Introduction

VMFS Recovery software is a powerful tool designed to recover data stored on VMware disks created with VMFS file systems. With its robust recovery procedures, VMFS Recovery is an indispensable tool for anyone using virtual machines and disks, including VMware, VirtualPC, VirtualBox, Parallels, EnCase, ProDiscover disk images, and more. In this article, we will delve into the world of VMFS Recovery, exploring its features, benefits, and capabilities.

Understanding VMFS Failure

VMFS failure can occur due to various reasons, including damaged blocks and corrupted RAID arrays. A RAID array failure can be particularly devastating, especially when it affects a large cluster of virtual PCs controlled by VMware ESX Server. In such cases, the RAID controller or array may fail, leading to data loss and system downtime. VMFS Recovery is designed to tackle such complex scenarios, providing a corrupted RAID array reconstruction even when the dedicated RAID controller is damaged or inaccessible.

VMFS Recovery Features and Benefits

VMFS Recovery offers a range of features and benefits that make it an essential tool for virtual machine administrators. Some of its key features include:

Support for VMFS partitions up to 64 TB: VMFS Recovery can handle large VMFS partitions, making it an ideal solution for organizations with extensive virtual infrastructure.
Support for files up to 2 TB: With the ability to recover files up to 2 TB, VMFS Recovery can handle even the largest virtual machine files.
VMFS5 drive support: VMFS Recovery supports VMFS5 drives with more than 100,000 files, making it a reliable solution for large-scale virtual environments.
JBOD, RAID 0, 1, 1E, RAID4, RAID5, RAID5R, 0+1, and 1+0 support: VMFS Recovery can recover virtual PC images from safe and corrupted hard drives and RAID arrays, including JBOD, RAID 0, 1, 1E, RAID4, RAID5, RAID5R, 0+1, and 1+0 configurations.
Two recovery modes: VMFS Recovery offers two recovery modes: Fast mode for existing or deleted files recovery, and Full mode for complex recovery scenarios.

Recovering Virtual PC Images from ESX Servers

VMFS Recovery can recover virtual PC images from ESX servers, performing a two-stage procedure:

Damaged ESX/ESXi storage recovery: In the first stage, VMFS Recovery recovers the damaged ESX/ESXi storage, gaining access to separate virtual machines and their VDMK disks.
Recovery procedures: Once the storage is recovered, VMFS Recovery performs a number of necessary recovery procedures, successfully restoring the virtual PC images.

Conclusion

VMFS Recovery is a powerful tool designed to recover data stored on VMware disks created with VMFS file systems. With its robust recovery procedures, VMFS Recovery is an indispensable tool for anyone using virtual machines and disks. Its features and benefits, including support for large VMFS partitions, files, and RAID configurations, make it an essential solution for organizations with extensive virtual infrastructure. Whether you're dealing with damaged blocks, corrupted RAID arrays, or complex recovery scenarios, VMFS Recovery is the perfect tool to have in your arsenal.

System Requirements

To run VMFS Recovery, you'll need:

Windows operating system: VMFS Recovery is compatible with Windows operating systems, including Windows 10, Windows 8, and Windows 7.
