Backup Devices and Strategies Essay

There are many sub-groups of these discs, but the main types of discs are CD, DVD, and Blue-ray. The optical disc is placed into a DVD recorder and information is written to the disc. The data is written in contiguous format on the disc. A recorder will not write data to an optical disc if that data is bigger than the optical disc. A DVD disc can handle a data amount of 4.88 GB. The compression of an optical disc is handled by the program that is used to burn the disc. The data is written to an optical disc using a laser. This laser burns the data into the bottom of the disc. The use of different wave length of the laser actual help burn more data into the bottom of the disc. However, the drawbacks of an optical disc are that they cannot be placed in direct sunlight. The plastic that the disc is made of can warp in sunlight and corrupt the data on the disc. There is also the problem of scratches and dents making the surface of the disc hard for the laser to read.(AMERICAN,

Q5: Data storage capacity: Data stored on DVDs = 8.54 Gbyte = 8.54 x (1024) ^3 x8 =73358041415.68 =73.36 x10^9 bits Number of DVDs = (10^4kg)/15g = (10^4 x 10^3 g)/15g = (10^7)/15 =

List and describe at least three types of storage that is typically included in all computer systems.

Developing backup procedures, implementing company-wide, recovery plans need to be developed and offsite backup locations should also be considered

There are three types of storage devices. Magnetic storage devices store data as magnetic dots on spinning disks. These dots are written and read by an electromagnet. Examples of magnetic storage devices include Hard Drives (HDD) and Floppy Disks. Optical storage devices store data as coloured dots or small indentations on spinning disks. This data

For some computer owners, finding enough storage space to hold all the data they've acquired is a real challenge. Some people invest in larger hard drives. Others prefer external storage devices like thumb drives or compact discs. Desperate computer owners might delete

- Recommend against backup and DC to local disk. Instead recommend DC backups to NAS a multiple sites.

Hard Drive: A Hard Drive is a data storage device used for storing and retrieving data from the drive. It is also a permanent device. Hard drive is considered as internal storage. Hard drive is electromagnetic device.

A Primer on How to Create a Bullet-Proof Disaster Recovery Plan for the Entire Organization

Disaster recovery for a business goes further than backing up some tapes or disks and storing them in an off-site storage facility. Disaster recovery also involves making the business whole again, from retrieving the data backups after the disaster to restoring the data on the system, and opening the doors for business again with minimal loss of time, money, and reputation. This paper discusses the implications of a non-existent or inadequate plan for disaster recovery, with a particular focus on repercussions for small to medium-size businesses (SMBs). Traditional disaster recovery plans are discussed in terms of physical space required, costs of equipment needed as the business grows, and the time for recovery needed when a disaster occurs. The paper reviews the option of using the Cloud for disaster recovery. Specifically, the advantages of increased speed for data recovery, reduced equipment expenses, increased security, and scalability are discussed, along with any challenges to be faced when choosing the Cloud for disaster recovery.

Throughout the past recent years, the technologic community has advanced at rapid rates, generating changes in all domains of life. As technology brought more innovation in the lives of the Americans, it often forced out outdated products and replaced them with newer and higher quality items. One product which seems to be headed down this path is represented by the once very popular compact disc. The current project sets out to assess its position within the modern day society and to see whether it could have a more successful future in a different global region.

There was a time when the only place one can watch a movie was in a cinema. Then after a while, as technology progressed, more means were evolved. There were video cassettes first, followed by CDs. The reign of CDs lasted until the format DVD was carved out. Ultimately, this evolution resulted in the pinnacle of entertainment: the Blu-ray Disc. This research paper will look at the various reasons behind the development of both the DVD,HD-DVD and Blu-ray Disc and will analyze why Blu-ray Disc is better than its counterparts.

In 1998, The High Definition TV (HDTV) sets began to act in the United States and Japanese consumer markets. The old formats of media, such as DVDs and CDs were not able to store the amount of data necessary to record high-definition content. At the same time, the video game market was growing in a rapidly rate. The market demand generated after the success of DVDs pushed several companies to invest in this type of technology. In this framework, the company that would come up with an efficient innovation to provide higher data storage would have greater chance to have a big market share.

The experiments show that this technique can significantly reduce the transmission time of image files that have already existed in storage. Also the deletion rate for image groups which have the same version of operating systems but different versions of software applications is up about 58%.
