Data Backup and Disaster Recovery - The Basic Difference

1. Data Backup and Disaster Recovery - The Basic Difference Disaster recovery and Data backup might look same to a layman but they are very different concepts, disaster recovery is not possible without backup in the first place. Backup data is historically collected data making redundant copies of data. Disaster recovery on the other hand, is all about how backups and other fault-tolerant mechanisms are put to work after a disaster occurs. Disaster recovery is having the tested withheld data to get systems restored and running as quickly as possible, as well as the associated data. The need for Data recovery and backup in a data center: Data recovery is the process of restoring data that has been lost by mistake and important files are deleted , File system format or Damage and files corrupted or made inaccessible for any reason. That could be anything and there are many reasons to data loss ranging from a disk crash on a user’s device to a data centre crushed by a meteorite. When such a failure happens, it is not just data that needs restoring, but the full working environment; in other words, disaster recovery.

2. Robust methods employed in a data center for Data Recovery and Backup: Data backup simply means a copy of your data is replicated to another device or location. When your system data gets deleted and the system is formatted either by mistake or data has not been saved before formatting. Generally your file size in clusters is commonly 32 KB, but it varies with drive size. But if your data is large and files are larger you need data recovery software. Recovery data is divided into two categories: Data required keeping current values.2) Data to make the restoration of previous values possible. Possible Levels of Recovery: • Data recovery to the correct state.• Recovery to a check pointed correct state.• Recovery to a possible previous state.• Recovery to a valid state.• Recovery to a consistent state.• Crash resistance (prevention).

3. The benefits of having your data secured in a data center: • Data center provides security to protect sensitive data from hackers.• Data center provides Disaster recovery service.• Data center and data secured are protecting sensitive data from corporate sabotage.• Data center provides physical security of your data.• Data center is protecting your data and keeps your business operating at all times.• Data center provides and manage all of the network technology and business needs Article Resource: http://maximumtechnology.tumblr.com/post/125746389090/data-backup-and-disaster-recovery-the-basic
