19 Feb Data recovery from RAID (RAID arrays), NAS, SAN, servers and databases
Data Recovery. A RAID system has many advantages that a single hard disk cannot provide simultaneously. Two or more single disks are software or hardware connected to a logical drive (RAID system) to achieve the desired characteristics of a RAID array (e.g., data security and higher speed). In addition to improving data security by increasing reliability (redundancy), RAID systems provide more storage capacity (increasing capacity) and faster data throughput (more power) over a single hard disk. However, a RAID system does not provide 100% reliable protection against data loss.
At Intratec Data Recovery, we know that RAID systems and servers are the most widely used for backup purposes and often for mission-critical operations in a business. The increasing popularity of “cloud” storage or virtualization of individual workplaces also allows many companies to resort to such solutions.
A system failure or data loss can have business-critical consequences in such cases, as the important processes and processes are impaired or even interrupted. This can cause a huge amount of economic damage. If it comes to an emergency, and your company server or the RAID system has suddenly failed, the top priority is: Keep calm and do not panic!
The danger of misconduct is that the damage only gets bigger or even disastrous. Before you destroy your data yourself through improper behavior, contact one of our data recovery experts specialized in RAID data recovery, server / VM-Ware recovery.
Apart from 24/7 service, we also offer a personal contact as well as prioritized processing of the order for all RAID and server data recovery cases. Our technicians have years of data recovery experience for all types of RAID systems, as well as NAS and SAN devices, virtual servers, tape and database servers.
In general, do not perform a rebuild as long as there is no current data backup.
Rebuilding should not be carried out especially with several faulty hard disks because there is a very high risk that this will lead to a final failure of several affected hard disks during the rebuild, or that the RAID controller does not even have the bad sectors or access errors can handle.
Do not recreate the RAID. This applies to both hardware RAIDs (controller-based RAID systems) and software RAIDs (almost all NAS systems such as QNAP, Synology, WD, LACIE, Thecus, etc.). They bring the RAID up and running again, but the data and file structures will be lost by overwriting the sectors.
Do not run the FSCK (File System Consistency Checker) program or the CHKDSK (File System / File Structure Repair Disk Repair Utility) on the RAID array. The same applies to HDD regenerator and test disk. If the RAID or a hard drive in the RAID has errors, these programs can only increase the damage by destroying the file structures or, in the worst case, the individual data carriers through permanent read / write accesses.
