Hello

The documentation for the on-tape-format is here:

http://www.bacula.org/2.4.x-manuals/en/developers/Storage_Media_Output_Format.html

and at first glance old tape from version 3.x should be readable and  
http://www.bacula.org/5.2.x-manuals/en/main/main/Bacula_Security_Issues.html#SECTION004310000000000000000
 also suggest  
so.

One thing to try is to only set the Maximum blocksize = 262144 and  
leave the Minimum blocksize at the default (0) to prevent Bacula from  
using *fixed* blocksize.

Regards

Andreas
