In cloud storage systems, users must be able to shut down the application when not in use
and restart it from the last consistent state when required. BlobSeer is a data storage …

The amount of data stored in modern data centres is growing rapidly nowadays. Large-scale
distributed file systems, that maintain the massive data sets in data centres, are designed to …

Checkpointing and rollback recovery are established techniques for handling failures in
distributed systems. Under synchronous checkpointing, each process involved in the …

Given the ever-increasing size of supercomputers, fault resilience and the ability to tolerate
faults have become more of a necessity than an option. Checkpoint-Restart protocols have …

This paper presents the fault tolerance and replica synchronization among storage server
(Data-node) without the interference of metadata in Hadoop. It employs chunk list data …

We propose a method to incorporate coordinated checkpointing and rollback in high
performance computing applications on massively parallel computers. A library allows the …

A consistent checkpointing algorithm saves a consistent view of a distributed application's
state on stable storage. The traditional consistent checkpointing algorithms require different …

Coordinated checkpointing simplifies failure recovery and eliminates domino effects in case
of failures by preserving a consistent global checkpoint on stable storage. However, the …

The cloud computing has successfully facilitated many cutting-edge studies including
Internet of Things, Big Data, and many others in recent years. The accomplishment of cloud …

The ability to take snapshots is an essential functionality of any file system, as snapshots
enable system administrators to perform data backup and recovery in case of failure. We …
