    Hi, Ember

    Thank you for good blog.

    What do you think about DB2 backup’s deduplication ? Is this good idea ?
    Im ask because if I right understand (may be I’m wrong) in deduplication case we fully depend on first full backup and any problem with this “master” backup resulted in lost of all next backup’s chain.

      I’m sure it depends on the deduplication solution’s details. I don’t know how often it would regenerate any deduplication dictionary or whatever you call it. Even if it does use only one full backup for the patterns, think about how similar a database often is from one backup to another. Maybe 1% of data changes, which may add up over time. Honestly, I haven’t delved into the details of deduplication.
