As I recall, teh AT&T Plan 9 project had an interesting filesystem/archival process that involved slowly migrating data from local "near off-line" storage (magneto-optical jukeboxes, IIRC).

The idea was that as files aged, they were migrated from local store (RAM) to local HD and on to jukebox for backup. As files were needed, they were called back from the MO jukebox into RAM and started their path back to the jukebox.

The key points in this (for me) was the lack of manual intervention to backup files,and the "always available" nature of files. Also, IIRC the Plan 9 clients were "typically" thin clients with minimal/no local HDs.

Anyway, just wanted to mention it...
