Hello, @sgm . Unfortunately, this error alone doesn't provide enough information to suggest what might be causing the issue. Please inspect the backup log and let us know what's logged in it.

Thank you. Could you please review the scheduled tasks for the account you are trying to backup and double-check if there are any cron jobs with unrecognized characters?

Indeed, there was a strange character in one of the scheduled tasks. The backup is now working correctly.Thank you.
