  Abstract:   Storage space shortage can be solved either by deleting unneeded files or by adding additional storage. Most of the time, the fastest way to solve the problem is to move data on external storage. This paper continues previous workon solving such situations automatically, transparently, and using as external storage a peer-to-peer file system. The current work addresses performance and data availability issues raised by the costly network activity and the peer-to-peer system lack of guarantees. The proposed solutions rely on the integration of the system with the BBUFs file system for performance improvement and on apredictive algorithm for choosing the "victim" blocks to be moved to external storage (BBUFs).

Key words and phrases. distributed file systems, peer-to-peer systems, storage limitation.
