The -t option is for sendmail to tell it the To: address is already in
the headers. You need to use a sendmail-compatible program in
$Conf{SendmailPath}. Postfix and other mailers generally supply one if
you don't run sendmail.
Thanks for the reply.
I just checked sendmail on the BPC-server; it's installed and the daemon is
on and it is running. I'm running BPC on CentOS v5.5-i386 if that is of any
consequence.

I use the daemon rsyncd cause the security guy told me that this solution is more secure than using rsync/ssh without password between the machines (backuppc is installed on a real server used for other things, too) I wouldn't agree with that, but the security weaknesses are different. With ssh keys, security depends entirely on protecting the private side of the key pair. Anyone who can be root or the backuppc user on the backuppc server can steal the identity file and get root access to the remote servers - and you should assume that anyone who has physical access to the server could do this, perhaps by booting a live cd to bypass its passwords. However, as long as the private key is protected, ssh sessions are fairly secure and the data over the network is encrypted. Perhaps your security guy misunderstood and thought you needed to remove the root password, which is not necessary when using ssh keys. Running rsyncd instead, you also have the issue of your passwords being stored in plain text on the server and the data being passed over the network without encryption - but you do have some control of which files can be accessed. It is also possible to make the ssh connection as a non-root user, then use sudo to become root with restrictions on the possible commands. I think the details for this are posted on the wiki somewhere, but basically if you permit restores you can pretty much do anything to the target machines anyway.

to /usr/sbin/sendmail which is used on CentOS.

Re: [BackupPC-users] Restore takes way too long and the fails
Hi, I unpacked the tar on the backup server itself, which is also the host on which I used firefox to download the tarfile. The only tar I found is version 1.23 (corresponding to the debian/testing tar package 1.23-2.1) However, my primary problem is not tar. The primary problem is that I have reproducable crashes in Backuppc, when trying to restore some files of the backup, while other files can be restored without problem. I was failing restoration to o Windows Vista + ntfs + smb o Windows Vista + ntfs + rsyncd / Cygwin o Linux (GRML) + ntfs + rsync via ssh + (mounting nfts in rw-mode via ntfs-3g) What does work is: o downloading the problem file via tar o restoring to localhost (Linux (Debian) + rsync via ssh) I was close to blaming NFTS, but since I can untar the file to NTFS via the GRML boot, I'm not sure this is right.

Another question: The script, running with -c, failed eventually
at this line:
my $err = $bpc-ServerConnect($Conf{ServerHost}, $Conf{ServerPort});
My serverport is set to -1; does it need to be set for this to work?
Could you not just call BackupPC_ServerMesg instead? Perhaps I
should hack my copy locally to do that...
