• Question 102:

  In an EMC Avamar backup, what is the role of sticky-byte factoring?

  A. Determines which chunks are sent to the Avamar server

  B. Consistently creates 24 KB chunks

  C. Determines which files to chunk

  D. Consistently produces the same chunk result on unchanged data

  Correct Answer: D

  The Avamar agent running on the backup client (avtar) traverses each directory in the backup. For each file in the backup:

  1.

  Avtar checks the client's file cache to see if the file has been backed up before. Files that have been previously backed up are skipped from processing.

  2.

  If there is no match in the file cache, sticky-byte factoring divides the file data into variable-sized chunks.

  3.

  Each data chunk may be compressed.

  4.

  Each compressed data chunk is hashed. The hash created from a data chunk is referred to as an atomic hash. Atomic hashes are combined to create Composites. The number of composites equals the depth of the file system being backed up.
