Backup and Recovery
Published in Preston de Guise, Data Protection, 2017
Server-initiated backups refer to the backup server software on the “master” server starting the backups for one or more hosts at a designated time. Almost all backup software contains backup scheduling capabilities that allow backups to be started at nominated times. The advantages of server-initiated backups cannot be overstated: they give the backup administrator control over the timings of backups, which directly affects the resources available to the backup server to provide those services. When a backup server initiates the backup process, it should have an accurate understanding of what resources will need to be allocated to allow the backup to complete and an understanding of what resources are available based on other activities executing at the time. Furthermore, centralized timing and scheduling of backups are critical in reducing administrative overhead in the backup environment.
Protecting Virtual Infrastructure
Published in Preston de Guise, Data Protection, 2020
To put it mildly, backup software—particularly traditional backup software—is always designed to be a resource hog. A fundamental purpose of backup software is to generate a protected copy of data as quickly as possible (or likewise, recover from that copy as quickly as possible). It is not uncommon to see poorly designed backup environments using in-guest agents to saturate many, if not all, resources within hypervisors: storage IO, network bandwidth, and CPU utilization. This of course violates a fundamental requirement of a backup and recovery system: to not unduly interfere with core operations in order to perform data protection.

This approach has many advantages that are: Facilitate the maintenance process and the availability. (estimation of the RUL leads us to take the maintenance decision at the right time and thus avoid the failure).Ensure the continuity of the machines operation.Maximize power of data processing.Increase memory space of storage data.Decentralize the sites involving in the PHM domain.Share the experiences of PHM providers.Personalize the PHM solutions.Minimize the maintenance cost.Improve the QoS.Offer the prognostic as a service in the cloud computing. By using this system, the company no longer owns the used server because it is made available by its provider. However, it can progressively access many services without having to manage the underlying infrastructure, which is often complex (database maintenance, data backup, software update, server maintenance, etc.). Applications and data are no longer on the local computer, but on the ‘cloud’ which is a set of interconnected remote servers using high-performance internet links essential to the fluidity of the system. Access to the service is through a software application or an internet browser on the company’s computers and easily available.
