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!

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.

Ok, for the record my example config is for BPC 4. Good you could fix 
your setup.

Re: [BackupPC-users] backup localhost: Permission denied

2022-02-06 Thread corona_24 

Thanks Falko!
I tried your suggestion:

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

but now the backup aborted:

full backup started for directory /etc/ (baseline backup #685)
Running: /usr/bin/sudo\ /usr/bin/rsync --server --sender --numeric-ids --perms 
--owner --group -D --links --hard-links --times --block-size=2048 --recursive 
--ignore-times . /etc/
Xfer PIDs are now 72477
Got remote protocol 1667594309
Fatal error (bad version): Exec failed for /usr/bin/sudo /usr/bin/rsync 
--server --sender --numeric-ids --perms --owner --group -D --links --hard-links 
--times --block-size=2048 --recursive --ignore-times . /etc/

Read EOF: Connection reset by peer
Tried again: got 0 bytes
fileListReceive() failed
Done: 0 files, 0 bytes
Got fatal error during xfer (fileListReceive failed)
Backup aborted (fileListReceive failed)
Not saving this as a partial backup since it has fewer files than the prior one 
(got 0 and 0 files versus 0)

So I checked:

su backuppc /usr/bin/sudo /usr/bin/rsync

and it is asking me for a password.

There a two points unclear to me:
1. shouldn't it be avoided by:

backuppc ALL=NOPASSWD :/usr/bin/rsync

2. I don't remember setting any password for user backuppc, at all.
Only for the web interface, which is different.

Or is something totally different wrong?
