Recover lost data from NAS, DAS and SAN storage

Storage systems such as NAS (Network Attached Storage), DAS (Direct Attached Storage) and SAN (Storage Area Network) are essential for data management in companies of all sizes. Despite the high reliability they offer, they are not immune to failure. Hardware problems, human error, data corruption and cyber attacks such as ransomware are among the main causes of data loss on these devices.

In this article, you will understand the main challenges in recovering NAS, DAS and SAN storage systems and how Digital Recovery can help you restore critical information while minimizing losses.

Read on and find out how to protect your data!

Main challenges in NAS, DAS and SAN storage systems

NAS, DAS and SAN storage systems have specific characteristics that influence both their functionality and the complexity of data recovery. Below, we present the most common challenges faced with each type of storage:

1. NAS storage

NAS storage is widely used for its flexibility and ability to centralize data on a network. It allows simultaneous access by multiple users, making it a popular choice for small and medium-sized businesses. However, its direct connection to the internet makes it more susceptible to cyber attacks such as ransomware.

Among the main problems that lead to data loss on NAS systems are:

  • Hardware failures, such as worn hard disks;
  • Accidental exclusions or overlapping data;
  • Cyber attacks, such as the DeadBolt ransomware, which exploits vulnerabilities in NAS systems.

Recovering data on NAS requires specialized tools to access the RAID system (usually configured on these devices) and decrypt files when necessary.

2. DAS storage

DAS storage connects directly to the server or computer, acting as a storage extension. Its simplicity of operation makes it an ideal option for systems that don’t need remote access.

The challenges in the DAS include:

  • Mechanical problems with hard disks or SSDs;
  • Logical faults, such as accidental deletions or formatting;
  • Electrical damage that compromises controllers or disks.

Although the DAS is not directly connected to the internet, indirect attacks, such as viruses that compromise the main device, can cause data loss. DAS recovery requires detailed knowledge of the system and the interfaces used, such as SATA or SAS.

3. SAN storage

SAN storage is designed for large companies that demand high performance and low latency. It offers simultaneous access to multiple users, making it ideal for intensive applications such as databases.

However, the SAN presents unique challenges:

  • Complex configurations that make it difficult to identify faults;
  • Hardware problems in connected controllers or servers;
  • Risk of data corruption due to logical failures or human error.

SAN recovery requires advanced technology to restore data in distributed systems interconnected by high-speed networks.

How Digital Recovery solves NAS, DAS and SAN failures

Digital Recovery specializes in recovering data from NAS, DAS and SAN systems, regardless of the complexity of the problem. Our customized solutions guarantee effective results even in scenarios considered irreversible by other companies.

Exclusive recovery technologies

With over 25 years’ experience, we use technologies such as TRACER, which enables data recovery on RAID-configured devices, correcting logical errors and restoring critical information. We also offer

  • Advanced diagnosis within 24 working hours: we quickly identify the extent of the problem;
  • Remote recovery: we execute processes remotely, reducing downtime;
  • 24/7 support: our team is available for emergencies at any time.

Secure and LGPD-compliant recovery

We guarantee the confidentiality of the data retrieved through personalized NDAs and work in compliance with the General Data Protection Act (LGPD), providing total security during the process.

Recommendations to avoid data loss in the future

In addition to recovering your data, Digital Recovery also guides companies in implementing practices to protect against future failures:

  • Make regular backups: apply the 3x2x1 rule (three copies of data, two online and one offline);
  • Update software and firmware: fix vulnerabilities in NAS, DAS and SAN devices;
  • Implement redundancies: RAID systems can reduce the impact of hardware failures;
  • Monitor your environment: proactive monitoring tools help identify potential problems before they become critical.

Data loss in NAS, DAS and SAN systems can be devastating for companies, but specialized solutions such as those offered by Digital Recovery make it possible to reverse even the most challenging scenarios. With exclusive technologies and a highly trained team, we guarantee safe and efficient data recovery, helping companies to resume operations with peace of mind.
