Recover DAS (Direct Attached Storage)
DAS is designed to be connected directly to a server or computer as a storage extension, unlike NAS and SAN systems that 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. 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 failure, logical failure, and human error.
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 from DAS devices.
We provide all of our clients with a confidentiality agreement (NDA) developed by our specialists, which guarantees that no information about the recovery process will be disclosed.
Our solutions can be executed remotely anywhere in the world in a fast and secure way. During the entire process, the client will be accompanied by one of our specialists who will be able to clarify any questions that may arise during the recovery process.
We realize 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 customers say about us
"We had a serious issue following a NAS server power outage in Raid 5. I immediately contacted DIGITAL RECOVERY. After a few days of hard work the issue was resolved."
"One of our RAID servers had stopped. After several attempts without fixing the problem we found DIGITAL RECOVERY and 5 hours later, at 4:00 am, the data was recovered."
"We referred DIGITAL RECOVERY in a special case (data loss) in a storage RAID 5. Digital Recovery recovered 32 million files and the customer was extremely satisfied."
"Without any doubts the best data recovery company. Digital Recovery contact details will always be saved on my cell phone, as I will inevitably need it again."
"The quality of the service is excellent. The attention given to the service is gratifying and the feedbacks that are given leave us calm, knowing that we can trust in 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 deleting files, deleting and formatting partitions, and overwriting data. Depending on the extent of the problem, you can try to reverse the disaster by backing up your system yourself. But one has to be very careful 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 IT technicians resulted in an even bigger problem and unfortunately without possibility of solution, that is, the definitive loss of data. Besides logical problems in the storage disks, the controllers can also lose their configurations and compromise access to the storage data.
- Hardware problems – All the parts of a server are parts 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 when compared to standard 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 problems related to RAID controllers. Problems can also occur in other parts of the server such as motherboards, connectors, and interface devices. However, these devices do not compromise the integrity of the data. If they are replaced, data access can be re-established without major problems.
- Electronic Circuit Crashes – Electrical crashes although rare in a data center environment can also happen. If this happens to only one disk (system with RAID 5 and RAID 10) the RAID system will function in a degraded fashion 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 the system’s backup will be necessary. If it is not up to date or out of date, you should consider consulting a company that specializes 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 fashion 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 crashed disks is complete, inevitably the storage will 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 specialized 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 have 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 execute mass attacks, one ransomware extension stood out in these attacks, was DeadBolt.
The companies that develop 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 separate them.
The Storage was developed for data storage, while the server, besides storing data, provides data processing, and it is even possible to install operating systems. Besides the fact that the fault tolerance of a storage is much higher than the fault tolerance of a server.
It is worth remembering that with the help of a RAID system the two can work together.
What is NAS?
NAS (Network Attached Storage) is one of the configurations of a Storage, they are: NAS, DAS and SAN. But NAS is the most used configuration.
The NAS system enables data access by all network users with proper permissions. NAS systems are flexible and can be expanded as needed.
One of their benefits is that it is possible to have a local private cloud, lowering 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 the equipment may be, it is not immune. So it is important to keep one or more copies of your 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 what the cause of the data loss was. If the data loss was due to physical damage to the hard disks, it will be necessary to send the hard disks.
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.
