In times when files are increasingly vulnerable to loss and theft, data backup is essential. This process involves copying files on platforms with specific storage functions, such as on media and HDs, in the cloud or servers.
Large companies, micro-enterprises, and home office workers benefit from the secure copy of information, and there are several methods to accomplish this. Continue reading and see what ways to back up data are!
The Importance Of Data Backup For Companies
You’ve probably already had the experience of losing a large volume of data, so before learning about the leading data backup solutions, see how essential file copies are. Imagine: In a sales office, meetings with essential customers on complex issues are scheduled for the next week.
Suddenly, a cyber attack on the company’s database prevents access to meeting information. And now? What time should each customer arrive? How do we know the subjects addressed for the team to prepare? Is there confidential content? In these cases, if the company does not back up data, it gets in trouble! This is just one example of how businesses should take precautions and copy data.
Backup Against Ransomware
The English word “ransomware” means “rescue of goods.” A ransomware attack happens in the following way:
1: Hackers access the company’s database. These offenders trigger applications to block access to information;
2: When the company tries to access the data, a message appears on the screen informing about the blockage;
3: To release access, hackers require payment of a specific financial amount. This blackmailing practice is common in small companies without a security team prepared to defend the data.
If daily backups are performed, this won’t be easy to happen. After all, to recover everything, you just need to use the last copy after cleaning the hard drive.
Types Of Data Backup
Now, let’s get to know the best ways to back up your business data:
Home Data Backup
It is one of the most common ways to copy data. Occurs when you copy files directly to media (DVD / CD) or external HD. In small companies without a lot of essential data, it is worthwhile to periodically back up all information at home.
Microenterprises with extensive volumes of precious data copy the most essential information in-house. The rest can be copied in other ways. A home data backup is safe from hackers because the information doesn’t go online. However, there is a particular vulnerability to robbery or theft in physical environments.
It is possible to perform Backups using servers with online storage spaces that can be used to receive backup backup copies. To do so, you need to rent a server service in the cloud (Amazon, LocaWeb, Azure, for example).
When you do this, a remote storage space will become available to receive copies of backup files.
Some cloud backup services already offer their software to perform copying tasks. Others require extra backup software purchases.
Full Data Backup
In this form of backup, all company data and files can be updated, without exception, from older content to new information. To make this copy, you must have a backup system with plenty of space and fast.
Complete data backup is an exciting option for companies looking for a method that saves old and current information. There are two ways to carry out this process: incremental or differential. Check out!
Incremental data backup: Copies files generated or updated after the last full backup. Require less memory space because storage demand is less. Data recovery is slowed down by the need to verify the last full backup before the programmer finds out where later changes took place.
Differential data backup: The more possibility to attach data, the higher the costs. Cost flexibility makes this backup option ideal for small to medium-sized businesses. The word differential means that only files different from the last full update go to the online backup. It is similar to the incremental backup in that it stores more data, needs a lot of space, and retrieves information quickly.
Recovery is fast because it references the last full data backup update. If you do a full backup on one day and a differential backup on the second and third days, the backup is still based on the first day.
