Hi folks,
the question came up whether there are any guidelines on what type of files and which applications profit from a better dedup ratio using variable length segments or is it purely trial and error by evaluating the job details etc?
Any comments are appreciated :)

Hi bert_geiger
I don't think anything has changed from fixed block deduplication besides you will get a slightly better dedupe ration using variable length dedupe on the cost of more CPU usage.
The deduplication has a instruction on monitoring efficiency : Monitoring the MSDP deduplication rate | Monitoring deduplication activity | Veritas NetBackup™ Deduplication Guide | Veritas™
You could set up two test MSDP pools, and then backup the same data twice, one with variable and the other with fixed with dedupe.
Hi Nicolai,
so it is trial and error...
But thanks for the reply :)
Regards, Bert
