Report Can I backup to USB drive on ChromeOS? in Android Posted December 5, 2021 · Edited December 10, 2021 by devin07 On 5/1/2021 at 9:42 PM, ChrisChrisChris said: I am using Enpass 22.214.171.1245. In case of device failure, I want to backup mybkexperience vault to a USB thumbdrive. But the "External Storage" option is greyed out. Any ideas? There is no such feature of Chrome OS, I'm afraid.
