  The notation where '%20' means a space applies to WWW
URLs, not shell filenames; tar won't respect it and the
shell won't reinterpret it.
  You've got two options here, depending which you think
is neatest. The quoting style is important in the first
case because of the way you want date's output used:

	tar cvpzf "/media/USB Flash Memory/partition1/EeePC$(date
+%F).tar.gz" --exclude=/media* --exclude=/proc/* --exclude=/lost+found/*
--exclude=/mnt/* --exclude=/sys/* --exclude=/home.* /
	tar cvpzf /media/USB' 'Flash' 'Memory/partition1/EeePC$(date
+%F).tar.gz --exclude=/media* --exclude=/proc/* --exclude=/lost+found/*
--exclude=/mnt/* --exclude=/sys/* --exclude=/home.* /
