A method masking data failures, when a master copy of data is unavailable comprises storing a single master copy of data and a replica copy of the data; writing to the master using a middleware component; and reading from either the master or the replica using the middleware component, when the master copy is unavailable. When the master is unavailable, the writes are stored in a table located in the middleware component as stored write requests, in which the stored write requests comprise UDI's to be made to the master. The reads are also performed from the table and the replica when the master is unavailable. When the master becomes available, the stored write requests are propagated to the master. Thus, the middleware allows the writes to run during times when the master is unavailable.
