[OpenAFS] file magic of backup file

[Markus Hetzenecker]

hi all

i would like to know the file magic (the first bytes) of an openafs backup with output to a file.
a grep in the sources doesn`t show me the piece of code 
the first 16 bytes of my backupfiles are like

00000000  41 90 ab 09 00 00 00 04  40 24 5c a1 41 de 03 21  |A.«.....@$\¡AÞ.!|
00000000  41 90 ab 09 00 00 00 04  40 6d e5 2b 41 af a1 3b  |A.«.....@må+A¯¡;|
00000000  41 90 ab 09 00 00 00 04  40 77 07 ac 40 c7 73 2c  |A.«.....@w.¬@Çs,|

well, the magic seems to be "41 90 ab 09", and the rest bytes?
the backup is generated by "backup dump", butc (and a (un)mount script (for compress with rzip and archives at tivoli))

and  as always, thanxs to the people of openafs.
THX, markus.
