Hi,

I have still v3.3.2 on an ubuntu 20.04 LTS server.

I tried

backuppc  ALL=(ALL:ALL) NOPASSWD: /usr/bin/rsync --server --sender *

but same error.

Your other config settings seem not to be available at v3.3.2, like:

$Conf{RsyncSshArgs}
$Conf{RsyncBackupPCPath}

Anyway, I solved it.

I am using these settings now:

$Conf{RsyncClientCmd} = '$rsyncPath $argList+';
$Conf{RsyncClientPath} = '/usr/bin/rsync';

and for visudo:

backuppc  ALL= NOPASSWD: /usr/bin/rsync

Thanks all for supporting!

Hello,

I try to backup my local host.
I made these settings:

$Conf{RsyncClientCmd} = ' /usr/bin/sudo $rsyncPath $argList+';

and allow backuppc user to run rsync with sudo without password
(visudo):

backuppc ALL=NOPASSWD :/usr/bin/rsync

Anyway, I got the following errors:

incr backup started back to 2022-01-29 01:00:01 (backup #677) for
directory /etc/
Running: /usr/bin/rsync --server --sender --numeric-ids --perms

Remote[1]: rsync: opendir "/etc/multipath" failed: Permission denied

...(list is actually longer)

It seems, everything what can only accessed by root, failed by backup:
drwx------   7 root root  4096 Dez  4  2016 localauthority/

Which settings are missing?

Hello,

I will assume we are talking about BackupPC 4.x . For my localhost I
have this in the host config:

$Conf{RsyncSshArgs} = [
  '-e',
  '/usr/bin/sudo -p'
];

On the server config:

$Conf{RsyncClientPath} = 'sudo /usr/bin/rsync';

$Conf{RsyncBackupPCPath} = '/usr/libexec/backuppc-rsync/rsync_bpc';

In "sudoers", depending on your sudo version you may need to either
specify the exact full command (get it from the error message), or use
a wildcard:

backuppc  ALL=(ALL:ALL) NOPASSWD: /usr/bin/rsync --server --sender *


This is "certified to work" for me at least (on Debian).

Hope it helps.
