[BackupPC-users] $xferOK in $Conf{DumpPostUserCmd} is equal to 1, even if xfer has failed

[Adrian R. <aru...@gm...>]

I am using backuppc on ubuntu server recently upgraded to 14.04 LTS.
(backuppc version 3.3.0). Since this upgrade, Xfer usually notifies errors
with rsync transfers (md4 missmatch errors). There were no such errors
before.

This backups must execute a dump-post-user-cmd to delete database exports:

$Conf{DumpPostUserCmd} = '$sshPath -q -x -p 20907 -l Administrador $host
/cygdrive/g/backup/bin/delete_exports $xferOK';

---- Log with errors: ----

--------------------------

When transfer fails, $xferOK is equal to 1, not 0. ¿Why?

Thanks!
