Arkeia Network Backup Version 9.1 Change Dedupe Block Sizes Used

From Arkeia Documentation

The DEFAULT_BLOCK_SIZE parameter is set to "65536" in v9.1.4 and is not listed in the dedupe.prf file.
Setting this value in dedupe.prf over rides the default of 64k block size which is pre compiled in Arkeia.

 DEFAULT_BLOCK_SIZE      "32768"

The DEFAULT_BLOCK_SIZE is the deduplication block size (in Bytes) used to dedupe file types that are not specifically
listed in the BLOCK_SIZE_1024, BLOCK_SIZE_2048, BLOCK_SIZE_4096, BLOCK_SIZE_8192, etc... parameters in the arkdedup.prf file.

The block sizes can be adjusted from the default for testing and analyzing the best setup for your environment.
Edit the dedupe.prf file and force Arkeia to ONLY use the "32k" default block size or a default block size of your choice.

vi /opt/arkeia/dedupe/dedupe.prf

# The deduplication block size (in Bytes) to use to dedupe file types that are not
# specifically listed in the BLOCK_SIZE_1024, BLOCK_SIZE_2048, BLOCK_SIZE_4096
# or BLOCK_SIZE_8192 parameters

DEFAULT_BLOCK_SIZE      "32768"  # <--- the presence of this value overrides the default of 64kB which is pre-compiled.

#BLOCK_SIZE_1024        ""
#BLOCK_SIZE_2048        ""
#BLOCK_SIZE_4096         "txt, doc, xls, ppt"      # <--- comment out the 4 kB block size to force all files to use the DEFAULT_BLOCK SIZE
#BLOCK_SIZE_8192        ""
#BLOCK_SIZE_16384       ""
#BLOCK_SIZE_32768       ""
#BLOCK_SIZE_65536       ""

:wq!

Now the dedupe operation will only use a single block size of 32 KB.
