File Systems: Coda
	n Application transparent extensions of client and server – changes in the cache manager of a client – applications use cache replicates of files – extensive, transparent collection of data in advance for possible future use („Hoarding“) n Consistency – system keeps a record of changes in files and compares files after reconnection – if different users have changed the same file a manual reintegration of the file into the system is necessary – optimistic approach, coarse grained (file size)
