Backup Central

Hi,
The command is not launched w/o error in the log. My config file:

Job {
Name = "BackupDagobah"
JobDefs = "SA1Job"
FileSet = "Wordpress Set"
Client = dagobah-fd
RunScript {
Command = "/usr/bin/mysqldump --user=wordpress --password=XXX
wordpress > /srv/wordpress/db/wordpress.sql"
RunsWhen = Before
}

But the director display something when it parses the config file:

$ sudo /usr/sbin/bacula-dir -f -d -c /etc/bacula/bacula-dir.conf -t
bacula-dir: dird_conf.c:1860-0 runscript cmd="/usr/bin/mysqldump
--user=wordpress --password=XXX wordpress >
/srv/wordpress/db/wordpress.sql" type=|


Any ideas?

I suspect the problem is that running an internal command does not have
shell semantics, or, to put differently, the call does not go through
the shell.

What that means, is when you run
cmd >file
from within a shell (or in a shell script, which is essentially the
same) the shell opens the file "file" and then runs the "cmd" command
with its stdout redirected to the file descriptor assotiated with that
opened file; after the command exits, the shell closes the file.

But bacula just calls something like execv(2) on your arguments,
so your mysqldump binary gets those ">" and "/srv/...." arguments
literally and has no idea what to do with them.

So either use something like

Command = "/bin/sh -c '/usr/bin/mysqldump --user=wordpress --password=XXX wordpress > /srv/wordpress/db/wordpress.sql'"

or create a shell script and specify its name.
