ArchivingΒΆ

When archiving is enabled through the relative preference, pings submitted to TelemetryController are also stored locally in the user profile directory, in <profile-dir>/datareporting/archived.

To allow for cheaper lookup of archived pings, storage follows a specific naming scheme for both the directory and the ping file name: <YYYY-MM>/<timestamp>.<UUID>.<type>.json.

  • <YYYY-MM> - The subdirectory name, generated from the ping creation date.
  • <timestamp> - Timestamp of the ping creation date.
  • <UUID> - The ping identifier.
  • <type> - The ping type.
