How do the majority of companies, almost 80%, back up their data (incorrectly)?

We show you the most common data backup and archiving errors, and therefore challenges.

Imagine that you have a project team at your company of 20 people, and each person receives an email from the project manager with a 10MB attachment. Each person saves this file for themselves, taking up a total space of 200MB on the file server.

When deploying backups with traditional technology, especially magnetic tapes, all of the attachments saved to the file server are backed up, which means 200MB of storage space (magnetic tape) is used. The mail system also needs to be backed up, where depending on the structure and the type and version of mailing software, one or more copies of the attachment is stored, and so 10MB of data is backed up once or several times from the mailing system too.

With normal backup systems the saved data is backed up again and again on a weekly or monthly schedule (full backups every week or month) even if the stored data has not changed. Depending on how these backups are stored (for example the weekly backups for a month or the monthly backups for a year) the number of copies in the backup system or on backup media (cassettes, tapes) keeps on multiplying: for example, in the case of weekly backups stored for a month, storage space of 4 x 200MB = 800MB is required.

Quite evidently, this is NOT the most efficient system.

That said, data protection and data backups at most companies are still based on these principles and approaches, even today.


Don't make the same mistake!

Don’t make the same mistake!

We have a far better solution!

How much better would it be if an intelligent system only saved the original attachment once, and automatically avoided the superfluous additional saving of the same file: the other 19 instances would just refer to the same initial copy. What is more, the same technique is applied for any changes to the directories, and only the parts that were actually modified are saved again.

This means that instead of space amounting to 800MB, only capacity of a little over 10MB would be needed for the backup, in line with the size of the initial file, and that’s before we take any hardware compression into account. How much space would you set aside to backup this document? 800MB or roughly 10MB?

This is called deduplication technology, which helps to:

  • save massive amounts of storage space
  • reduce the amounts spent on disk storage
  • save on network bandwidth
  • and speed up the actual backups too.

This example is just one of many that shows where your company could make improvements to data storage and backups.

Top 5 challenges with data backups and archiving

Vegyük sorra a legfontosabb problémákat és kihívásokat, amelyekkel nap mint nap szembesülünk az adatmentés és archiválás területen:

Let’s take the main problems and challenges one after the other, all of which are everyday issues when it comes to backing up and archiving data:

1. The time available for backing data up (“backup window”) is getting shorter and shorter.

The time available for backups is steadily falling. It’s very likely that the IT operating team at your company also finds it increasingly difficult to save all of the necessary data before the backup window closes. The volume of data that needs backing up is growing, but the capacity and performance of the backup tools often cannot keep up, and even despite using newer generation backup tools the process itself is frequently slower.

2. Constant availability of critical systems OR proper backups of their data

Making proper backups of data is extremely important with critical systems. However, the (availability) requirements of these business-critical systems are so high that they cannot be shut down, and no declines in performance are permitted either. What technology could your enterprise use to backup these systems?

3. Increase in data quantity

Backups of virtual environments using traditional backup techniques results in an increasing volume of data, which can only be managed using modern backup systems that have been carefully planned and designed. Just think about it: backing up a virtual environment with 50 machines using traditional backup techniques (50 x 5GB) means a data volume of 250GB during each full backup.

4. Backing up and restoring critical business data

Data that is important to the company’s business must be backed up according to the set schedule and preserved as required. Depending on regulations the saved data may possibly have to be removed from the backup system, the backups themselves may have to be archived and/or removed to a remote or protected location. We have to make sure that the data can be traced and restored if need be.

5. Legal regulations

The company also has to comply with legal regulations. Storing and preserving corporate data is subject to many different laws.

One more thing: what if a disaster occurs?

The backup system is NOT a separate and isolated part of the data centre, it is integral to the entire IT infrastructure. If we prepare a disaster recovery plan for our data centre, then appropriate procedures must be created for the backup system as well. Copies of the backed up data and the backup records (catalogues) must be stored in a remote and protected location in case of a disaster.

Have a detailed scenario prepared in the event of a disaster!

Have a detailed scenario prepared in the event of a disaster!

Unfortunately, it often transpires that a backup system or a specific backup is not right when it is most needed: when data needs to be restored, or in the event of a more severe disaster.

It may turn out that the data to be restored is damaged or the data is inconsistent, restoring the data is unacceptably slow, or the restoring process after a disaster is complex and ill-conceived. It is important to have developed procedures for these cases so that we can reliably create a functional backup environment from our existing data.

It’s not only the backups that need to be quick, but also the restoration process. It is unacceptable for business processes if it takes many hours to restore an important database.

So what’s the solution? How can these challenges be addressed?

We can help!

We can help!

Our experience shows that most clients look for backup solutions that can be flexibly adapted in accordance with their requirements.

The good news is ….

These are problems that we at Areus have been confronted with many times before at our clients. We can offer effective solutions to all of the problems and challenges referred to above.


One of Areus Zrt.’s main specialties is backups and archiving:

  • At many of our clients we have dramatically reduced the time required for data backups (even 1:20) by applying deduplication technologies
  • Using special disk-based backup tools (VTL, deduplication) the time needed to restore data is reduced to a fraction of what it used to be, and virtual backup frameworks can be created in a matter of seconds for the individual servers to be backed up, which reduces the number of expensive physical hardware components required
  • The data backup solutions offered by Areus are applied widely throughout Hungarian government bodies.
  • We designed and implemented the disaster-tolerant processes of the backup system for Hungary’s leading insurance company.

Our professionals boast extensive know-how of the many backup products of most enterprise hardware and software manufacturers and so we can offer the most optimal solution for the most varied of backup situations. We carefully plan and then create the backup system that is best for you.
