Errors showing up in the logs and email notifications indicating that there was a problem with the backup, even though it seems to have completed successfully.
"EGP Backup Notification Partial Failure"
The EGP Backup was successful.
An error ocurred sending the backup to archiveserver(firstname.lastname@example.org) via FTP."
If the backup is being generated properly and the archiving is functioning properly, then these errors can be safely ignored.
One workaround is to try using SFTP or SCP instead of FTP to see if this will stop the false positive errors.
