Server Data Recovery for Windows Server, Linux, and Virtualized Environments (Western PA, OH, WV, NY)
Recovery of the actual workload (bootable VMs, attachable SQL/Exchange databases, mounted file shares) from failed Windows Server, Linux, VMware, and Hyper-V environments; we recover what gets you back into operation, not a raw image you then have to figure out how to use.
When a server fails, the customer is not asking for raw bytes back; they are asking for a working environment back. The accounting database needs to be attachable in SQL Server, the mail store needs to mount in Exchange, the file shares need to be browsable, and the virtual machines need to boot on a surviving host. A raw disk image is not a recovery if the customer then has to hire someone else to turn it into a usable system. That difference, recovering the workload rather than the storage, is what server data recovery is actually about, and it is what we scope every engagement around.
MCR Business Tech Solutions recovers server data for businesses across Western Pennsylvania, eastern Ohio, the West Virginia panhandle, and western New York. We work failed Windows Server (2012 R2 through 2025), Linux (ext4, XFS, LVM, mdadm software RAID, Btrfs, ZFS), and virtualization platforms (VMware ESXi/vSphere, Microsoft Hyper-V, Proxmox). At the database layer we recover SQL Server (suspect databases, MDF without a matching LDF, torn pages), Exchange (dirty-shutdown EDB stores), and MySQL/MariaDB and PostgreSQL. At the virtualization layer we recover deleted or corrupted VMDK/VHDX files, lost VMFS datastores, and broken snapshot chains. Below both, we handle boot-volume, Active Directory, and bare-metal recovery.
Every server recovery starts by imaging the underlying storage to forensically clean working copies, and all reconstruction, database repair, and VM extraction runs against those copies. The physical drives stay untouched as a fallback, so that if one recovery approach doesn't pan out, we start over from the original state rather than from whatever a failed in-place repair left behind. This is the opposite of the instinct to run chkdsk, a data-loss database repair, or a snapshot consolidation against the live server and hope; those in-place operations routinely turn a recoverable failure into an unrecoverable one, and imaging first is what keeps every option open.
Because a server recovery almost always happens while the customer is down right now, recovery and getting operational run as two parallel tracks rather than a sequence. We help stand up a temporary or replacement environment for the parts of the business that can come back (a spare host, a cloud instance, systems that did have clean backups) while we recover the failed environment from images in parallel. And where the failure exposed a backup gap, the job that was failing silently, the VM never added to the backup set, we document it and fix it as part of the rebuild so the customer doesn't walk back into the same single point of failure.
What's included
Recovering the Workload, Not Just the Disk
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.
SQL Server, Exchange, MySQL, and PostgreSQL Database Recovery
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.
VMware, Hyper-V, and Proxmox Virtual-Machine Recovery
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.
Windows Server, Linux, and Active Directory Recovery
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.
Image First, Work From the Copy, Never Risk the Original
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.
Coordinated With Your Recovery So You're Not Down Twice
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.
Why businesses choose MCR
We Recover the Workload, Not Just the Disk
The deliverable is an attachable database, a bootable VM, a mounted file share, or a restored Active Directory, not a raw image you then have to make sense of. We reconstruct the storage layer when it failed, but the engagement ends when the application or database or VM you depend on is verified usable, not when an image finishes copying.
Database-Internals Recovery for SQL Server, Exchange, and More
SUSPECT SQL databases, an MDF without its LDF, torn pages, dirty-shutdown Exchange EDB stores, InnoDB tablespace corruption: we recover at the database-internals level, extracting tables directly from a damaged MDF when normal attach fails, replaying or rebuilding logs, and exporting to a clean database your application can actually use.
Image First, Work From the Copy, Never Risk the Original
We never run recovery operations against the live, failing server. Each RAID member, volume, and datastore is imaged to a forensically clean copy first, and all work runs against the copies, leaving the physical drives untouched as a fallback. It's the discipline that keeps every option open instead of betting the only copy on an in-place repair.
Coordinated So You're Not Down Twice
Recovery runs alongside a parallel stand-up plan so the business isn't waiting idle for the full recovery to finish, and any backup gap the failure exposed gets documented and fixed as part of the rebuild, so you come out with a backup posture that actually works rather than the same single point of failure that caused the outage.
Getting started
Triage, Image, and Scope the Deliverable
Diagnose where the failure actually sits (storage, OS, database, or virtualization layer) and image the underlying storage to forensically clean copies before touching anything. Confirm at intake what the customer needs back into operation first (which database, which VMs, which shares) so the engagement targets the critical workloads, and identify what can be stood up from any surviving clean backup in parallel.
Reconstruct and Recover the Workload
Reconstruct the storage layer if it failed (offline array rebuild independent of a dead controller, LVM/mdadm reassembly, VMFS datastore recovery), then recover the workload on top: attachable SQL/Exchange/MySQL databases via internals-level repair, bootable VMs from recovered VMDK/VHDX files and untangled snapshot chains, restored file shares and Active Directory. All work runs against the images, never the originals.
Verify, Return to Operation, and Close the Backup Gap
Verify the recovered databases attach, the VMs boot to a working OS, and the file shares are intact before declaring the recovery complete. Help bring the customer back to full operation on surviving or replacement hardware, and document and fix the backup gap the failure exposed so the rebuilt environment has a backup posture that genuinely protects against the next failure.
Frequently asked questions
Our SQL Server database is marked 'SUSPECT' after the server lost power, and the application won't start. Our IT person wants to run repair with EMERGENCY mode and REPAIR_ALLOW_DATA_LOSS. Should we?
Hold off on REPAIR_ALLOW_DATA_LOSS, because the name is literal: that command resolves corruption by deallocating the pages it can't fix, and the data on those pages is gone permanently once it runs. It is sometimes the right last resort, but it should be the last resort, run against a copy, after the recoverable options have been tried, not the first thing attempted against the only copy of a production database. The SUSPECT-after-power-loss pattern usually means SQL Server couldn't complete crash recovery because the transaction log is in an inconsistent state, and a large share of these are recoverable without data loss. The right sequence: (1) Don't run repair against the live database yet. (2) Copy the MDF and LDF files somewhere safe so you have an untouched original (if SQL has them locked, stop the SQL service first and copy the files). (3) Call us at 833-859-9021. We work from a copy of the MDF/LDF, attempt the non-destructive recovery paths first (emergency-mode access to export the data out cleanly, transaction-log rebuild, page-level repair of the specific corrupt pages), and only consider data-loss repair if nothing else works, against a copy, with the customer told exactly which pages would be lost first. Where the log is genuinely gone, we can often extract the tables and data directly from the MDF internals and rebuild a clean database from the extraction. Most power-loss SUSPECT databases come back with no data loss when they're handled this way instead of with an immediate REPAIR_ALLOW_DATA_LOSS.
Our VMware host had a storage failure and the datastore is gone. All our VMs were on it. Can you actually get the virtual machines back, or just the raw data?
We recover the virtual machines as bootable VMs, not just raw data, which is the whole point of a server recovery rather than a generic file recovery. The work runs in layers. First we reconstruct the underlying storage: if a RAID controller failed, we image the member drives and rebuild the array offline, independent of the dead controller (controller failures usually leave the drives intact, so the data is there even though a replacement controller can't read the old metadata). Then we recover the VMFS datastore structure and extract the VMDK files for each VM, repairing the VMDK descriptors and flat-file boundaries if the storage failure left them inconsistent, and untangling any snapshot chains that broke. The deliverable is a set of VMDKs your surviving or rebuilt ESXi host can register and power on. Where a snapshot consolidation had failed before the outage or a VM's guest OS was also damaged, we recover at that level too so the VM boots to a working OS rather than a corrupt one. We confirm at intake which VMs are the priority so the engagement targets your critical workloads first and gets them booting before working through the rest.
How is server recovery different from the RAID recovery you also offer, and which do we need?
RAID recovery and server recovery overlap but solve different layers of the problem, and most real server failures need both. RAID recovery is the storage layer: reconstructing the array itself from failed or dropped member drives, reverse-engineering the stripe size and drive order and parity rotation, and producing a readable volume. Server recovery is everything above that: taking the readable volume (whether it came from a RAID reconstruction, a single failed server drive, or a failed virtualization datastore) and recovering the actual workload on it, the SQL or Exchange database, the virtual machines, the Active Directory database, the file shares, in a form you can put back into operation. If your server's array dropped multiple drives, you need the RAID layer and then the server layer. If your array is healthy but a database is corrupt, a VM won't boot, or the OS volume failed, you need the server layer alone. You don't have to figure out which you need before calling; the intake diagnostic determines where the failure actually sits, and we quote the engagement around the layers your specific situation requires rather than charging for both by default.
Our server has been down for two days, our backup turned out to be failing silently, and our business is basically stopped. How fast can you get us operational and how does pricing work?
The down-right-now situation drives how we run the engagement: getting you operational and recovering the data are two parallel tracks, not a sequence where you wait idle for the full recovery before anything works. At intake we triage what's recoverable from any clean backup or surviving system versus what has to come from recovery, then help you stand up a temporary or replacement environment (a spare host, a cloud instance, the systems that did have clean backups) so the parts of the business that can come back do, while we recover the failed environment from forensic images in parallel. Recovery timelines depend on the failure: a corrupted database or a non-booting VM on healthy storage often turns around in 1-3 business days, while a multi-drive array failure carrying a full virtualization stack runs longer because the storage has to be reconstructed before the workload layer even starts. On pricing, we disclose the diagnostic fee at intake (typically $99-$249 depending on complexity), produce a written assessment of what's recoverable and through which path, and give a fixed engagement quote before any recovery work begins, so you authorize the cost knowing the scope. And because your backup was failing silently, we document that gap and fix it as part of the rebuild, you should not walk out of this incident back into the same single point of failure that caused it.
