A new, easier window. How copies work and what lands on your drives stay the same.

The new window

New

  • A new window: a sidebar with one area each - Backup, Drives, MD5 check and Settings - and a status bar at the bottom. Drives, MD5 check and Settings are pages of the main window now instead of separate windows. The tray icon and its menu work as before.
  • Progress under the drive list, with two bars: the file being copied and the whole run.
  • Changes on the Drives and Settings pages wait for Save; Undo changes goes back, and leaving a page with unsaved changes asks first.
  • Recording checksums after a copy shows its progress (file, files and bytes done, rate, time left).
  • New setting on the MD5 check page: Record checksums after each copy (on by default). Off, a copy ends sooner, and Verify drive records the missing checksums later. Nothing is lost.
  • Checksums are about 1.6 times faster in the download (built with full optimization).
  • With the window open, plugging in a drive says so in the status bar and flashes the taskbar button; a drive that goes away is said too.
  • The window opens when Offline Backup starts, so it is plain that it is running; closing it keeps it in the tray. Start it with /tray to start in the tray only. /show is no longer needed.
  • About Offline Backup... in the window's title-bar menu (the icon at the top left, or Alt+Space).

Full list: CHANGELOG.
