Because snapshotting uses so much less space?

So much so that, for normal usage, I probably have no need to delete any 
snapshots, for YEARS?

Okay, space is not an expensive commodity, and you don't want too many 
snapshots, simply because digging through all those snapshots would be a 
nightmare, but personally I wouldn't use a crude rsync simply because I 
prefer to be frugal in my use of resources.
