The afs vs nfs thread brought to mind a list of points I jotted down
earlier this year of features that I would like to see in a file system:
Properties of a desired file system
global
similar to AFS in this respect
high performance
separation of meta-data and data access
mixture of
no-cache
cache
file/directory staging
multiple residency (RO copies)
integrated with backup/archive/HSM
backup adds an additional residency
archive adds a long-term residency
transparent migration between levels
"snapshot" feature
secure
option for transport level encryption
option for storage level encryption
option for client level encryption
distributed administration
per-file policies
per-directory policies
per-user policies
per-group policies
delegation of administration as low as makes sense
wide availability (clients for a large number of architectures)
I expect to be waiting for quite some time ...
