The initial piece scan is the biggest process that goes over all pieces. There are still 2 other processes that will do something similar.
- On startup and every 24 hours a cleanup job will run over all pieces in the trash folder and delete pieces that are older than 7 days.
- Executing garbage collection (triggered by a message from the satellite) will run the filewalker over all pieces for one satellite.
