I have an Airport Extreme Base Station (AEBS) current generation with the latest firmware. I have a Drobo (latest firmware) and three drives connected to the USB port.
I have formatted the Drobo drives using HFS+ in single partition and marked the partition as GUID.
I have then used TimeTamer to create a sparsebundle. The readme file shows success and I can see the file when I mount the drive in Finder. Thus I can connect to Drobo over WiFi using the AEBS. I can copy a file to the share and confirm it’s ok.
I then enter Time Machine and select the drive as the Time Machine destination and start the Time Machine backup. Which fails.
The Console Log shows the following error message :
08/11/2010 22:17:50 com.apple.backupd Backup failed with error: 19
The goal is to perform Time Machine backups over wireless to the AEBS.
Can anyone give any pointers as to where I’m going wrong.
