Re: [BackupPC-users] NAS performance over NFS

2008-09-01 Thread Stephen Vaughan
Hmm yeah I've a bit of a play with the nfs client side, the nfs server is
purely web based, so it's limited to what I can play with.

What about the network side of things, with data coming in and back out on
the same interface?

You probably need to consider that performance of NFS is never likely to
be as fast compared to local disk (unless your NFS Server has slow disks
and your local disks are fast).

However, to optimise the performance you are getting now, you need to
start by focussing on improving your NFS performance, so ignore
backuppc, and run various tests, follow the available NFS performance
optimising howto's from google, and then throw backuppc back into the
mix.

I don't recall the details, but I was having a number of performance
issues with my NFS server, and after fixing the NFS mount options, and
the NFS export options on the server, along with tuning a number of
variables on the NFS server (under /proc/something) I managed to resolve
most of my problems. (The final problem (which was probably the first
problem) was that the NFS client had faulty RAM)

Hope this helps in some way...

[BackupPC-users] NAS performance over NFS

2008-09-01 Thread Stephen Vaughan
Hi,

We have backuppc running on a server, with an NFS mount to a NAS device.
Everything is gigabit, there is only 1 nic in the backuppc server connected
to the switch, so traffic comes in from the servers we're backing up and
then straight back out the same nic to the NFS mount.

I'm finding significant performance drops in backing up data to the NAS via
the backuppc server. When we run backups to the local storage in the server,
the backups run much faster and the network usage is almost triple. I know
NFS won't be as fast as the local storage, but is it possible the network
card is conngested?

Would it be better to plug in a second nic to the backuppc server and allow
traffic to come in via nic1 and out to the nfs mount via nic2?

thanks
Stephen

[BackupPC-users] Backuppc not working (can't read 4 bytes error)

2008-09-01 Thread David Hopkins
I have installed backuppc and can access the CGI interface via apache.
 Apache runs as the backuppc user.  I added the localhost to the
backup to run a single backup against the backup server before trying
to backup other systems.  However, I get the can't read 4 bytes error
message when I try to run a backup.  I have the user for the host
listed as root.  However, changing it to backuppc doesn't help.  Also,
I have set up and tested the ssh keys for both root and backuppc
accounts so I don't have to enter anything to log in via ssh. I
checked that perl can resolve the localhost and that works.  I also
tried changing the command to use /usr/bin/sudo $rsycncommand
$arglist+  but that also error'ed out.

FInally, ran the command interactively but the results don't seem
correct.  Specifically, the xfer.log error is:

Running: /usr/bin/ssh -q -x -l root ncsfs2 /usr/bin/rsync --server
--sender --numeric-ids --perms --owner --group -D --links --hard-links
--times --block-size=2048 --recursive --checksum-seed=32761
--ignore-times . /home/
Xfer PIDs are now 30725
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Done: 0 files, 0 bytes
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)
Not saving this as a partial backup since it has fewer files than the
prior one (got 0 and 0 files versus 0)

Also, it this seems command would backup . to /home/ ?  At least if
run as root that is the exact behavior.  Just running the rsync
portion of the command takes all files in the current directory and
places them directly in /home without subdirectories.  Finally, the
presence of --server and --sender cause the command to fail as well.
Removing them and the command will run interactively but with them it
will not.

I have deleted and recreated the ssh keys, changed the command line to
use sudo which then gives a different error: It says you need a tty to
run sudo.  At this point I am not sure what to try next.

Sincerely,
Dave Hopkins

in SAMBA 3.2 the authentication got different. you will have to check

i assume the problem sits in there...

backuppc wouldnt have any defaults to not back those up.

it is likely that you have something like iTunes or windows media player
open locking those files.

Hello,

Not sure it's really BackupPC related... I remember that Windows refuses
to copy some files when they're in use ; you maybe could check if it was
the case for these files when you've tried to bakcup them.

Hope that helps,
