Why media libraries outgrow initial estimates

New formats, higher-quality files, artwork, subtitle tracks, and an additional backup copy can quickly make a current-library total misleading. A reserve keeps expansion from becoming a last-minute migration.

Action checklist

  1. Measure the library you intend to keep.
  2. Choose the number of truly separate copies.
  3. Plan an upgrade before the primary target reaches 80% used capacity.
  4. Test whether files can be restored from the independent copy.
