If using a recent version, check out "dumporder" and "taperalgo" in amanda.conf.
And if the two DLE's are on the same disk spindle, make sure they are not
backed up at the same time with a "spindle number" in your disklist.

AFAIK, the index is just a "table of contents" made by sending the dump
data through the same program(s) that created it.  There may be a bit
of stream editing, I'm not sure.  So assuming the dump was made by
tar and gzip, you should be able to do something like:

  $ <position the tape at the start of a dump file with mt>

  $ dd if=<tape device> bs=32k skip=1 |
       gzip -dc  |
       gtar tf - |
       sed 's/^\.//' |       # not sure, but I think a leading dot must be 
removed
       gzip > <indexfile of your naming>


Of course, someone else will probably say it is easier with amrestore
than separate commands, or there is already a feature to do this.
