Data Recovery after system crash using HP-UX based UNIX server

HTML clipboard

The servers like file servers, application servers, database servers, mail servers, domain controllers, Web Servers and NAS (Network Attached Storage) devices create the backbone of modern corporate record storage. Such server setups generally use multiple hard drives configured together in disk arrays. Due to continual operation and large volume of user requests, such hard drives may physically or logically fail and cause serious data loss. There are various NOS (Network Operating System) that maintain all the data and information for such network environments. For instance, in HP-UX UNIX, such issues can be taken care of by performing HP UNIX Data Recovery.

For UNIX server operating systems like HP-UX, the common reasons behind data loss are as follows:

1.) Erroneous or missing server registry configuration: The registry is a database of configuration settings. If you face any issues with the registry, your server may crash and the critical data stored in it will become unusable.

2.) Intermittent drive failure due to system software issues: The server configuration can get severely impacted due to such problems. The system software (here HP-UX UNIX operating system) may get corrupt due to various issues like incorrect shut down, virus infection, vandalism etc.

3.) Failure of multiple drives: In setups like RAID (Redundant Array of Independent/Inexpensive Disks) arrays, the hard drives undergo continual stress due to large volume of data transfer. Thus, there is always a probability of software or hardware level crash due to such constantly utilized storage setups as RAID or JBOD (Just a Bunch Of Disks) in UNIX.

4.) User errors as accidental deletion: At times, the users at the client-end erroneously delete certain data as database records, personal folder files, shared resources and more. To salvage such critical files from the hard drive, you need to opt for HP UNIX Data Recovery.

Such issues can easily be resolved by implementing efficient recovery tools. In other words, you need to take certain minimum precautions as to avoid any disk overwrite operations or opening the hard disk. In such situations, we need to narrow down to the nature of system failure. A system (as here a HP-UX UNIX based server) failure can fail due to software based corruption or hardware based malfunction. You can extract all your lost data with the help of quality data recovery software and efficient data recovery services. The hard drive can be connected as a slave or using an interface adapter device (as a chassis or a cable). The unix data recovery software should be installed on a working system/hard drive to scan the affected hard drive. Generally, these software provide the preview feature, so that you can preview the lost files detected by the recovery software and recover them as per your preference. After you are done with the selection, you can simply save them to a safe location as a hard drive (you should en
sure that you do not save the recovered files to the affected hard drive, not even to a different and healthy partition of it). Then, you can go for a clean operating system (HP-UX) reinstall. You will need to configure your server from the beginning and it is highly recommended that you opt for automated data backup on some different storage media. The recovery service a step ahead of the recovery software. The recovery experts carry out optimum recovery of critical server data through advanced component level steps like opening the hard drive and repairing the malfunctioned parts. They provide solutions for extracting all critical server data post both physical and logical failures.

Stellar Phoenix HP UNIX Data Recovery is efficient hp unix data recovery tool. The software supports recovery from JFS 3.0, 3.1 and 3.3 file systems. This Data Recovery HP UNIX tool supports recovery from SCSI, SATA, EIDE and IDE hard drives. Stellar also provides state-of-the-art data recovery services under sterile lab environment of Class-100 Clean Rooms. The recovery services cover PC, Mac, Server, RAID, SAN and NAS storage media as hard drive, SSDs (Solid State Drives) along with USB flash drives.
