This parameter lets you execute external commands - that is, executable programs or scripts - directly after database files were backed up by BRBACKUP.
post_back_cmd = "<post_back_cmd> $"
If the placeholder “$” is set, it is replaced by the following value when called by the relevant command or program:
<exit_code>: the BRBACKUP exit code
BRBACKUP only accepts that the external commands have been successfully executed when:
Exit code 0 is returned
No messages are returned or only messages starting with #INFO
You can use this parameter and pre_back_cmd to do certain pre- and post-processing before and after BRBACKUP processing.
