Any Reasons NOT to use automatic with incremental synchronization sync type
Situation: Have an active and standby pair on 5200 boxes/13.1 release. ~ 300 VIP on LTM, 20 APM policies, 50 ASM policies. Several of ASM policies with policy building in automatic mode. We have auto failover turned on if Primary goes down but Not configured to auto failback on standby device. Those items noted...
Are there any concerns about using automatic with incremental synchronization sync type? Two potential pitfalls I could see are the following a) Policy building in auto mode will result in more ASM Policy updates and trigger more syncs. Question - Will every change to counter result in policy update? b) Maximum Incremental Sync Size is 1024, and if more, will due a full syncronization. How can one determine what the sync size is for a given syncronization due to an individual ASM, LTM, or APM change?
I would prefer to use auto sync if possible to ensure backups are as up to date as possible but anecdotally am not aware of many shops using auto sync. Welcome community's thoughts on the matter. Thanks.
