Hi friends ..
Thanks in advance to all of you guys...
I am new to BackupPC .. and i have done a lot of try and error for
successfully haveing my data back ..
BUT I AM NOTABLE TO RESTORE MY DATA THROUGH WEB INTERFACE
When i select files and click on restore then it says that
"Reply from server was: ok: requested restore of localhost"
but my files are not restored .. and i got the following error in my log
file...
2008-07-11 14:25:41 restore started below directory /backbpo
2008-07-11 14:25:46 restore failed (BackupPC_tarCreate failed)
....
"Reply from server was: ok: requested restore of localhost"
so any idea why its happening ?
i would like to provide u people some out puts and some of my configuration
..
here we go....

I have the same issue when restoring large amounts of data, so I just use
the command line interface. I typically backup to DVD so I pull a tar.gz
off and split it out into 100MB chunks, and then par2 it at 25% and drop
those on DVD.

first of all, thank you for providing detailed information on your setup.
Unfortunately, the problem seems to be somewhat obscure, so I agree with
Craig that we need some more information from your log files. I don't agree
with Dan, backuppc-users' most notorious top-poster, that he didn't manage
to set up restores, so you shouldn't bother either ...
We can try to clear up some misconceptions though.

That would allow backups and restores through sudo/tar, if BackupPC was
configured to do so (which it is not).

That is mostly fine - except that for 'localhost' the command would be
ssh -l root localhost
which may ask you to accept the public key of 'localhost' even if the key
has already been accepted for 192.168.0.96. Presuming that also works without
prompt, it would allow backups and restores via ssh, if BackupPC was
configured to do so (which it is also not).
Additionally, I would like to point out that using both 'sudo' and
'ssh -l root' for the same backup is pointless. One or the other will do,
combining both makes no sense. It makes sense however to ssh to a *remote*
host (which you want to backup) as a *non privileged user* and then
use 'sudo' to gain root privileges for a 'tar' or 'rsync' command, because
in this way, you can limit root privileges to the command invocations needed
(you can even allow backups ('tar -c') but disallow restores ('tar -x')). For
a local backup, 'sudo' is preferable over 'ssh', because it saves you the
unnecessary overhead of encryption and the TCP/IP stack (well, and because
you can limit it to 'tar'/'rsync').

This means you are using *neither sudo nor ssh* for backups. You're simply
running 'tar' locally. This will limit your backups to files readable by
the 'backuppc' user. That's ok for a test scenario, but it won't get you
far later on. Since you've setup 'sudo', you could change that to
$Conf{TarClientCmd} = '/usr/bin/env LC_ALL=C sudo $tarPath -c -v -f -'
. ' -C $shareName --totals';
> # remove extra shell escapes ($fileList+ etc.) that are

The default value of TarClientRestoreCmd (which you don't seem to be
overriding) seems to be
$Conf{TarClientRestoreCmd} = '$sshPath -q -x -l root $host env LC_ALL=C'
. ' $tarPath ...'; # and so on
i.e. tar over ssh. You'd probably want to change that to
$Conf{TarClientRestoreCmd} = /usr/bin/env LC_ALL=C sudo $tarPath -x -p'
. ' --numeric-owner --same-owner -v -f -'
. ' -C $shareName';
(Disclaimer: I'm not sure if LC_ALL=C will survive 'sudo' or be filtered out
of the environment; take it as a gesture of good will.)

You don't need that one for XferMethod = tar.

There's not much in those files ... note that there seems to be no file named
'2'.

There's probably also a backup number 2 ...

You shouldn't do that, and it's definitely not necessary for the backuppc user
to access the files. When you're doing real backups, you definitely don't want
everyone to have full read - let alone write - access on all files in the
backup.
As a side note, if you *only* change the f%2fbackbpo directory and not the
parent directories, your change will have no effect in any case, because
access to a file requires access to the path elements above it.
/var/lib/backuppc and all directories below it should not have any access
for 'others' (i.e. 0xx0 permissions, aka. 'o=').

What if you change the 2s to 3s?
As far as I remember, zero length files are a special case. They should be
restored correctly, but I don't know if BackupPC_zcat handles them. Try
putting some content into your files, doing a backup and then retry
BackupPC_zcat.

We need to know more about why BackupPC_tarCreate failed. I wouldn't
normally expect it to fail, even if the restore process lacks the privileges
to restore the files in question.
