 2

3 The BackupPC Web Interface

Now that you are logged in to BackupPC's web interface, you should browse the menu to become familiar with it. The entry page is the Status page:

Admin Options allows you to reload the server configuration:

Host Summary shows a summary of all configured clients and their backup status. Currently only localhost is configured as a client for backups. We will remove localhost later on because we don't want to back it up.

Under LOG file you can find the latest log entries:

Old LOGs shows which log files are available. BackupPC has a built-in log rotation mechanism, so there will be more than one log file over time. The max. amount of log files can be specified in /etc/backuppc/

Email summary shows a list of backup reports that have been sent by email. Currently it is empty:

Config file shows the contents of BackupPC's main configuration file, /etc/backuppc/

Hosts file shows the contents of /etc/backuppc/hosts (the file where the backup clients are specified):

Current queues shows requests that currently aren't processed:

Documentation contains the whole BackupPC documentation. You should consider studying it later on:

FAQ and SourceForge are external links to the BackupPC FAQ and BackupPC's SourceForge project site.

In the drop-down menu under Hosts you find all backup clients that are currently configured. localhost is in there by default, but as I said before, we will remove it.

Backup aborted (Unable to read 4 bytes)

This probably means that you have not authenticated to the host with the proper name/IP before.

On the backuppc do these commands...
(Remember to say YES to Continue connecting)

ssh -l root whoami

and with hostname only

ssh -l root server1 whoami

and also with the IP

ssh -l root whoami

How can I do this to sync computers on my network to an external VPS on the internet? I can't get it to work.

I think it is the way to specify the hosts that is the problem...

During installation, when the character-based GUI comes up and and asks you to choose apache (probably the only choice), you have to hit the spacebar to select it.  This isn't obvious and if you just hit return to go on, it'll finish installing as if everything's OK, but the web interface won't work.

make sure to 

touch authorized_keys2 

if the file doesn't exist before doing 

cat ~/.ssh/ >> ~/.ssh/authorized_keys2

This problem tends to crop up ever so often and users tearing their hair out while troubleshooting it.

When executing this command on the backuppc server:

ssh -l root whoami

Also execute the command with the hostname of the client:

ssh -l root falko-desktop whoami

If the hostname resolves then you will receive a prompt to confirm a rsa key.
