Bacula already requires OS support.  It relies heavily upon SCSI 
interfaces.  These interfaces are not designed specifically for Bacula. 
  They are available to all comers.

At present, Bacula knows about tape, via SCSI.  In general, it does not 
care if that tape drive is DLT or DAT (for example).  Both devices are 
accessed through the SCSI interface.

This is why Bacula does not directly access any tape device.  It uses 
the SCSI interface. By relying upon the SCSI interface, Bacula is more 
independent.

A SCSI interface to Amazon S3 may not be the only answer to this.  It 
might also be possible with plugins, a relatively new feature in Bacula. 
  But I suspect that plugin is for sources only (i.e. bacula-fd) not for 
sinks (bacula-sd).  Hopefully, someone else knows.

Someone else mentioned: fuse plugin.  this looks promising: 
http://code.google.com/p/s3fs-fuse/ it's obviously linux specific, but 
should be pretty trivial to set up with bacula

Kern also has an idea.  See his recent post.
