A bug(?) with pre and postbackup scripts

Just encountered this, so:

When using prefilebackup and postfilebackup scripts I only see prefilebackup script’s output in the log. I can see that postfilebackup script is still being run, as directories that need to be removed are removed but I still would like to see that in my log. Is that a bug or is my code wrong? By the way, could you add “Running postfilebackup/prefilebackup script” to log?
