Recover files DAS (Direct Attached Storage)
DAS system is designed to be connected directly to a server or computer, as a storage extension, unlike NAS and SAN systems, which are connected to a network.
DAS does not have its own operating system, so it needs the operating system of the external device to be accessed, DAS works basically like an external HDD, pen drives, etc. But with an infinitely higher capacity.
It connects via interfaces such as Small Computer System Interface (SCSI), Serial Advanced Technology Attachment (SATA), Serial-Attached SCSI (SAS), FC or Internet SCSI (iSCSI).
DAS can work with either HDDs or SSDs, it is up to the user’s choice. This system is not as susceptible to data loss from cyber attacks because it is not connected directly to the internet, but it is not impossible.
But it can suffer data loss for simpler reasons, so to speak, such as: mechanical failures, logical failures and human errors.
From the simplest to the most complex causes, Digital Recovery is able to act quickly and concisely to recover all lost data.
Why Digital Recovery?
For more than two decades, we have been in the data recovery market developing unique technologies that have allowed us to be at the forefront of data recovery on DAS devices.
We provide all our clients with a confidentiality agreement (NDA) developed by our experts, which guarantees that no information about the recovery process will be disclosed.
Our solutions can be executed remotely from anywhere in the world in a fast and secure manner. During the whole process, the client will be accompanied by one of our specialists who will be able to clarify any doubts that may arise during the recovery process.
We have taken care to develop our solutions based on current laws such a GDPR (General Data Protection Regulation).
We do how critical data loss on DAS devices can be, so we have created emergency mode recovery, when activated our labs work with a 24×7 availability so that the recovery is done as quickly as possible.

Customer experiences
What our clients say about us
"We had a serious problem after a power failure of a NAS server in Raid 5. I immediately contacted DIGITAL RECOVERY. After a few days of hard work the problem was solved."
"One of our raid servers had stopped. After several attempts without solving the problem we found DIGITAL RECOVERY and 5 hours later, at 4am, the data was recovered."
"We appointed DIGITAL RECOVERY in a special case (of data loss) in a raid 5 storage. Digital Recovery was able to recover 32 million files so our customer was extremely satisfied.”
"Without a doubt the best data recovery company in Latin America. The contact Digital Recovery will always be saved on my phone, because inevitably I will need again."
"The quality of the service is excellent. The attention given to customer service is gratifying and the feedback we receive reassures us that we can trust the work and dedication."

Answers from our experts
What are the main problems causing data loss on DAS 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.
Which Storage configuration is most susceptible to a hacker attack?
The NAS, in recent years emerged hacker groups specializing in ransomware attacks focused on NAS Storages, because they are connected directly to the internet.
Many of these attacks happened as a result of newly discovered flaws by ransomware, this gave them advantages to perform attacks en masse, an extension ransomware stood out in these attacks, was the DeadBolt.
The companies developing these devices have been releasing constant updates to fix these flaws. These updates can come too late, which leaves the company’s entire system available to be encrypted by a ransomware attack.

What you need to know
Can Storage be used as a server?
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.
What is NAS?
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.
Does a NAS replace a backup system?
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).
Is it possible to recover Storage remotely?
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 only requires 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.
