[BackupPC-users] Parent read EOF from child only on large files (over 3GB)
Hello List, I have a problem with backuppc, which maybe you could help me to solve. I am using rsyncd to perform the backups, and they work, unless there are very large files (3GB or larger). In this case, they fail. This is what I get on the backup machine: ... create 660 106/109 5242880 home/mysql/ib_logfile0 create 660 106/109 5242880 home/mysql/ib_logfile1 Read EOF: Connection reset by peer Tried again: got 0 bytes finish: removing in-process file home/mysql/ibdata1 delete d 755 106/1094096 home/mysql/test delete 660 106/109 3095396352 home/mysql/ibdata1 delete d 700 106/1094096 home/mysql/postfix delete d 755 106/1094096 home/mysql/mysql ...

Re: [BackupPC-users] Ensuring two hosts are not running simultaneously
Thanks Nils. The post certainly clears things up for me. I will try and implement the same.

My filesystem supports large files. In fact, after retrying several times, the
backup completed!
I know that the network was a bit slow this morning. Maybe I can increase some
timeout parameters somewhere? I have already set the ClientTimeout to
near-infinity ($Conf{ClientTimeout} = 72000;) but it was like this also
during the failures...

[BackupPC-users] External WD Worldbook Device
All, Up until very recently I have had BackupPC 3.0 working with my 1TB external WD Mybook world edition device, which is connected to my LAN and which I mount via cifs. I recently had to upgrade my machine to a newer version on Linux (Mandriva 2009.0) and with that comes BackupPC 3.1. Once I had setup installed BackupPC 3.1, mounted my backup device using cifs and restored my configuration files I started up BackupPC only to get the message: "Can't create a test hardlink..." And BackupPC would not start :-( Thankfully I have been able to comment out this check from the BackupPC program and get BackupPC up and running so that I can restore what I need from my backup drive via the web interface. Under BackupPC 3.0 I never had a problem performing backups and I can still access the backups that I have from the 3.0 version. There are no error messages in any of the log files. So, did something change between 3.0 and 3.1 ? Is there a way I can check manually by creating a hardlink on the backups partition from the shell ? Sorry, not a Linux guru so not well up on the commands to do this. I did take a look through the archives but nothing jumped out to me as to the problem. I would assume that since backups were working just fine with 3.0 that they should be fine in 3.1 and that my external drive is ok? Would appreciate any help as I'd like to get my backups up and running again. I did do a df -i and got the following output: FilesystemInodes IUsed IFree IUse% Mounted on //192.168.15.6/public 116M1.7M115M2% /backups Regards, <>-- ___ 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 probably doesn't have the backup storage configured as /backups, but maybe /var/lib/backuppc. The easiest way is to stick to that location and mount your NAS there. You may check whether hardlinks work correctly by opening a shell and doing: echo hello > testfile ln testfile linkedfile echo olleh > linkedfile cat testfile There should be no error messages and the last command should output "olleh". If you do an ls -l testfile linkedfile, you should see something like this: -rw-r--r-- 2 root root 6 2009-03-26 16:25 linkedfile -rw-r--r-- 2 root root 6 2009-03-26 16:25 testfile - note the 2 here! It says: link count 2.

Re: [BackupPC-users] External WD Worldbook Device
I'm not sure what the filesystem is. I suspect it is NTFS. I guess whatever these drives come as. I did try what Tino suggested and this is what happened: [r...@dtwconsulting backups]# echo hello > testfile [r...@dtwconsulting backups]# ln testfile linkedfile ln: creating hard link `linkedfile' => `testfile': No such file or directory So yes, does look like there is a problem. I have checked my previous backups and don't see any errors though, and I was able to restore some of the files ! Is there a way that I can reformat this drive to ext3 ? Is it even possible to format the drive from linux when it is mounted as cifs ?

How are you creating these new files? If you use a method that preserves and older timestamp (like unpacking a zip file, etc.), they won't be picked up in an incremental if they appear older than the previous full. If you use the rsync or rsyncd methods it will actually compare the contents of the runs to detect changes regardless of the file timestamps. -- Les Mikesell lesmikes...@gmail.com -- ___ 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/

Incremental backups work by transferring only files whose last modification time is younger than x. If you unpack an archive, the last modification time is restored as well, so the incremental backup will not consider the file as new. Only rsync-based transfers are able to detect such changes because they build and compare a file list on the server and client.

Re: [BackupPC-users] External WD Worldbook Device
Les, I believe that under the Mandriva package we are allowed to change the TopDir and it is in the config.pl file. When I originally started Backuppc it was complaining that it could not create a hardlink under /backups/pc/ and /backups/cpool. It wasn't looking at /var/lib/backuppc. Even with version 3.0 I had TopDir set to /backups and backups were being created under /backups. Perhaps it has been 'failing', but I had valid backups that I have restored from. Whether it was wasting space I don't know, perhaps it was. Also, even though I cannot currently do backups I can restore from existing backups and the restore is coming from /backups. Based upon that I would say that the Mandriva package allows the change of the TopDir.

If pooling had ever worked you should have a large tree of files with long hash codes for names under the pool or cpool directory. Does 'ls -lR' or 'find' show them? Backups are stored under the appropriate pc directories in any case, but the pooling that eliminates duplicate copies can only work when the hardlinks succeed. If you do have pooled files (and ls -l should show link counts > 1), then there must be something different about the mount options on the new system. -- Les Mikesell lesmikes...@gmail.com -- ___ 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] UPDATED: Fully automated script for creating shadow copies and launching rsyncd
I was trying to figure out the best way to deploy VSS with BackupPC on my
Windows XP PCs, and found this wonderful script. Thank you so much Jeffrey
for sharing it!
I ran into (and solved) a few issues when deploying version 0.3 of the
script that I wanted to share, in the hope of making it easier for the next
user.
1. The various archives for this mailing list all mangle the script in
different ways, i.e. at signs and colons get changed, extra newlines added,
indents removed, etc. It took me several hours of studying diffs between the
versions on backupcentral.com and mailarchive.com to get a working version.
Could Jeffery post this script in the "User Scripts" section of the wiki?
2. The script requires it be in the group "Administrators". I find it
impossible to set this group on my Windows PCs. When I chgrp a file to
"Administrators" or group number 544, the group name is changed to "root"
which is group number 0. I think this might be because both Administrators
and root both have the same SID in /etc/group. I finally gave up and changed
the script to allow ownership by either "Administrators" or "root" like
this:
#Check permissions on files we call. Also touch SHADOWLOCK
# Set up SHADOWDIR and check their permissions
if [ $USESHADOWS -gt 0 ] && touch $SHADOWLOCK && \
! ( stat -c %A $0 | grep -q "^r.x" && \
[[ $(stat -c %G $0 ) =~ Administrators|root ]] && \
stat -c %A $SHADOWEXECCMD | grep -q "^r.x" && \
[[ $(stat -c %G $SHADOWEXECCMD) =~ Administrators|root ]] && \
If anyone has a better solution to this problem, please let me know.
3. There is a typo in the line:
$DOSDEV "${letter}:" /D 2> /dev/nuul
which should be changed to /dev/null
4. If using nmblookup to resolve PC host names, then the calls to the script
in the pc config files should use $hostIP instead of $host.
5. If you were previously running rsyncd as a Windows service, you need to
remove it, by using cygrunsrv -R.
6. The script needs to be called in $Conf{RestorePreUserCmd} and
$Conf{RestorePostUserCmd} with the additional parameter "-u 0" in order for
restores to work.
Hope that helps...
Dave

I am by no means a Windows expert - but perhaps different versions use
different names for the superuser equivalent. Before I hard code in the
'root' alternative, it would be helpful to know whether these are the
only two possibilities or whether other versions or setups of Windows
use additional terms for the superuser

Can you elaborate here so I know how to change the script?
Would $hostIP work in both cases or is some type of 'test' or config
necessary to determine which one to use?

I do not believe this is necessary. I have the service set up. A
problem would potentially only exist if you had the service started
automatically and left it running (in that case, the script would
either complain about rsyncd already running or kill it depending on
how you have the configuration set up)

To tell you the truth, I never tested the script on a restore.
Actually, I'm not sure you want to use VSS on a restore since wouldn't
you want to restore to the *current* filesystem rather than to a
shadow copy. In fact, I thought shadow copies were read only anyway.
Maybe I'm missing something so please help me here...

Very helpful! Let's continue the dialog and once we get the above
points nailed down, I will release an updated version incorporating
these changes.
