No, that case of archiving documents and communications to fulfill legal 
requirements is called an _archive_! And while such a thing works well on 
paper (and for paper-documents, provided you are good friends with the 
archive-lady), try to access any old electronic n a company after they 
switched from lotus to SAP in between. Still the data is archived according to 
the law.

No one wants a backup. Everyone only wants restore.

Good thing backuppc can do backups that don't get in your way, restore that 
works simply by clicking in a web-interface and additionally write complete 
dumps to archive-media...

Have fun,
