[Bacula-users] df v.s. console job status, size mismatch

[William L. B. <bb...@ad...>]

Hi Folks,
	I just completed my first successful backup across two OnStream ADR tapes. 
That was great.  Afterward, I decided to reconcile what bacula said it wrote
with what RH says is stored on my disk.
	The output of df and the output from the backup do not appear to square up. 
So, I ask for your help.  I have included first the output of df.  It tells me
that 19,574,388 1k blocks are filled with data on /dev/hdc5, my root partition,
and across my other 4 partitions, 8,728,556 additional 1k blocks are used.
	I have marked, via ***** the output of "status ADRDrive" from bacula's console
application.  I have included two "status ADRDrive" commands, one just after I
added the second tape, and one after the backup finished.  Output of "status
ADRDrive" tells me that 18,592,114,545 bytes were written to tape via the
backup.
	18,592,114,545 / 1024 = 18,156,361 1k blocks written to tape.

	So, what happened to the other 
		19,574388 + 8,728,556 - 18,156,361 = 10,146,542 blocks?

	Thanks for your help.

					Bill

ps. I have disabled compression with bacula, and the osst driver for my SC30
does not support compression.
