TM backup too large?

I am having the same issue. I did a fresh backup while connected and then I switched to Airdisk and tried to back up and it told me I needed X amount of space and only X left. It appears it wants to back up my whole drive onto the TM drive. Never asked to delete old backup.

If you move the drive from "directly connected" to your Mac to Airdisk, you MUST delete the old backups, as you will NOT be able to use them as Airdisk since the formats are different: folders for directly connected and sparse bundle for Airdisk. Reformat the drive as HFP+ Journaled and then connect it to the AEBSn. The first time it will backup the whole drive. To speed up that initial backup I recommend doing it with a direct ethernet cable to the AEBSn instead of using wireless.

When you say direct ethernet cable how do you do that?

Connect the ethernet port of your Mac to one of the three Ethernet Ports on the AEBSn or Time Capsule using a regular RJ45 ethernet network cable available at your local computer store for $5.

Try using an ethernet cable, either cat. 5e or 6. Also it depends if you are using 100 or 1000 bit connection with AEBS.
