Hello Bruno,

Running script (Runswhen = before) on a client does work as expected, and the moving of data (the Backup) will not start 
until that script exits, and then, the after script will only run once the data is finished being backed up.

Take a look:


I added the following RunScript resource to one of my simple backup jobs:
----8<----
Runscript {
   RunsWhen = before
   RunsOnClient = yes    # This is the default, but I prefer to be explicit
   FailJobOnError = yes  # Same as above
   Command = "/opt/comm-bacula/include/scripts/sleep.sh 90"
}
----8<----

Here is the simple `/opt/comm-bacula/include/scripts/sleep.sh` script that sleeps for 30 seconds by default, unless some 
other number is passed on the command line (we will pass 90 on in the RunScript above):
----8<----
#!/bin/bash

# waa - 20250319 - Just a simple sleep script for generic testing
# ---------------------------------------------------------------
secs="${1:-30}"
echo "Sleeping ${secs} seconds..."
sleep ${secs}
----8<----



Notice that the script starts at 17:18:23, then, only after 90 seconds, at 17:19:53 does the backup job continue on its way:
----8<----
time: 2025-03-19 17:18:23
logtext: bacula-fd JobId 75599: shell command: run ClientBeforeJob "/opt/comm-bacula/include/scripts/sleep.sh 90"

time: 2025-03-19 17:18:23
logtext: bacula-fd JobId 75599: ClientBeforeJob: Sleeping 90 seconds...

time: 2025-03-19 17:19:53
logtext: bacula-dir JobId 75599: Sending Accurate information to the FD.

logtext: bacula-sd JobId 75599: 3307 Issuing autochanger "unload Volume c0_0007_0004, Slot 4, Drive 6" command.
----8<----


Your pasted configs seem OK at first glance. What I would do is temporarily add some echo commands in both of them to see 
when/if they are even running. Make sure you did not make the same mistake I just made too... Is it possible that you didn't 
reload the Director configs? In that case neither script woulkd even run if the Director did not know about them. :)

A bconsole command:
----8<----
* show job=xxxx
----8<----

Will show you if the Director knows about the new RunScripts in this job:
----8<----
[...snip...]
--> RunScript
   --> Command=/opt/comm-bacula/include/scripts/sleep.sh 90
   --> Target=%c
   --> RunOnSuccess=1
   --> RunOnFailure=0
   --> FailJobOnError=1
   --> RunWhen=2
[...snip...]
----8<----


The silly mistake I made was that I wrote the script on one system, then added the RunScript to a job that runs on a 
different system (ie: a system that did not have the sleep.sh script lol)

The problem when I did that was instantly obvious though (ie: No such file or directory):
----8<----
19-Mar 17:16 x1carbon-fd JobId 75598: shell command: run ClientBeforeJob "/opt/comm-bacula/include/scripts/sleep.sh 90"
19-Mar 17:16 x1carbon-fd JobId 75598: Error: Runscript: ClientBeforeJob returned non-zero status=208. ERR=No such file or 
directory
19-Mar 17:16 bacula-dir JobId 75598: Fatal error: [DE0031] Bad response to RunBeforeNow command: wanted 2000 OK RunBeforeNow
, got 2905 Bad RunBeforeNow command.
----8<----


Hope this helps,
Bill
