First, if you use rsync, full backups just compare data and send 
differences - and rebuild the tree for the next comparisons.

With tar and smb as the xfer methods, incrementals go by the timestamp 
only and won't catch deletions or old files in their new location under 
renamed directories so your backup drifts out of sync.  With rsync, the 
comparison is done against the previous full and the changes become 
larger and larger on each run unless you do incremental levels.  If you 
do incremental levels, the server side work of merging the trees for the 
comparison base grows as you add levels.
