Well, when backup job starts bacula file daemon starts two new threads: a
working thread and a watchdog thread. A working thread is responsible for
all backup procedures. It finds a next file, read, performs an md5 digest,
compression, encryption, backup stream serialization and sends into SD. Step
by step in one thread, at 64kB block size. This is a main bottleneck for
slow backup speed.
