error code received during backup

When I backup to the online backup for wordpress, it completes and says there was one error. This is the message in the event file. I don’t know how to fix it. Any suggestions? Thanks

File /home/content/22/5452222/html/stats/logs was skipped: Error happened at: files.php(1327)
filesize() [function.filesize]: stat failed for /home/content/22/5452222/html/stats/logs
