CDP For Unix?

Has anyone heard of when (if ever) Continuous Data Protection for Files will be available on the Unix platform? I could really use this feature with my GPFS system. Since the application creates hundreds of meta data files daily and is proprietary (hence no TDP support) I am getting killed by the backup timeframe since the each volume has in excess of 4 million files already and incrementals take close to 48hrs. to finish. Anyone heard anything at symposiums or seminars?

  1. If you're worried about the length of the incremental backups, it seems like you'd be more interested in journal-based backups. This now exists for AIX (JFS2 only, I believe).

  2. My problem is that the filesystem in question is GPFS. So journaling is not an option.

  3. How does the time break out? Is all the time spent making stat calls?

    Is communication between the B/A client and the TSM server contributing to the 48 hours?

    What have you done so far to speed the process up?

  4. We have maxed out the transaction byte limit and groupmax settings, tuned the window size and use nodelay, but really there is only so much you can do. Using incremental-by-date is not really a solution and image backups are not supported.
