I know how bpipe works and my method using script is to work around an issue with bpipe erroring out with "Error closing stream for pseudo file" (no idea why, but running the same mysqldump command from inside script solves this). Contents of the script is really straight-forward and doesn't change behavior of the dump being sent to STDOUT:

|#!/bin/sh|
|user=backup|
|pswd=PASSWORD|
|if||[||"$1"||=||"-R"||];||then|
|||/usr/bin/mysql||--default-character-||set||=utf8 -u||"$user"||-p||"$pswd"|
|else|
|||/usr/bin/mysqldump||--single-transaction --routines --events --opt --max_allowed_packet 128M --default-character-||set||=utf8 --log-error=||/var/log/mysql/mysqldump_err||.log -u||"$user"||-p||"$pswd"||--databases $*|
|fi|
|exit||0|

BTW, I discovered that the error "bpipe-fd: Error closing for file /srv/mysqldump.sql" was caused of the wrong credentials I had in the script. The first error still remains.

    Hello Silver,

Hello Silver [2],

Please read: http://bacula.us/using-bpipe-to-stream-dumps-vm-clones-and-another-data-to-your-backup <Please%20read:%C2%A0http://bacula.us/using-bpipe-to-stream-dumps-vm-clones-and-another-data-to-your-backup> bpipe reads a command data that is directed to stdout and stores in backup with the name you put in the 2nd variable (fifo path) => I hope is what you are trying to achieve with your scripts. While in restore Bacula uses the last bpipe configuration variable (command) to read from stdin and restore your data with the application of your choice. I never saw a bpipe usage documentation with scripts, but with commands directly. E.g.: Plugin = “bpipe:/mnt/fifo/heitorfaria.sql:mysqldump -u root -ppasswd –databases heitorfaria:mysql -u root -ppasswd″ The beauty of bpipe is you don't need local disk space to generate the dumps since fifos actually don't hold data (it just streams it to an end) and you may also automate application restore directly to it. I recorded some videoclasses that you can find in the same URL post I provided.

            The same error? Have you checked permissions?

                    Aha, I indeed didn't have /mysql directory. Thanks
                    a bunch! :)

                    PS. Script permissions are correct as otherwise
                    the dump wouldn't have been created.

                        Does the /mysql directory exist? It must.
                        Make sure also bacula-fd daemon OS user has
                        proper permissions to run the scripts

                            Hi.

                            I'm backing up MySQL databases from several servers 
with Fileset line:
                                  Plugin =
"bpipe:/mysql/mysqldump.sql:/etc/bacula/scripts/mysqldump.sh <http://mysqldump.sh> mydb:/etc/bacula/scripts/mysqldump.sh <http://mysqldump.sh> -R"

                            FD on some of those servers give the following 
error:
                                  Warning: Cannot stat file 
/mysql/mysqldump.sql: ERR=No such file or
                            directory

                            I've confirmed that actually the MySQL database is 
still backed up and
                            can be restored too. So why the error? Anybody 
knows or can guess?
