Explain why it is important to make backups of your data?

How do backups protect files from loss?

In case of disaster, you should always have backups of important data. Memory sticks and disks make is a very good way for storing significant work on.

Why should backups be stored off site and periodically tested?

If the initial location is damaged, like if there was a fire in the building that the computers were stored, then the on-site backups would be lost. For companies with significant amounts of very important data, it is essential that this data is safe. If they have more than one site with computing capacity, then it makes sense to have off-site backups. They could also use a data centre that could host it for them if they don't have a facility themselves. Data backups need to be tested to make sure they work. There are often changes to systems and technology being used, so there is a chance that some of the backups might not work if there have been changes. Regular backups are important for that reason. There is also that there was a problem during the backup that those operating it were unaware of and some data may have been lost or the incorrect data was backed up. So testing is important to find any problems like that.

How can I make free and secure backups of my data?

Well, I would recommend using software from Acronis to make secure backups of data because they offer a variety of services. They also offer their products and services for an incredibly reasonable price.

Why should backups be stored off-site and periodically tested?

The reason why some business organization kept their backup database because this is part of their disaster recovery plan for their own business purpose and in order to make sure there is database available when there is an disaster happened and to ensure their business will be run in a period or time.

What is the benefit of performing buckups?

Data Backups are either done on a regular basis or your data will be lost. Any person who has had a computer stop working on them suddenly - crash - will know from there own experience what a disaster it is. Those who have used desktop computers say there are 3 things you need to know about data storage - backup, backup, backup, backup. The more experience you have with computers the more backups you will make and the more places you will find to hold the backups in case something goes wrong with the data you have.

Where can I buy a data recovery service?

Losing important computer data due to a lightening strike can be a difficult experience, made worse without the proper software. Visit http://www.paragon-software.com/backup_restore.htm and browse the excellent options. One can make routine backups before the data loss even occurs, or purchase software that recovers lost data after the fact.

Are recovery programs helpful when restoring computers?

Recovery programs are helpful when restoring computer because they help salvage data. They use data taken as backups by the computer and make it useable again.

Why is it important for the firm to make backups of the data that you use regularly?

It can be used to restore data to the system in the event the data in the system are accidently lost or destroyed

Compare and contrast quantitative and qualitative Explain how both types of information are important to biological studies?

Quantitative data may be used to make a graph or table. Qualitative is easier to explain with numbers or a written description.

Is a data file needed to make a bar graph Explain?

Yes because you need the data on the right and across the bottom to make the graph

How important do you think making backups is?

Making backups is a very important task that we should make regularly because unexpected things can happen such as hard disk crashes, unintentional file deletions. Sometimes failures can even happen for unexplainable reasons. Making a backup to a removable drive or use online storage is very important.

When should files be archived and how can they be archived on a computer?

Files should be archived as often as possible. Backup programs (of which there are many to choose from) are used to create archives. Backups can be made to a variety of storage mediums including removable drives and optical discs (CD, DVD or BluRay). Removable drives are the best option in terms of storage capacity and speed and they allow backups to be kept off-site which provides an additional measure of security in the event of fire or flood damage, for instance. Cloud-based backups are also an option for maintaining off-site backups. If you have a lot of data, a RAID system makes sense as they can be used to create automatic backups by duplicating files across two or more discs. If one disc fails, the other will keep you up and running until the faulty disc is replaced. However, if both should fail (which can happen), you'll be glad you made an off-site backup. Indeed, it's good practice to have several levels of redundancy, combining a RAID with an on-site backup in a fire-proof safe, an off-site backup in a dedicated data storage facility and a cloud-based backup for when all else fails. How often you backup is entirely dependant upon how much you are prepared to lose should disaster strike. We've all had those occasions when we've been working on a lengthy document and suddenly the power goes out, losing an hours worth of work. While there are measures we can take to minimise the loss, it is nonetheless frustrating. But when a disk fails, an hours worth of work is the least of your worries; you might lose days, weeks, even months of work, depending on when you last made a backup. So it's vital that you make regular backups. It's also important to make system backups as well as data backups. System backups only need to be done after making a change to the system, such as when updating software or adding new programs but restoring a system from backup is many times quicker than re-installing from scratch. System backups don't need to be done as often as data backups but you should always have at least one full backup of the system and another of the data. Thereafter you can make incremental backups (recording the changes since the last backup) however full backups should be made periodically. To create an archive, you first choose which files should be part of that archive. If all your documents are in your personal folder then it's simply a matter of selecting that one folder and creating a complete backup. Keeping system files separate from your data, preferably on completely separate drives, makes it easy to create separate system and data archives, however backup programs allow you to create multiple backup configurations (or tasks) that you can easily recall. Note that every file on your system has an ARCHIVE attribute associated with it. Every time you backup a file, the ARCHIVE attribute is cleared. Every time you modify or create a file, the ARCHIVE attribute is set. This simple mechanism makes it possible to determine which files have changed since they were last backed up, thus allowing you to create incremental backups. So having selected the files you wish to backup, you simply choose a full backup or an incremental backup. Incremental backups obviously take less time to complete. A normal backup cycle requires that you make a full backup at the end of each week or at the end of each month, depending on how changeable your data is. In between these backups you will make incremental backups. However, it is important that you never overwrite the most recent backup, so always keep several volumes in rotation. For instance, if you perform weekly incremental backups with a full backup every month, it would be prudent to keep at least 3 full backups in circulation (covering the previous three months) and as many as 15 incremental backups, covering up to 5 weeks in each of those 3 months. So long as one of the three full backups works, the worst case would be losing 3 months work. This is why it is important to verify your backups as soon as you make them. It's no use making a backup if it cannot be relied upon. Backup programs normally include an option to automatically verify a backup after it is made. Above all else, if your data is vital, backup your backups with an off-site backup.
