Ghost14 Understanding Bases/Sets

Hey guys, I'm a bit new to the ghost family of products, and I don't think I have a full grasp on a few things.

 

If I set Ghost to make a new Base Set weekly, does it essently need twice the room on the destination drive to make the backup? or does it do a consolidation of "snapshots" similar to VMWare?

 

For instance, I do not believe I have the room on the disk to have two complete backups on it, so I'm wondering if sets are not fesible for me.  If they are not, is there a way to consolidate the incrementals every so often to save space?

 

Also, is there a way to find out what files were backed up in the last incremental backup?  I seem to have some pretty large incremental files on disks where not much data changes, and I would like to see where the issue is.

 

Thanks much for all of the help!
