I don't do daily backups. The only thing that changes that often is my 
email (I leave a copy on the server for anything I want to keep), and 
occasionally my accounts (gnucash) which is reconstructable from my 
other records (bills). Any work gets committed to the company svn 
repository.

Weekly is enough otherwise and most of my backups is mp3s 
(reconstructable from the CDs, but a *lot* of work) and jpgs (digital 
photographs, no prints to scan) for which the archives don't change 
except when I go on a tagging spree.

That works if you've got the upload bandwidth (which on $15/month DSL, I 
don't at home). Given the cost of bandwidth + online storage + DVDs the 
backup to external drive ($100 for 1TB these days, makes me feel old) is 
both faster and cheaper. One drive for local incremental backups and one 
(older, smaller) drive for a full backup for the offsite drive that gets 
updated less often.

Only one medium (hard drives), but I used all three copies recently 
after a drive failure while restoring from backup (losing the root-inode 
is bad - data was all there but lost a lot of file/directory names in 
the recovery process, backup #2 had the directories but was out of date 
on a few files). So I definitely recommend the duplicated copies.
