How often to do Active Fulls alongside synthetic fulls?

Post by wa15 » Sep 12, 2016 4:14 pm

I am currently doing forward incrementals weekdays and synthetic full on weekends. Can someone help me understand what the benefits of active fulls in my case would be?

As far as the backup chain length is concerned, I believe that would not be an issue since the synthetic full "resets" the chain, correct?
Would active fulls be less fragmented (and thus take up less space) than a synthetic full?

Any other information is appreciated.

Hi Farshid, your understanding is correct. Generally speaking, while being very taxing on production storage, active fulls put much less load on the target storage (no random I/O) and allow to avoid backup file fragmentation. In terms of the chain length they act similarly to synthetic fulls, resetting the chain. Here's also a good reading regarding this matter.
