ITERATE ENTIRE HISTORY: Unknown error: 0

[Siju George]

Hi,

I update a particular file from my Desktop to the dfly server using rsync.
I created the file some days back and updated it today using rsync.

While I tried to get revisions of the file I got these messages.

dfly-bkpsrv# undo -i DailyDevotions-Volume1.doc
DailyDevotions-Volume1.doc: ITERATE ENTIRE HISTORY: Unknown error: 0
dfly-bkpsrv# undo -i DailyDevotions-Volume1.doc
DailyDevotions-Volume1.doc: ITERATE ENTIRE HISTORY
        0x0000000130d20dc0 14-Sep-2009 13:59:18

why did I get the unknown error at first?
and why the first version of the file is not shown?

My snapshots configuration is

dfly-bkpsrv# cat /Backup1/Data/snapshots/config
snapshots 0d 1m
prune     1d 60m
reblock   1d 60m
recopy    30d 60m

Thanks
