Re-Enable Retention Policy
When we put in EV about 7 years ago, the majority of the mail we captured via journaling was put in a three year retention policy. However, not too long after we were up and running our compliance people asked us to turn off the policy enforcement (long story).
I am now getting the OK from compliance to enforce the policy. When we turn this on, I would imagine a good portion of the 8TB of data we have in Centera will be over three years old and will be purged. Should I expect to see a big impact on system performance? Just curious...
Yes, it will be absolutely
Yes, it will be absolutely massive
My suggestion is make it so that the retention is 6 years
then enable expiry, let the data delete and monitor the resources and see how it performs
Then as you progress switch it to 5 years , and then let it delete then 4 years , then 3 years etc
Otherwise you risk more time performing expensive SQL Queries, consuming lots of memory and not deleting much at all if you just try and blast the whole hog straight away
