Special tool for Ext2-Ext4 recovery

Recover lost or deleted files from all types of storages formatted with Linux native Ext2, Ext3 and Ext4 file systems.

Fast evaluation of file system state

Pre-start basic file system diagnostics assesses general file system condition that helps determine data recovery direction.

Recovery from replaced file systems

Accurate detection of current and previous file systems after format and targeting recovery process at certain file system state.

Advanced all-at-once recovery

Provides for selection of necessary files and building file system tree similar to the original one on the target storage.

Functional extensions

Extend software operations with a set of optional external modules (plugins).

Overview

Raise Data Recovery is a group of software applications each specially designed for certain file system type as a cost-efficient data recovery solution.

Raise Data Recovery for Ext2-Ext4 can only access and recover data from modern Linux Ext2, Ext3 and Ext4 file system. Recognition of other file systems is implemented for informational puposes only.

Ext2 file system partially wipes information about the deleted file, and particularly file name reference, making recovery of real file names almost impossible. Journaled Ext3/Ext4 file systems perform deletion via the journal. Data recovery results from Ext3/Ext4 systems depend greatly on the journal size and the time the system worked after file deletion. Raise Data Recovery for Ext2-Ext4 substantially increases chances to get data recovery result as high as maximally practicable with Ext2, Ext3 and Ext4 file systems.

The software work applying the same powerful mechanisms as UFS Explorer Standard Recovery software that enable efficient recovery of accidentally deleted data and data lost due to logical file system damages after formatting hard disk, hardware malfunctions or software failures, virus attacks, power outages etc. With Raise Data Recovery you can recover data from your PC, USB flash drive, memory card of your photo/video camera, external hard drive as well as from disk images and virtual machines formatted with such file system. For enhanced capabilities the software were supplemented with plug-ins for reconstruction and further recovery from complex RAID-systems as well.

Despite restrictions that limit data recovery to one file system, the software recognizes other file systems as well - Windows (NTFS, FAT); Apple Mac OS (HFS+); Linux (Ext2, Ext3, Ext4 , Reiser, XFS, JFS (JFS2) and FreeBSD (UFS/UFS2). Raise Data Recovery will detect file system type and find lost and deleted data that allows you to define file system type and select Raise Data Recovery software for your file system.

Working with Raise Data Recovery you can be absolutely sure of complete safety of your data. The software work in a safe read-only mode and don't alter original information. Besides, you don't need any prior technical skills for work with these programs. User-friendly interface and ease-of-use make them a perfect solution even for non-experienced users.

Reasonable price of the software focused on your file system type will save your money and fast-working powerful software mechanisms will save your time.


Key features

Particular specialization on Ext2-Ext4 file system recovery

The software is adopted to efficiently search for lost Ext2-Ext4 file systems created with all latest versions of Linux OS and recover lost and deleted files from them.

Immediate data access for consistent file systems

The software allows to access data on all the supported file systems, including file systems stored on disk images, virtual disk, RAID storages etc. without the need of prior scan.

Support of disk images and virtual disks

The software allows to open disk images and virtual disks produced by virtual machines of leading virtualization software vendors (including VMware Player, VMware Workstation, Microsoft Virtual PC, Microsoft Hyper-V, Parallels Desktop etc.). This application operates virtual disks and disk image files exactly as if they were physical disks and allows to access or recover lost data from disk images and virtual disks.

Optional RAID recovery

With optional module - RAID Access Plugin - RAID Builder - the software supports virtual reconstruction of RAID system after failure of controller or RAID metadata. The program virtually builds RAID and reads its files and folders as if it was physical RAID storage. The software easily handles both simple RAID configurations (such as stripe set - RAID level 0, Span, Mirror - RAID level 1) and complex RAID such as RAID 5 and RAID 6. RAID-on-RAID feature allows to build RAID configurations of high complexity such as RAID 50, RAID 60 etc. Optional support of Runtime Software Virtual Image Files with RAID Access Plugin - VIM Import allows to set up custom RAID configuration with different data distribution algorithms.

Comprehensive files recovery

The set of tools implemented in the software provides solutions for most practical data loss cases. Depending on situation the software either simply reads or conducts deep analysis of file system metadata to find lost files. Even if the metadata is lost permanently, this program can guess file allocation basing on file system specifics, other files allocations and file content analysis to produce maximally successful data recovery result even in severe data loss cases.
