Some backups doesnt work again

I have troubles with some machines and their backups. A few days ago
BackupPC_dump stop working well for these machines. Meanwhile other
hosts are working fine. The web interface returns an estrange "Tar
exited with error 512 () status".

With a BackupPC_dump -v -i machine I get this even more estranger output:

tarExtract writes the content of /net/web/web3/index.html to the
standard output. There are other files with the same behaviour but they
seem to be ok in the filesystem. Any idea how to resume the backups?

With a BackupPC_dump -v -i machine I get this even more estranger output:

Sorry, BackupPC 2.0.2 has a minor bug with the manual -v option.
It incorrectly outputs some debug messages to stdout, which mixes
in with the tar data which confuses BackupPC_tarExtract. So
ignore the results from BackupPC_dump -v.

You should look at the XferLOG.bad.z file. What errors do you see?

Hi again! I have no luck resuming backups.

I tried to define a new host without no luck. Some machines work but
others don't. I can't understand. Thanks for the help.

The tar xfer method looks for the string "Total bytes written:".
See lib/BackupPC/Xfer/Tar.pm:

if ( /^Total bytes written: / ) {
$t->{xferOK} = 1;
} elsif ( /^\./ ) {
...
}

Your tar says "Bytes escritos en total:". Change that line to:

if ( /^Total bytes written: / || /^Bytes escritos en total: / ) {

or alternatively run an english version of tar.

This was the solution. Seems that Tar.pm doesn't work well with a non
english locale definition. What i can't understand is why some machines
still backup in the same machine. After all it works again. Thanks for
the help and for the software.
