What is Backup and Recovery in Computer?

What is Backup and Recovery?

The process of creating and preserving copies of data that can be used to protect organizations against data loss is defined in backup and recovery. Often, this is referred to as operational recovery. Usually, Recovery from a backup means restoring the data to the information to original location, or to an alternate location where it can be used instead of the data lost or damaged.

To safeguard against the risk of data loss due to primary hardware or software malfunction, a proper backup copy is stored in a separate device or medium, such as tape, from the primary data.

Why Backup and Recovery is important?

The aim of the backup is to establish a copy of data which, in the event of a primary data failure, can be recovered. Primary data failures can be the result of hardware or software failure, data manipulation, or a human-caused incident, such as a malicious attack (malware or virus), or unintentional data deletion, can result in primary data failures. Backup copies enable data to be restored from an earlier point in time to assist the business recover from an accidental event.

To safeguard against primary data loss or manipulation, preserving the copy of the data on a separate medium is important. This additional medium, such as a disk storage device, cloud storage container, or tape drive, may be as simple as an optical drive or USB stick or something more significant. The alternative medium may be in the same location as the primary data or at a remote location as the primary data. The possibility of weather-related events may be justified to have copies of data at remote locations.

For best results, backup copies are prepared on a consistent, regular basis to reduce the amount of data lost between backups. The more time passes between backup copies; the potential for data loss will be more while recovering from a backup. Retaining more number of copies of data provides the insurance and flexibility to restore to a point in time remains unaffected by data corruption or malicious attacks.

Why you should back up your files?

In today’s fast-paced world, backing up your files is of the utmost importance. Typically music, movies, films, data files, projects, and photos are all stored in one place – your computer. Laptops and desktops have decreased in cost, and the amount of storage inside them has increased greatly over the last few years. Unfortunately having all of your data in only one place is dangerous.

Computer loss, theft, natural disaster, and accidental deletion, are just some of the ways that you can lose the data you’ve spent so long creating and accumulating. The only way to prepare for the unexpected is to have a good backup strategy in place. There are many different ways to back up your computers, and using multiple forms of backup will minimize the risk of ever losing your valuable files.

What is a Computer Backup?

The simplest definition of a computer backup is an exact copy. In the case of computer files, we are referring to copies of the original files that you have on your laptop, desktop, or external drive. Creating a backup of original content means having that data saved in two places, but it’s also important to make sure that those two places aren’t on the same type of device. For example, if you have 3 copies of a working document on your computer, if your computer crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy!

Can I use thumb drives for backup?

Off course yes! In most cases, a simple thumb drive, also known as a flash drive is the first way most people save their data. Transportation is easy for thumb drives as it works with most computers, and is relatively small. That makes them a great way in order to save small amounts of data such as presentations or working documents. It’s also easy to give them to others, making them efficient for collaborative projects.

The downside to thumb drives is that they are usually very small and often are not very dense. This makes them problematic for a few reasons. If your thumb drive is small it’s easy to lose. If you lose your thumb drive, then you’re no longer backed up. Not having a lot of storage density is also problematic, as typically a thumb drive will be unable to hold all of the data that is on your computer. For those entire reasons, thumb drives are not an appropriate solution for backing up your PC.

How to backup Windows?

One small accident, a virus, or hard drive failure can destroy all the important stuff you care most about on your computer.

Although there are many good backup programs you can install to protect your files, Windows already has easy-to-use, built-in tools to automatically save copies of your data to an external hard drive or a shared network location. Here’s how to set it up.

The steps below will offer local backup for your data, which is great for having immediate access to your files in case your hard drive crashes or you accidentally overwrite a file but remember that you’ll also need offsite (e.g., online) backup.

Also, you’ll want more than one type of backup because all storage media, like external hard drives, are likely to die at some point.

Remember the 3-2-1 Rule of Backups:

3: Have 3 copies of your important files

2: Use 2 different types of media to back up the files

1: Store 1 copy offsite

The 3-2-1 backup rule is a best practice because it ensures that you’ll have a copy of your data no matter what happens. Multiple copies prevent you from losing the only copy of your data. Multiple locations ensure that there is no single point of failure and that your data is safe from disasters such as fires and floods.
