Know which records you are viewing
Fastly separates the main history from archived sessions. Both collections can remain on the device, but only main history feeds the standard session summaries and weekly display.
Make the smallest useful change
Use main history for the records you want included in everyday review. Use the archive for retained records you intentionally want outside that view, such as a labeled interface test.
Archive is a separate retained collection. Main-history session totals and current rhythm read the main collection, while JSON backup export includes both main history and archived records.
Verify the result
An export includes both main history and archived records. Archiving therefore changes visibility and summaries rather than stripping that information from a backup.
Preserve an honest history
Document your own reason for archiving if it matters. Two ledgers with the same visible total can contain very different excluded records, which changes what a summary represents.
