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:
- Quit Arq 5.
- 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.
- 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.)
- Download and launch Arq 4.
- Configure Arq 4 with your destination information.
- 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.
