RESUMEN

Distributed configurations, where nodes may act independently, offer potential for fault tolerance through data replication. On the other hand, they imply an additional complexity to maintain information consistency.

This work proposes a replicated multiversion file server that aims to provide high data availability and operation atomicity. The file server explores the potential of distributed architectures and, at the same time, avoids that inconsistencies make system utilization more difficult. In order to measure the complexity in system design, a prototype of the distributed file server was implemented.
