Re: [BackupPC-users] Running Top
That assumption is generally true especially for larger files. for small files, the whole array is dependant on the slowest drive in the array so the access time is slowest drive - controller overhead - parity penalty whcih means that in all circumstances, a file that is less than the stripe size will be written significantly slower than any one drive in the array could do. when files are as large as the stripe size or larger, performance generally improves.

I'm not interested in the size of the backup for each host, but in the percentage of the cpool used by each host. You can't really determine what you want to know. That is, both host A and B will have links to a single pooled copy for any file they have in common so it doesn't exactly belong to one or the other. Also, it isn't very practical to locate the 'other' links to a file so it would not even be easy to determine which files have links only from multiple runs on the same host and which are linked across hosts. -- Les Mikesell [EMAIL PROTECTED] - This SF.net email is sponsored by: Microsoft Defy all challenges.

[BackupPC-users] BackupPC 3.1.0 failing
I've been running 3.1.0 since it was created and I finished setting things up a while ago and it ran for months rock solid, but then one day some machines stopped working. One Gentoo vserver is running 4 of the machines. Gentoo host OS, Ubuntu, Debian and a Gentoo. BackupPC manages to backup the Ubuntu, but not the host OS or the two other vservers. It also fails on a remote internet server running Gentoo, but not the other server that runs Ubuntu. The Debian vserver log file looks like this and that seems to be the same error for all of the failing machines: full backup started for directory /; updating partial #117 Running: /usr/bin/ssh -q -x -l root liferaft vserver debian exec /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --checksum-seed=32761 --ignore-times . / Xfer PIDs are now 23937 Got remote protocol 30 Negotiated protocol version 28 Checksum caching enabled (checksumSeed = 32761) Sent exclude: /dev Sent exclude: /exports Sent exclude: /home Sent exclude: /media Sent exclude: /mnt Sent exclude: /proc Sent exclude: /pub Sent exclude: /srv Sent exclude: /sys Sent exclude: /tmp Sent exclude: /usr/portage Sent exclude: /var/lock Sent exclude: /var/run Sent exclude: /var/tmp Xfer PIDs are now 23937,23949 create d 755 0/04096 . create d 755 0/04096 bin pool 755 0/0 688492 bin/bash pool 755 0/0 25216 bin/bunzip2 pool 755 0/0 25216 bin/bzcat - bin/bunzip2 pool l 777 0/0 6 bin/bzcmp - bzdiff pool 755 0/02128 bin/bzdiff pool l 777 0/0 6 bin/bzegrep - bzgrep pool 755 0/04874 bin/bzexe pool l 777 0/0 6 bin/bzfgrep - bzgrep pool 755 0/03642 bin/bzgrep pool 755 0/0 25216 bin/bzip2 - bin/bunzip2 pool 755 0/08064 bin/bzip2recover pool l 777 0/0 6 bin/bzless - bzmore pool 755 0/01297 bin/bzmore pool 755 0/0 26860 bin/cat pool 755 0/0 45344 bin/chgrp pool 755 0/0 42744 bin/chmod pool 755 0/0 47356 bin/chown pool 755 0/0 69284 bin/cp pool 755 0/0 55052 bin/date pool 755 0/0 47852 bin/dd pool 755 0/0 45016 bin/df pool 755 0/0 92312 bin/dir pool 755 0/04428 bin/dmesg pool 755 0/08592 bin/dnsdomainname pool 755 0/0 24228 bin/echo pool 755 0/0 92436 bin/egrep pool 755 0/0 22120 bin/false pool 755 0/0 52880 bin/fgrep pool 755 0/0 100468 bin/grep same 755 0/0 61 bin/gunzip same 755 0/05864 bin/gzexe pool 755 0/0 53420 bin/gzip pool 755 0/08592 bin/hostname pool 755 0/0 12348 bin/kill Read EOF: Tried again: got 0 bytes finish: removing in-process file bin/ln Child is aborting Parent read EOF from child: fatal error!

[BackupPC-users] Signal=PIPE on restore, and other errors
Searching through the mail archives, I see lots of posts about getting aborts with signal=PIPE on backups. I've got this problem on restore. I have been backing up 5 machines (linux and windows) using rsyncd flawlessly for a few months now. Thought it was about time to check restoring (backups are useless unless they restore!). I had no luck. I had two types of errors. The first thing I tried was restoring from the backuppc server (running debian testing/lenny) to a ubuntu 7.10 box. There, I got a failure with the signal=PIPE error. Responses to questions people have about this error during backup say that some big files can cause it. So I retried restoring a single small file and got the same result. I figured I would try restoring a single small file to other hosts on the network. I tried another debian box and a winxp box (both of which have been happily backed up for months). Both of those fail with unable to read 4 bytes. According to Les Mikesell in a response (to someone having this problem on a backup), it means: Usually this means that ssh did not authenticate correctly to start the connection. Be sure you have tested the passwordless access running as the backuppc user on the server (the key setup is per-user). Not sure where to go with that. I have rsyncd daemons running on all the hosts being backed up. According to step 5 of the docs, the rsyncd approach doesn't use ssh. Do I need to set up a passwordless ssh setup? I thought I have read through the docs pretty thoroughly but I haven't seen how to do this. I'll check again, but if someone can point me in the right direction, that would be helpful. Is the lack of a passwordless ssh also the cause of the signal=PIPE I see going to the ubuntu machine? Thanks. J.S. - This SF.net email is sponsored by: Microsoft Defy all challenges.

If your xfer method is rsyncd, you authenticate with a username and passsword that must match what is in the secrets file on the client. And for a restore, this must give you write access to the target. You can test this by running the command line rsync, using double :'s to separate the host and path, like: rsync [EMAIL PROTECTED]::share/path . or reverse to write.
