Re: [BackupPC-users] Need Help Configuring a backuppc
2010-02-02 23:51:23
I made a few changes to the Linux machine being backed up - I stopped some unused processes - apache, mysql, and a couple of others, which freed up a fair amount of memory. Then started a new full backup. The backup went a little farther, but now I get a bunch of these errors all in the same directory -
Remote[2]: file has vanished: "/home/katie/.mozilla/firefox/t7hd74mu.default/Cache/CF4DEE1Ed01" Remote[2]: file has vanished: "/home/katie/.mozilla/firefox/t7hd74mu.default/Cache/D
so rsync has died again. I googled the error, and the only recommendation I could find was not to use rsync through ssh, but just use rsyncd without ssh. That should work in my environment since I am just backing up over a :LAN, but is this the real solution? Or, should I just remove
/home/katie/.mozilla/firefox/t7hd74mu.default/Cache/
from the backup? Is that a common practice, to remove browser cache files from the backup?. BTW, no one was using the machine while the backup was taking place, so I am not sure why they disappeared. Mark

My setup is very similar to yours where I have an old 2.6.8 kernel
running on a mini-itx machine 800mhz with gig of memory in it. I did
have similar problems trying to backup my snow leopard osx mac via
rsync. It would just stop with various client has aborted the
process. What I did in the end was try to do directories where it had
stopped ONLY (ie include files only setting in config) and try to
illimunate any problem files. Also although backuppc uses 2.8
protocol I had read on various rsync forums that the later versions
were more efficient in the way they do things with the tree structures
so I upgraded all my rsync machines to 3.7 and touch wood that seemed
to sort the problem. I have just finished doing a full backup of my
laptop after 10 hours and 46gb later, worked a treat.
One thing I found with the laptop also was that it would go to sleep
when on batteries and that would drop the wifi and hence the rsync
would stop.
Hope that helps.

This means that rsync or ssh crashed on the client side. Likely reasons
are being out of memory or file system errors.
Les,
top shows:
top - 10:23:03 up 1 day, 2:50, 2 users, load average: 0.44, 0.58, 0.54
Tasks: 149 total, 3 running, 146 sleeping, 0 stopped, 0 zombie
Cpu(s): 10.0%us, 3.3%sy, 0.0%ni, 77.7%id, 6.7%wa, 1.0%hi, 1.3%si,

Swap: 2000052k total, 20724k used, 1979328k free, 540424k cached
So I should have enough memory, or at least swap space? I will check the
file system. Thanks!
Rsync has a certain amount of memory overhead per file in the tree - at
least for version < 3.x and I'm not sure if the newer versions are
better when talking to backuppc which will downgrade the xfer protocol
anyway. One other possibility is that if you are connected through NAT
or a firewall there can be long periods of inactivity when rsync looks
for mismatching files that can make the connection time out and be dropped.
