Cloud computing has been a huge-scale parallel with shared computing system. It comprises an accumulation of inter-related plus virtualized calculating resources which are managed to be one or more amalgamated calculating resources. The target of the survey is a mechanized evaluation or else explanation of proceeding events in cloud data replication system. Completely, 34 papers are accumulated...

Effective data management in today’s competitive enterprise environment is an important issue. Data is information; and information is knowledge. Hence, fast and effective access to data is very important. Replication is one such widely accepted phenomenon in distributed environment, where data is stored at more than one site for performance and reliability reasons. Applications and architectur...

herpes simplex virus (hsv) is one of the common pathogenic viruses of humans bing. this study aimed to determin anti-herpes virus activity of mentha piperita extracts in vitro. mentha piperita extracts can inhibit hsv infection when the cells treated before viral adsorbtion. hsv-1 were also inhibited by menthol after viral adsorption. hsv-1 viral particles were directly inhibited and viral yiel...

australian grapevine viroid (agvd), an apscaviroid of the family pospiviroidae, was recently identified in vineyards of southern iran. it had a relatively wide host range and caused stunting, leaf deformation, mottling and vein clearing in experimental hosts upon mechanical inoculation of nucleic acid extracts or agroinfiltration of the viroid infectious cloned dna. predicted secondary structur...

grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

In this article, we introduce a replication procedure in a distributed database system that supports several fragmentations of the same data table. One application that requires multiple fragmentations is flexible (similarity-based) query answering. The major feature of our replication procedure is that replication and recovery respect the overlaps of fragments stemming from different fragmenta...

Random replication is widely used in data center storage systems to prevent data loss. However, random replication is almost guaranteed to lose data in the common scenario of simultaneous node failures due to cluster-wide power outages. Due to the high fixed cost of each incident of data loss, many data center operators prefer to minimize the frequency of such events at the expense of losing mo...

Failures are usual rather exceptional in cloud computing environment. To access from the nearby site, the often used data should get replicated to multiple locations to compose the users to advance the system accessibility. A challenging task in cloud computing is to decide a sensible number and right location of replicas. At this point, we propose an adapted dynamic data replication approach t...
