Linux / Unix Recovery
Professional retrieval for Ext2/3/4, XFS, JFS, Btrfs, and ZFS file systems.
LINUX / UNIX RECOVERY
Enterprise Linux & Unix Data Retrieval
Linux and Unix systems power the world's most critical servers, cloud infrastructures, and specialized engineering workstations. While these systems are renowned for their stability, they are not immune to hardware failure, human error, or complex file system corruption. Our engineers possess deep-level knowledge of the kernel-level structures that define these environments.
LVM & RAID Reconstruction
Most Linux servers utilize Logical Volume Management (LVM) to manage storage. When LVM metadata becomes corrupted or the underlying physical volumes (PVs) fail, the entire volume group can vanish. We specialize in manual metadata reconstruction and mapping of logical extents to recover your data from complex LVM2 and mdadm RAID configurations.
Advanced File System Repair
We handle the most advanced file systems including ZFS (Z-pools), Btrfs, and XFS. Whether it's a "kernel panic" during a ZFS scrub or a Btrfs tree-log corruption, our lab uses proprietary tools to navigate Inodes, Superblocks, and B-trees to extract data that standard fsck utilities cannot reach.

Common Linux/Unix Failure Scenarios:
Superblock & Inode Table Damage
The superblock contains critical metadata about the file system. If it's corrupted, the OS cannot mount the drive. We use backup superblocks and manual hex-editing to restore the file system structure.
Accidental 'rm -rf' or Formatting
Linux file systems often use journaling. If caught quickly, we can analyze the journal logs to "undo" deletions and recover files that have been unlinked but not yet overwritten.
Failed mdadm Rebuilds
A failed rebuild can leave a RAID array in an inconsistent state. We perform low-level analysis of the parity data to reconstruct the missing blocks and restore the volume.
Critical Advice for SysAdmins:
If you encounter a "Kernel Panic" or "I/O Error" on a production server, DO NOT attempt to run fsck -y. This command can be destructive, as it may delete corrupted inodes to "fix" the file system, permanently erasing your data.
Immediately unmount the affected partition or shut down the server and contact our Linux specialists for a safe evaluation.
SPECIALIZED RECOVERY SERVICES
Linux Recovery Service
Our engineers have knowledge in all of the file systems that Linux uses including: Ext2, Ext3, XFS, UFS, ReiserFS, and more down to the inode structures, group descriptors, and super blocks. We have even performed deep forensics operations and recovered data from the virtually impossible encrypted file system known as StegFS.
If you are receiving error messages from your Linux RAID system, do not try to reconfigure the RAID. Doing so can cause complications during recovery. Physically shut the system down and call Data Recovery SOS immediately for guidance. We will work with you to help you understand the problem and get your system back up and running.
