sm_wipe -	Wipe. This is a volume cleaner. It removes expired video/audio chunks accordingly with retention policies

sm_dc  -	Decimator. This a special process for removing slices for FRD schemas accordingly with decimation schedule in retention policy

sm_sk  -	Space Keeper is dedicated process for maintaining space utilization. It assigns available volumes to storage consumers (retrievers). Space Keeper also calls a Wipe and Decimator hourly and in case of space shortage
