| 1. A method for maintaining data, comprising:
in a file system maintained by a client, marking the data as synchronize-always or local-always;
when the data is marked as synchronize-always, obtaining a portion of the data from a server in response to a process that
requests the data, the process executing on the client, the process originating the request, wherein synchronize-always indicates
the data has a size larger than an available storage size of a store local to the client such that the data is not maintained
on the store local to the client;
when the data is marked as local-always, obtaining the data from the store local to the client in response to the process
requesting the data, wherein data marked as local-always indicates the data cannot be removed from the store local to the
client, wherein the client determines where the data is obtained based on the marking of the data;
when the data is not marked synchronize-always and is not marked local-always, evaluating a local/remote attribute associated
with the data;
when the local/remote attribute is set to local to indicate the data is stored at the client, obtaining the data from the
store local to the client;
when the local/remote attribute is set to remote to indicate the data is stored at the server, obtaining the data from the
server.
