Tapes ares still hard to beat for long term, low cost, off line 
storage.  But in our experience, moving between 3.5 and 5 GB of 
compressed data each day (database is running around 25-30 GB 
uncompressed at the moment), we have found hard drive space to be pretty 
cheap and vary reliable for local, and near local, relatively short term 
off line storage.  By short term storage, I mean that we keep a rotation 
of backup data on disk, aging it out and replacing it in turn with the 
latest set.  For added security, protection against disk failure can be 
accomplished by redundant copies on different disk.  Hope this helps.
