Storage Spaces Tiers optimization - how to disable totally ?

hello,

is storage spaces tiering optimization happens automatically storage spaces thinks has done ?

in server have set "storage tiers optimization" task in task scheduled run every saturday 13:00 , if @ tasks jobs history see so.

ps c:\windows\system32> get-scheduledtask -taskname *tier*  | get-scheduledtaskinfo

lastruntime        : 2014-06-28 13:00:00
lasttaskresult     : 0
nextruntime        : 2014-07-05 13:00:00
numberofmissedruns : 0
taskname           : storage tiers optimization
taskpath           : \microsoft\windows\storage tiers management\
pscomputername     :

but if @ event viewer - windows\storage-tiering\admin log see beside saturdays optimization jobs happens several times week.

why happens ? how stop happening ? looks if make lot of writes @ night starts optimize.

need stop because unknown reason if dpm starts backup vm server while tiers optimization running - vhd's vms gets read only. 

hi,

i reply below storage space team.

in windows server 2012 r2, in majority of skus, default there 2 tasks trigger storage tier optimization:
1. defrag task - found under \microsoft\windows\defrag
    task runs on weekly basis.
2. storage tier optimization - found under \microsoft\windows\storage tiers management
    task runs on daily basis.
 
apart above 2 tasks, if user runs "tier optimization task" manually, using "defrag.exe /g flag" or "optimize-volume -tieroptimize" cmdlet, windows log event in event viewer when optimization task completes.

please check if running optimization task manually or if seeing optimization result part of "defrag weekly task" mentioned above?

regards,

mandy
