Re: [BackupPC-users] initial backup seems to loop again and again
Hi, Matthias Meyer wrote on 2009-04-01 20:58:55 +0200 [[BackupPC-users] initial backup seems to loop again and again]: I've a problem with the initial backup of a vista client, called myclient. This client ist connected over internet with an 1Mbit/s upload bandwidth and have 100GB of storage to backup. that makes something like 9.5 days (in the best case) to complete the backup. Unfortunately the internet connection will be interupted each night for 5 minutes. [...] Whats happening theire? How to continue an interrupted backup? I can't really tell you. An interrupted backup should be continued (provided it is retried within the PartialAgeMax window (3 days by default). As I understand it, the again interrupted result would constitute a new partial, so the 3 day period would restart with every new (successful) partial backup. [...] In the clients logfile I found out that the file file1 will be saved after 16 hours in the first run and after 12h, 8h, 6h again in the following runs. This sounds like a changing file (meaning the contents would *need* to be transferred again each time), and it seems to be getting transferred earlier each time (contrary to your observation that there is no overall progress). Also keep in mind that the last partially transferred file is removed (and not reused). If you've got a huge file somewhere, that might explain the lack of progress. All of that said, successful full backups are much better than relying on partials to eventually complete. I would suggest to either think of a way to do the first backup locally (you could build a copy manually with rsync, though that would obviously mean using up the full available bandwidth for 10 days, or ship a USB disk or 22 DVDs ...), or to start with a long exclude list, limitting the backup scope to an amount of data that can be transferred, and gradually remove excludes (so that each backup will be able to complete successfully). If you choose the second option, do alternating full and incremental backups to get the most out of your time window. One thing you should think about first, though, is whether your bandwidth is sufficient for the expected *changes* in your data. In the *best case*, you've got 10.54 GB/day, though you probably shouldn't rely on being able to use more than 9 GB/day. Exceeding that would also explain why your partials are not making any progress. Do you need the link for anything except backup traffic? Do you trust backups that regularly take many hours to complete? Hope that helps.

Re: [BackupPC-users] debian/freebsd
dan wrote: http://linux.slashdot.org/article.pl?sid=09/04/05/39 just an FYI for those that are fans of debian and of freebsd. Debian is now shipping with a freebsd kernel. This will give a debian userland to the freebsd kernel, and access to debian packages. I cant wait to see this mature as well as the ZFS freensd port. as these two stabilize this will create an excelent platform for backuppc. The FreeBSD kernel is top-notch and can certainly trade blows with the Linux kernel, debian is one of the dominant distributions (I am including durivitives like ubuntu) and ZFS is a filesystem that seems almost custom tailored to backuppc type workloads. Yeah, great!

Re: [BackupPC-users] Nmblookup doesn't find anything, host can't be found
There is an alternative solution. It is not elegant, but it works.
If the server is the GNU/Linux box, add the IP addresses of your network
hosts to /etc/hosts. There is a similar file in Windows XP and probably
Vista.
On the GNU/Linux host open /etc/hosts with your favorite text editor. Add
the following lines and save the file. I don't know what the IP address of
each host is, but I will use 192.168.1.1 for faith-pardus and 192.168.1.101
for Samsung.
192.168.1.1 fatih-pardus
192.168.1.101 samsung
In Windows XP, the hosts file is located at C:\WINDOWS\SYSTEM32\DRIVERS\ETC,
and the format is the same as Linux. The format is identical because the
hosts file system predates GNU/Linux and Windows and was adopted by each.
The drawback of this solution is: If your IP addresses change, you must edit
the hosts file on each (every) machine. Since your network is probably
small, you are unlikely to have a problem. If you do, the fix is simple.

Hi Dave,
I've just configured it to 1, but i've earlier tried every possible
combination, that means i've tried 0,1 and dhcp without any sucees.
In config.pl, I've wrote this:
$Conf{DHCPAddressRanges} = [
{
'first' = '100',
'ipAddrBase' = '192.168.1',
'last' = '150'
}
];
My Gateway is 192.168.1.1. I own a Linksys router, which i have
configured to be in DHCP mode.
This mode begins with 192.168.1.100 and 50 machines can connect.
I suspect your problem is related to backuppc not being able to talk
nmb to your windows machine. I think you need to look at the
firewall/filtering on the windows machine, and also ensure file/print
sharing is enabled. Follow those basics, if you can, make sure you can
see it from another windows machine before getting back to backuppc.
Hope that helps.
Regards,
Adam

Re: [BackupPC-users] Next release

I am running version 3.2.0.
Actually you are running CVS.
can someone tell me why
$Conf{BackupFilesExclude} is not working. It still backups up all Temp
folders, and .mp3 files, etc. The backup method is SMB.
Can you send the first few lines for the XferLOG file?
