  • 150k extension packages (292 revisions * 3 operating systems * 177 extensions)
  • Totaling ~800GB (one preview release ~900MB)

Retention Policy:

We plan to keep about 180 Preview releases (roughly 6 months’ worth).

Removal Plan:

At 9pm EST daily:

  • Remove 10 oldest Previews until 180 left
  • Then, remove one daily.
