Yes, but how long can we expect the film to last?
Decades, if processed sloppily, or centuries, if processed archivally.
The availability and maintainability of the readout systems becomes, IMHO,
the deciding factor. If the data is stored as human-readable text this
isn't so much a problem, until languages change or are forgotten at least.

Sounds great, but how readily available is the process of film archiving

Unless the answers, in order, are extremely, extremely, very little, then
keeping the archive on mirrored servers is still the best solution we
currently have.
