Have you read http://doc.bareos.org/master/html/bareos-manual-main-reference.html#BpipePlugin especially the part of: "Please note that the two items above describing the ”reader” and ”writer”, these programs are ”executed” by Bareos, which means there is no shell inerpretation of any command line arguments you might use. " You should test to set reader and writer to a single program without parameter and specify the full path of the program, like Plugin = "bpipe:file=/MySQL/mydb.sql:reader=/usr/local/bin/mysqldump.sh:writer=/usr/local/bin/writer.sh" |

So the examples from documentation is not right? http://doc.bareos.org/master/html/bareos-manual-main-reference.html#x1-427000H.2.3 |

The documentation you are pointing to seems to be correct. However, In your example, you use "writer=/bin/sh -c 'cat - > /tmp/mydb.sql'" which might causes problems. The approach I pointed out is safe. Have you tested it? |

For example, no luck with: Plugin = "bpipe:file=/MySQL/mydb.sql:reader=mysqldump -uuser -ppassword --databases mydb:writer=" (writer is empty) or Plugin = "bpipe:file=/MySQL/mydb.sql:reader=mysqldump -uuser -ppassword --databases mydb:writer=mysql -uuser -ppassword mydb" (this one is described in documentation) or Plugin = "bpipe:file=/MySQL/mydb.sql:reader=mysqldump -uuser -ppassword --databases mydb:writer=/usr/local/bin/scriptwithcat.sh" (this one is described in doc) Neither works. |

However, this one works Plugin = "bpipe:file=/MySQL/mydb.sql:reader=/usr/local/bin/mysqldump.sh:writer=/usr/local/bin/writer.sh" (you proposed) |

I'm glad, that at least one configuration works for you. I rechecked the documentation using 2 Linux machines and it works like expected. Maybe some other behaviour from FreeBSD on parameter handling in execvp? I'm closing this for now. During the tests, I found a bug in the documentation (some bpipe examples do miss the "writer=" parameter). I'll fix that one soon and may strengthen the advice to use commands without parameter. |
