Time Machine on Extreme and Sparse Disk Images

I've got Time machine connected to backup to a drive connected to USB port of my new Airport Extreme; it is working, but stores all of its data in a sparse disk image-- are there implications as this file grows in size??

Very useful info on setting this up (and separating network into 802.11n and 802.11b/g access) at http://www.appleinsider.com/articles/08/03/31/exploringtime_capsule_wifi_802_11n_and_the_5ghzband.html

MacBookPro, Mac OS X (10.5.1)

This is normal when Time Machine backs up to an AirDisk setup. Same thing happens with Time Capsule backups.

No implications. If the whole disk is used for back up once the disk is about to run out of space the old time machine back ups will be deleted. This is standard behaviour
