Backrest representation of sizes reported by restic may be misleading #433

Closed digicommons closed 3 months ago

digicommons commented 3 months ago

Describe the bug Restic outputs sizes in units based on powers of 2 (e.g. KiB, MiB, GiB etc.). Backrest on the other hand seems to report these exact values with the unit symbol for units based on powers of 10 (e.g. KB, MB, GB etc.)

To Reproduce

  1. View past or running backups on plan page as well as detail component of a running backup.
  2. Compare reported size to size of remote (e.g. 2.33 TB on Backrest vs. 2545 GB on Backblaze)

Expected behavior Backrest should either display the unit symbols that restic uses (KiB, MiB, GiB etc.) or convert the values that restic provides to units based on powers of 10 and use the corresponding unit symbols (KB, MB, GB).
