Recover files SAN (Storage Area Network)

The recovery of data lost on SAN Storages is possible with our solutions.

The SAN system is a step up from its siblings, NAS and DAS. SAN is an enterprise system designed to provide high performance, low latency storage by combining storage servers with high-speed interconnects.

The low latency is of paramount importance, especially for companies that have a high flow of access to information, by several people at the same time, in demanding applications.

The main objective of SAN is to allow simultaneous access and sharing of the same file, that is, several users can access the same file and make changes simultaneously.

The SAN is more complex and more expensive than the NAS, it is generally used by large companies that have an internal IT team.

Even if there is a whole IT team and settings to prevent any kind of failure affecting the stored files, data loss in SAN devices is not impossible, on the contrary, they can be recurrent.

From a hardware malfunction, a configuration error, logical failures and even cyber attacks, all these cases can lead to a disastrous loss of data, leaving the entire system unusable, paralyzing the operation of a company, which consequently can generate huge losses.

Up-to-date backups are a great response to data loss, but there are cases where there was an error and the backup is not available or is outdated. In these cases a specialist SAN data recovery company will need to be called in. Digital Recovery has been handling highly complex data loss cases for over 25 years.

Why Digital Recovery?

Digital Recovery is a company specializing in data recovery on personal and corporate devices. Over the years, we have developed our own technologies, which allow us to recover data from virtually any storage device, from HDDs and SSDs to complex RAID systems of any level, Storages (NAS, DAS, SAN), large servers, databases, virtual machines, among others.

Our main tool is called the Tracer, and with its help we achieve high percentages of successful cases in the most complex data loss scenarios.

Even if the data has been encrypted after a ransomware attack and is completely unavailable, even in this scenario our solutions can be applied.

We have the best professionals in the area, in emergency cases our laboratories operate with 24×7 availability, so that the recovery is done as quickly as possible.

Answers from our experts

What are the main problems causing data loss on SAN Storages?

  • Logical Problems – This type of problem includes deletion of files, deletion and formatting of partitions and overwriting of data. Depending on the extent of the problem, the user can try to reverse the disaster by backing up the system. However, great care must be taken not to create an even bigger problem by trying to solve the problem. It is quite common to receive cases where the good intention to solve the problem, but allied to the little experience of users and technicians in IT resulted in an even bigger problem and unfortunately without possibility of solution, that is, the definitive loss of data. Besides logical problems in storage disks, controllers can also lose their configurations and compromise access to storage data.
  • Hardware Problems – All parts of a server are pieces that have been through careful engineering design, resiliency testing, and exhaustion testing. This means that your customers’ information is on a device with a much higher level of security than ordinary devices. However, after years of working without a single problem happening, one or another part of the server may stop working. The most common problems are hard disk wear and tear and problems related to RAID controllers. Problems may also occur in other parts of the server such as motherboards, connectors and interface devices. However, these devices do not compromise data integrity and can be replaced to re-establish data access without major problems.
  • Electronic Circuit Crashes – Electrical crashes, although rare in a data center environment, can also occur. If this happens to only one disk (system with RAID 5 and RAID 10) the RAID system will work degraded but without data loss. To solve the problem just replace the disk that stopped by a new disk so that the system itself triggers the rebuild process (reconstruction of information) and after this process the array will return to normality. If two or more disks are damaged it is very likely that it will be necessary to resort to the system backup. If it is not up to date or out of date, you should consider consulting a company specialised in data recovery. If the storage is configured with a RAID 6 arrangement, even if two disks have a problem, the system will still have access to the data and will continue to function in a degraded way until both disks are replaced. If by chance the disks are swapped and a third disk goes bad before the rebuild process of the first two failed disks is complete, the storage will inevitably stop working.
  • Ransomware attacks – In recent years cyber attacks have become quite common. According to a report by global cybersecurity solutions company Check Point, 97% of businesses worldwide suffered at least one malware offensive in 2020. The most active malware in recent years is ransomware, hacker groups have specialised in encrypting victims’ data by charging high amounts to have the data restored.

What are the benefits of SAN?

We can summarise the benefits in:

  • Accessing data quickly and with low latency;
  • Prevent stress in the local network;
  • Providing simultaneous access to applications that require this sharing (Ex: applications for video production).

What are the differences between SAN and NAS?

If we look up, the two have the same goal, manage and store data from a network. But although they seem to do the same thing, the SAN is designed for corporate use, while the NAS can be used in homes and small businesses.

SAN is more expensive compared to NAS and requires specialised administration. SAN works as a local hard drive, while NAS works as a network attached drive.

These are just a few differences, the two have many other features that differentiate them.

What you need to know

No, although they look similar they have small differences that disassociate them.

The Storage was developed for data storage, while the server, in addition to data storage, provides data processing, being possible even the installation of operating systems. Besides the tolerance to storage failures being much higher than the tolerance to server failures.

It is worth remembering that with the help of a RAID system the two can work together.

The NAS (Network Attached Storage) is one of the configurations of a Storage, they are: NAS, DAS and SAN. But the NAS is the most used configuration.

NAS system enables data access by all network users with proper permissions. NAS systems are flexible and can be expanded as needed.

One of its benefits is that it is possible to have a local private cloud, reducing costs and facilitating local control.

No, not at all. Many users use systems without backing up their data. It is important to note that as fault tolerant as equipment is, it is not immune. So it is important to keep one or more copies of the data in different locations, as it is a good practice against data loss.

We recommend applying the 3x2x1 backup system (three copies, two online, one offline).

Yes, in the vast majority of cases, depending on the cause of the data loss. If the data loss was due to physical damage to the hard disks it will be necessary to send the same.

Remote recovery requires only a laptop that is exclusively for the process, connected to the Storage and with a good internet connection. Remote recovery is perfect for companies that need to recover data quickly.
