[BackupPC-users] IPv6 support
Hello, I'm using backuppc 3.1.0-9 on a Debian Squeeze server and I have some trouble with ipv6. When I define a record for a backup client it doesn't work, I have this message: Can't find host test via netbios. When I add a A record for this client everything is working. Can you tell me if ipv6 support to backuppc is already ok for the version I'm using or if it's on the roadmap of future versions.

Can you tell me if ipv6 support to backuppc is already ok for the version I'm using or if it's on the roadmap of future versions. BackupPC does no communication on its own. At its most simplest (and in the best spirit of UNIX), it is a daemon that coordinates lots of other utilities together. What that means is that the question is not, Is BackupPC IPv6 ready?, but, Are all of the tools BackupPC uses IPv6 ready? As you can imagine, that's a *much* more complex question! For example, the item that you're asking about (Can't find host via netbios) is handled by Samba. The Samba utility is the one trying to resolve the host, and it's not looking for records. So the place to look would be within the Samba project. Of course, you can substitute nearly *any* program (via the BackupPC config.pl file) for the ones that BackupPC is using, so you might be able to substitute an IPv6-ready nslookup (or dig or whatever) command in its place.

[BackupPC-users] Backups tooo slow over WAN - how to split them
I'm trying to backup windows servers with approx 3 partitions of 100G each over a WAN link. This takes 'days' to run and never successfully completes. I'm using rsyncd on the windows machines - and the backup is to a ubuntu server. So, how do you split the backups from a single machine - do you have to create multiple host entries for each machine ? Does this make restore too painful ? Is there anything else I should be doing ?

Re: [BackupPC-users] IPv6 support
Actually, that's not quite the whole picture. BackupPC does do dns name lookup and those calls are not IPv6 compatible. Once such instance is in bin/BackupPC_dump line 503. The gethostbyname() function (at least last time I tried to do IPv6 with BackupPC) does not support IPv6. This causes BackupPC to try to do an nmblookup. If your client doesn't have and IPv4 address and does not respond to nmblookup, BackupPC will fail. However, if you do not use nmblookup, you can just get rid of lines 496-508,510 and BackupPC will work just fine. --Tod -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
[BackupPC-users] Weekly full with no incremental configuration leads to daily full backups
Hi,
I try to configure a client to make only weekly full backups but no
incrementals:
$Conf{FullAgeMax} = '732';
$Conf{FullKeepCnt} = [
'4',
'0',
'13'
];
$Conf{FullKeepCntMin} = '15';
$Conf{IncrAgeMax} = '0';
$Conf{IncrKeepCnt} = '0';
$Conf{IncrLevels} = [
'0'
];
But the above configuration leads to daily full backups.
Anyone have a configuration like mine?
Thanks in advance
Matthias

I think you need to do something like:
$Conf{FullPeriod} = 6.97;
And set $Conf{IncrPeriod} slightly higher. I believe the runs are
scheduled at IncrPeriod intervals and a full is done if FullPeriod has
elapsed since the last run.

I'm using rsyncd on the windows machines - and the backup is to a ubuntu server. This takes 'days' to run and never successfully complete - normally I have to stop the backuppc (via /etc/init.d/backuppc stop) and this loses the already downloaded data If you are running rsync/rsyncd you should get a partial backup when a full fails and the next run should use that as the rsync base. Do you have the latest version installed? So, how do you split the backups from a single machine - so each can run within a reasonable (say 4 hour) timeframe ? Do you have to create multiple host entries for each machine ? Does this make restore too painful ? Is the whole issue about number of files / rsyncd performance You can make a host entry for each partition (or each rsyncd module, which wouldn't have to be partition boundaries), with ClientAlias settings pointing to the same actual host. This will let each be scheduled separately. Is there anything else I should be doing ? MTU size ? MTU size might come into play if you are using a VPN that doesn't handle it gracefully. If you use openvpn, enabling lzo compression might help. Some people work out some other way to get the initial backup (move the server to the target LAN or vice versa, copy to an external disk and mount in a local machine with a ClientAlias point there for the first run, etc.). After your first full completes the rest should be much faster. -- Les Mikesell lesmikes...@gmail.com -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

It uses a perl script to recurse through the pc directory, calculate (and cache if you have enough memory) the file name md5sums and then uses that to create a tar-formatted file of the hard links that need to be created.

This script creates a new temporary inode-number indexed pool to allow direct lookup of links and avoid having to calculate and check file name md5sums. The pool is then rsynced (without hard links -- i.e. no -H flag) and then the restore script is run to recreate the hard links. I recently used this to successfully copy over a pool of almost 1 million files and a pc tree of about 10 million files. See the recent archives to retrieve a copy. Hi Jeffrey, I can't find your BackupPC_copyPcPool. I looking for it on the wiki as well as in backuppc.general. What/where are this recent archive ?

Assuming you have even low-end machines and a 100Mbps Internet, you should be able to get O(5-10MBps) speeds which should complete your backups in well under a day. Perhaps you have some large files that are causing rsyncd timeouts? (you might want to check the 'timout' parameter setting in rsync). Also, look at the client and server logs to see why the backups don't complete. -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
Re: [BackupPC-users] Backups tooo slow over WAN - how to split them
You could just keep the one machine entry, but use the exclude options to only back up a small portion of the machine. Once that completes gradually remove directories from the excluded list until the full backup completes fine. This assumes that most of your data is static and that any files that change can be easily backed up in a daily window.
