Not a chance. Takes too long to upload and download and the 'cloud' data usage and rights assignment stuff is pretty unclear. My father (a pro) has about 3TiB on a NAS and AIT backup.
Tapes are manually archived off site in a safe deposit box monthly. A month window is an acceptable loss.
Agree entirely. T'was an idiot company I worked for at the time that stored their backups in the basement of the World Trade Centre. Yes that worked out well...
