Topic: [ANNOUNCE] smeserver-backuppc

[Daniel B.]

this is the config file I use for the local host:

Code: [Select]

# Sample configuration file for localhost. release 4

$Conf{TarShareName} = ['/'];

$Conf{BackupFilesExclude} = ['/proc','/sys','/dev','/tmp','/home/e-smith/files','/opt/backuppc'];

$Conf{XferMethod} = 'tar';

$Conf{TarClientCmd} = '/usr/bin/sudo $tarPath -c -v -f - -C $shareName  --totals';

$Conf{TarFullArgs} = '$fileList';

$Conf{TarIncrArgs} = '--newer=$incrDate $fileList';

$Conf{TarClientRestoreCmd} = '/usr/bin/sudo $tarPath -x -p --numeric-owner --same-owner -v -f - -C $shareName';

$Conf{DumpPreUserCmd} = '/usr/local/bin/BackupPC_SME_pre-backup';

and here is what I use to backup another SME server:

Code: [Select]

$Conf{XferMethod} = 'rsync';

$Conf{RsyncShareName} = ['/'];

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

$Conf{RsyncClientCmd} = '$sshPath -q -x -l backuppc $host /usr/bin/sudo $rsyncPath $argList+';

$Conf{RsyncClientRestoreCmd} = '$sshPath -q -x -l backuppc $host /usr/bin/sudo $rsyncPath $argList+';

$Conf{BackupFilesExclude} = ['/proc','/sys','/dev','/tmp','/home/e-smith/files'];

$Conf{DumpPreUserCmd} = '$sshPath -l backuppc sas "/usr/local/bin/BackupPC_SME_pre-backup"';

Maybe you'd like to tweak the include/exclude part. If you're interested, I wrote this morning a how-to for a complete restore (on the same server after a crash or on a different server with different hardware). With this you can test if the restore process goes ok on a test server.

For this to work you'll need to create a user 'backuppc' on the remote server, give him sudo access to rsync and signal-event pre-backup without password and place the script /usr/local/bin/BackupPC_SME_pre-backup with execut permission.
This script is something like:

Code: [Select]


HOME=/root /usr/bin/sudo /sbin/e-smith/signal-event pre-backup

Where do this backups go to?
I am not familar with rsync

[sonoracomm]

Hi Pippin,

To make sense of this, you will need to read up on BackupPC in general...not rsync specifically.

Here is a howto I wrote that may help:
http://www.sonoracomm.com/index.php?option=com_content&task=view&id=86&Itemid=32

Here is the BackupPC info page:
http://backuppc.sourceforge.net/info.html

Here is the BackupPC FAQ, which is very helpful:
http://backuppc.sourceforge.net/faq/index.html

To answer your question, the backed-up data gets stored in a very clever 'pool' on the BackupPC (SME) server.  The main goal is to back up various other machines in an efficient manner to your BackupPC (SME) server and it works quite well.

I get this message and i think i have done it right

Backup failed on 192.168.1.3 (Unable to read 4 bytes)

[sonoracomm]

I suggest you search the BackupPC mailing list archives for help with BackupPC.

This error is fairly generic in that it implies the backup didn't happen, often because of a basic communication failure.

Please look in the troubleshooting section of the howto I already pointed you to.

[pippin]

I think i know the problem,but i dont know how
Its because it ask for the root password on the remote machine and i dont know how to fix it

[sonoracomm]

It's in the howto.

Again, this isn't really a BackupPC issue.

Hi,

I can run a backup only when i use a simple password ???


before with a strengh password :

Connected to ap001:873, remote version 29
Error connecting to module C at ap001:873: auth failed on module C
Got fatal error during xfer (auth failed on module C)
Backup aborted (auth failed on module C)


after a change to a simple password it works, is this a bug ?

Error: Unable to read config.pl or language strings!!

What have i done

You don't have permission to access /backup/cgi-bin/BackupPC_Admin on this server.

Ooops defenetly something wrong here please help

Is there any way to change the default temp space for archives to be built from the default /opt/backuppc/files/archive?

I tried to change it in config.pl to

Code: [Select]

$Conf{ArchiveDest} = '/media/usbdisk/archives';
but that does not seem to do the trick.

My primary disk is running out of room when the archives are built on the same disk as the backups.  I need the archives, but would like them to be built and stored on a separate disk or disks.  Is this possible?

THanks.

Which password are you talking about? the password of the admin to connect to the interface? The password on the host to backup? Please, give more details.

You don't have permission to access /backup/cgi-bin/BackupPC_Admin on this server.

This means there's something wrong with the file /opt/backuppc/files/conf/config.pl
You have done some changes in the configuration (I think through the interface in the server-manager) which are not correct. Try to see what you have changed, or at least, which line and which parameters are concerned.

Is there any way to change the default temp space for archives to be built from the default /opt/backuppc/files/archive?

THere's a way but not with a parameter. You have to edit the file /etc/e-smith/templates-custom/usr/local/bin/BackupPC_SME_archiveHosts

line 24

Code: [Select]

my $tempArchive = "$progpath/files/archive";

Just replace it by the full path you want to use (user backuppc must have write access)

for exemple

Code: [Select]

my $tempArchive = "/tmp";

Then, you must expand the template:

Code: [Select]

expand-template /usr/local/bin/BackupPC_SME_archiveHosts

Hi,

Is there an easy way to temporarily disable making backups with BackupPC without shutting down the program completely? The machines I'm backing up are moving to a different location, I want to stop backups until they're online again.

Thanks,

Oz

To stop the automatic backups of an host, I add this directive in the per-pc configuration file:

$Conf{FullPeriod} = -1;

This way, you can still perform manual backups through the interface but the automatic ones should be ignored

Does anybody have the backuppc directory because i have deleted it by a mistake and i dont know how to uninstall this contrib
