Briefly describe differential backup. What are some of the advantages and disadvantages of using differential backup?

A differential backup is the storage of all files that have changed or been added since the last full backup. Theadvantage is that it reduces the space requirement and time to the backup but the downside is that if an incidentoccurs multiple backups are needed to restored to restore a system.

The market for consumer-grade tape backups has dwindled to a fraction of its former popularity in the last decade.What are the primary drawbacks of tape backup?Primary drawbacks of tape backup are the cost of specialized hardware to read tapes, cost involved in storing tapesand reliability to restore from the tape.

Even the best backups are inadequate unless they can be used to successfully restore systems to an operational state.What are some of the questions that must be answered by a backup and recovery plan?

Each backup and recovery setting should be provided with complete recovery plans, including testing and rehearsal.

One strategy for implementing server recovery and redundancy through mirroring servers uses hot, warm, and coldservers. Explain how this strategy works.In this strategy, the online primary server is the hot server and it provides the services necessary to supportoperations. The warm server serves as an secondary server and services request from primary when it is down orbusy. The cold server is the administrator's test platform and should be identically configured to the hot and warmservers. This is used to test new patches and avoid hot server going down. Should the hot server go down, the warmserver takes over as hot server as the hot server is bought up.

What is the difference between remote journaling and electronic vaulting?

E-vaulting is the transferring bulk of data in batches to an off-site facility whereas remote journaling transfers livetransactions to an off-site thereby recording all changes.

Briefly explain how database shadowing works.Database shadowing, also known as data bank shadowing, is the storage of duplicate online transaction data, alongwith the duplication of database at the remote site to a redundant server.

Database replication focuses on the backup of multiple copies of the database for recovery purposes. Briefly describethree types of database replication.The 3 types of db replication are :1. Snapshot replication: Copying data from one database to another2.Merger replication: Merging data from multiple databases into a separate database.3. Transaction replication: Using a master db for regular operations but periodically copying new and updated entriesto a backup db.

Using virtualization, an organization can take its existing hardware and deploy any other operating system and/orapplication. There are several different levels of virtualization. Describe one of these: application-level virtualization.

This method virtualizes the OS layer so as to look to the application as the the expected OS, answering all necessaryapplication programming interface(API) call made by the application. The application perceives that it is interactingwith the host OS and the resources managed by it. This method is used to run application intended to run on non-native OS.

Explain how a mutual agreement would work as a shared-site resumption strategy.A mutual agreement is a contract between two organization for each other to assist the other in the event ofdisaster. This allow the organization to use the resources of the other without investing in hardware forincidence/disaster recovery. It allows for the organization to save a lot of resources for disaster recovery but islimited to the level of agreement and investment of resources from the other.
