Receiving the following error message when attempting a backup through the CUE GUI interface, "Connection to backup server failed: 550 can't create directory. Permission denied."
CUE is reaching the correct FTP backup directory because the history.log file was placed in that directory. Not sure if it has something to do with the FTP software we are using - FileZilla.
Normally we require it to be able to create directories in the path specified as the backup location. I think minimally it will create a Configuration_1 and Data_1 directories (the number could be incremented up to however many backup instances you have configured; by default 5, I think). The best thing to do would be to check the filezilla logs to see what it tried to do when it was denied and then create those directories.
