Hello Nadia,

A cursory glance of the /etc/BackupPC/pc directory reveals that the permissions for per-server config files are 640.  this means that only processes running under the backuppc umbrella of users can access those passwords. 

In essence, if you trust the BackupPC web frontend, and if you trust UNIX permissions, then the only people who can access the passwords stored in the per-pc .pl files are the users who own the computers, and the root user on the server hosting BackupPC (and if you don't trust your sysadmin, you have other problems).

Adios,

Hi Dan, for security, how to encrypt the backup on the server, i use the rsyncd to backup,because its verry simple to install, and it used only in the network, but i found the rsyncdsharpasswd in the config fil, Rsyncd cant encrypt the data, but only authentification with MD4 128 bit (only chanlenge-response). Now im installing Nagios for monitoring backuppc, i havve find the plugin for backuppc.

What security questions do you anticipate?  You can encrypt the disk that backuppc uses if you like but that would hurt your performance quite a bit.  The standard web interface is simple enough that it does not leave a lot of room for unathorized access.  The only real threat is having an 'admin' level user's password given out OR physical access to the system.  On Tue, Jul 8, 2008 at 4:27 AM, nadia kheffache <nadiakheffache AT yahoo DOT fr> wrote: ok dan, thank you for your reply. I asked this question, because I just finished my stage on installing backuppc, and I am preparing to questions of jury, like quotas, security,..

You might be ok if you just setup SOFT quotas and put the hard limits extremely high.  Then the backuppc server would send an email each time someone backed up data over their quota but once they hit that point they would get a notification every single time until an old full backup expired that had some large files that have been deleted. You would be much better off putting a quota on the remote computer for the user in question.  You can do this in windowsXP+ easily. managing quotas in linux is well beyond the scope of this mailing list and google can help you out but I think that this is not a functional solution on backuppc.  backuppc should just do backups, not tell people how much they can backup.
