Server Data Recovery for Windows Server, Linux, and Virtualized Environments (Western PA, OH, WV, NY)
in Butler, PA

A server failure is almost never a request for raw bytes; it is a request for a working environment back. The customer doesn't need a disk image, they need their accounting database attachable in SQL Server, their mail store mountable in Exchange, their file shares browsable, or their virtual machines bootable on a surviving host. We scope every server recovery around the deliverable the customer actually needs to resume operation. Where the underlying storage failed (a dead RAID controller, a degraded array, a failed boot volume) we reconstruct the storage layer first, but the engagement doesn't end there; it ends when the application or database or VM the customer depends on is verified usable, not when an image finishes copying. That distinction is the difference between a recovery and a pile of data the customer then has to hire someone else to make sense of.

Database files fail in ways a generic file-recovery pass can't fix: a SQL Server database marked SUSPECT after a power loss mid-transaction, an MDF without its matching LDF, torn pages and checksum failures, a database that won't attach because the log is missing or inconsistent. Exchange stores go into dirty-shutdown state with an EDB that needs the right combination of soft and hard recovery, or a transaction-log sequence that's broken. We recover at the database-internals level: extracting tables and data pages directly from a damaged MDF when normal attach fails, replaying or rebuilding transaction logs, repairing page-level corruption, and exporting to a clean database the customer's application can use. For Exchange we recover mailbox data from dirty-shutdown and corrupted EDB stores and export to PST or a clean store. MySQL/MariaDB (InnoDB tablespace corruption, ibdata recovery) and PostgreSQL recovery are handled at the same internals level.

Virtualized servers concentrate the risk: one failed datastore can take down every VM the host was running. We recover deleted or corrupted VMDK and VHDX files, reconstruct lost VMFS datastores after a controller failure or accidental reformat, untangle orphaned or broken snapshot chains (the delta-disk chains that break when a snapshot consolidation fails mid-operation and leave the VM unbootable), and repair virtual-disk descriptors and flat-file boundaries that were left inconsistent by the underlying storage failure. The deliverable is a set of VMDKs or VHDXs the customer's surviving or rebuilt ESXi, Hyper-V, or Proxmox host can register and power on. Where a guest's filesystem or an application inside the VM was also damaged, we recover at that level too, so the customer gets a booting VM with a working application rather than a VM that powers on to a corrupt OS.

Below the application layer sits the server OS itself, and a failed boot volume, a corrupted Active Directory database (the NTDS.dit), or a broken Linux LVM/filesystem stack each has its own recovery path. On Windows Server we recover from failed boot volumes, corrupted registries, broken bare-metal-recovery backups, and damaged NTDS.dit Active Directory databases (extracting accounts, group policy, and the directory structure where a domain controller is unrecoverable as a running system). On Linux we handle ext4 and XFS corruption, broken or partially-assembled LVM volume groups, mdadm software-RAID reassembly, and Btrfs/ZFS pool recovery. The goal across both is the same: either return the server to a bootable state or extract everything needed to rebuild it cleanly on new hardware without losing the data, the configuration, or the identity layer the rest of the network depends on.

The discipline that separates a recovery from a gamble is that we never run recovery operations against the live, failing server. Every server recovery starts by imaging the underlying storage (each RAID member, each volume, each datastore) to forensically clean working copies, and all reconstruction, database repair, and VM extraction runs against those images. The physical drives are left untouched as a fallback so that if a recovery approach doesn't pan out, we can start over from the original state rather than from whatever a failed in-place repair left behind. This is the opposite of the well-intentioned but destructive instinct to run chkdsk, a database repair-with-data-loss, or a snapshot consolidation against the live server and hope; those in-place operations frequently turn a recoverable failure into an unrecoverable one, and the imaging-first approach is what keeps every option open.

A server recovery usually happens because the customer is down right now, which means the recovery has to run alongside a plan to get them operational, not in a vacuum. We coordinate the data recovery with a parallel stand-up plan: while we recover the failed environment from images, we help the customer bring a temporary or replacement environment online (a spare host, a cloud instance, restored-from-backup systems for the parts that had clean backups) so the business isn't waiting idle for the full recovery to finish. Where the failure exposed a backup gap (the backup that turned out to be failing silently, the VM that was never in the backup job, the database backup that hadn't run in weeks), we document it and fix it as part of the rebuild so the customer comes out of the incident with a backup posture that actually works, rather than walking back into the same single point of failure that caused the outage.
