How important are your data to you?” “What would happen if . . . ?” While business managers focus on solving business problems and determin- ing what their information systems should do, di- saster recovery consultants ask what would happen if things go wrong.

With careful advanced planning, disaster recovery specialists help their clients prevent calamity. While this topic covers a wide variety of software issues, installation configuration issues, and security threats, examining common end-user mistakes may also prove enlightening. Common end-user mistakes include:

a. Failure to save work in progress frequently.

b. Failure to make a backup copy.

c. Storing original and backup copies in the same location.

For each of the common end-user mistakes listed above, answer the following questions.

a. How might this mistake result in data loss?

b. Wha tprocedure scould you follow to minimize this risk?

Answer:

How might this mistake result in data loss?

a)Failure to save work in progress frequently: When you are working on computer for examplem ms word you must keep on saving the information side by side otherwise if there is a power failure and the battery is not working everything will be lost whatever we have worked till now and we will have to start it from the beginning. It results in an entire data loss.

Asingle power outage, surge, or spike can damage expensive electronic components and result in critical data loss. Consistent surges and brownouts, meanwhile, shorten the lifespan of computers, printers, network components, and other equipment.

b)Failure to make a backup copy:

if there is a power cut and there is no back up of the files or data we are working on then entire data entered will be lost if it has not been saved. backup copy requires training to the programmers to create backups of the files and database. If they are unable to create copies of them then it could lead to loss of data which might be crucial for the company or a project to be delivered on time and due to no back up ,the engineer will have to start from the scratch.

Insufficient training, as a consequence, many processes including backups, repetitive data entry, complicated calculations, and automated data selection are completed manually, which introduces a greater likelihood of errors

C)Storing original and backup copies in the same location:

If they are present on a single harddrive or disk that crashes then the entire data including the backup will be lost. As a result neither the original data nor its backup will be available to the programmer or the user resulting in huge loss for the company and the user will have to start creating files or database from the scratch since there will be complete backout of data.

What procedure scould you follow to minimize this risk?

a)Failure to save work in progress frequently: create backup copies for the work and keep saving it side by side while you are working.Organizations should deploy quality battery backup devices (with built-in surge suppression) for all critical desktop PCs. Further, technology professionals should connect all servers to uninterruptible power supplies and test them regularly to confirm adequate failover protection is in place.

b)Failure to make a backup copy.:

->Full backups

The most basic and complete type of backup operation is a full backup. As the name implies, this type of backup makes a copy of all data to another set of media, which can be tape, disk or a DVD or CD. The primary advantage to performing a full backup during every operation is that a complete copy of all data is available with a single set of media. This results in a minimal time to restore data, a metric known as a recovery time objective (RTO). However, the disadvantages are that it takes longer to perform a full backup than other types (sometimes by a factor of 10 or more), and it requires more storage space.

Thus, full backups are typically run only periodically. Data centers that have a small amount of data (or critical applications) may choose to run a full backup daily, or even more often in some cases. Typically, backup operations employ a full backup in combination with either incremental or differential backups.

->Incremental backups

An incremental backup operation will result in copying only the data that has changed since the last backup operation of any type. The modified time stamp on files is typically used and compared to the time stamp of the last backup. Backup applications track and record the date and time that backup operations occur in order to track files modified since these operations.

Because an incremental backup will only copy data since the last backup of any type, it may be run as often as desired, with only the most recent changes stored. The benefit of an incremental backup is that they copy a smaller amount of data than a full. Thus, these operations will complete faster, and require less media to store the backup.

c)Storing original and backup copies in the same location.

an offsite copy or online back up can be created which can be accessed with a username and password and data can stay on the web all the time and doesnt get lost. Or we can create a copy on the other hard drive or disk so that if one gets damaged another one can be used and data can be retrieved in the best possible way and the shortest time possible
