Downgrading to Arq 4

If you've already done a backup Arq 5, you cannot switch to Arq 4 because Arq 4 can't read backups created by Arq 5.

To switch from Arq 5 to Arq 4:

  1. Quit Arq 5.
  2. Delete the Arq 5 app from your computer: On Mac, drag the app to the trash. On Windows, go to Add or Remove Programs, select Arq 5 and click Uninstall.
  3. Delete Arq's configuration folder. On Windows this is C:\ProgramData\Arq. On Mac this is ~/Library/Arq. (To get to your Library folder, go to the Finder, hold down the Option key, and pick "Library" from the "Go" menu.)
  4. Download and launch Arq 4.
  5. Configure Arq 4 with your destination information.
  6. Find your computer in the "RESTORE FILES" section in the main window. Select it. Then click the "Adopt This Backup Set" button to reconnect Arq with those data/settings.
