How are files counted against my included storage
For every storage tier (live, archive) scoopa calculates the monthly storage peak once per hour.
All files that are live, including files in the trash and files restored from archive, are counted towards the live tier.
Each file that is uploaded to scoopa is automatically in the "live" storage tier for at least 7 days. (exception: direct-to-archive).
After 7 days the file can be transitioned into the archive tier or can be moved to trash. Files in the trash will remain there for 7 days. The trash cannot be emptied by hand. Contents in the trash will not be billed again in the next month.
Example
If you upload 100GB on the first day of the month in the professional subscription, you can archive all of it automatically after 7 days and again upload 100GB (and so on, and so on...) without going over your 100GB of included storage. However if you upload 150GB you will be billed 50GB overusage for this month, regardless of how long you were over the limit.
Pro-Tip: You can make sure to stay in your included storage. Read more about that in the Cost-Control article
