And what code did you use to transform your sample input into your sample output?
The title of this thread says you want to delete duplicate records. What constitutes a record? (A line, a create x {...} where x is the same in both records, or what???)
You have shown us your input file and you have shown us what seems to be incorrect output that you're getting from your code. What output do you want?

AMDD(8) System Manager's Manual AMDD(8)
NAME
amdd - Amanda version of dd
SYNOPSIS
amdd [ -d ] [ if=input ] [ of=output ] [ bs=blocksize ] [ skip=count ] [ count=count ]
DESCRIPTION
Amdd provides just enough of the standard dd command for the needs of Amanda. This is handy when doing a full restore and the standard dd
program has not yet been found.
Amdd also provides access to the Amanda output drivers that support various tape simulations. This may be used for debugging or to convert
from one format to another.
See the amanda(8) man page for more details about Amanda. See the OUTPUT DRIVERS section of amanda(8) for more information on the Amanda
output drivers.
OPTIONS
-d Turn on debugging output.
-llength
Set the output length. If the output driver limits the output size, this controls when end of tape will be simulated.
Length may have a multiplier suffix:
k 1024 (Kilobytes)
b 512 (Blocks)
M 1024*1024 (Megabytes)
The default is no multipler (bytes).
if=input
Input to dd. Default is stdin.
of=output
Where to send the output of dd. Default is stdout.
bs=blocksize
Size of each record. Input records smaller than this will not be padded. Output records will be the same size as the corresponding
input record. Default is 512 bytes.
Blocksize may have a multiplier suffix:
k 1024 (Kilobytes)
b 512 (Blocks)
M 1024*1024 (Megabytes)
The default is no multipler (bytes).
count=count
Number of records to copy. Default is all records until end of file.
skip=count
Number of records to skip before copying input to output. Default is zero.
