About two weeks ago my Kopia backups using rclone to OneDrive started failing with an error similar to this one:
ERROR open repository: unable to open repository: cannot open storage: unable to start rclone: rclone server failed to start: <DATE> <TIME> CRITICAL: Failed to create file system for "<REDACTED>": failed to get root: Get "https://graph.microsoft.com/v1.0/drives/<REDACTED>/root": couldn't fetch token: invalid_grant: maybe token expired? - try refreshing with "rclone config reconnect Mastodon:"
Backups have been running fine for months, so automatic refresh did work before.
Since I couldn’t figure out how to run rclone config reconnect in the Kopia Docker container (0.20.1) I created a new Rclone connection on my Mac and copied its refresh token to Kopia’s rclone/rclone.conf file on the VPS that I’m using the Kopia Docker container on. However, today (about a week later?) I’m running into the same error again, so it’s time I learn how to do this properly…
How can I run rclone config reconnect in my Kopia Docker container?
And maybe related, why is automatic refresh failing suddenly? How to fix that?
