Raid server data recovery

Raid recovery services for all servers and raid systems. We can recover data from failed raid systems running under any raid level and operating system, from failed server rebuilds, single or multiple drive failures, etc and in many cases we are able to recover where other fail, free diagnosis even on second opinions.

Please call us to find out more. From HP Dell IBM Lenovo Compaq Fujitsu and all other server systems running any operating system and RAID level.

Server data recovery

Stand-alone servers usually have drives built-in as part of the server. On tower servers, the RAID drive bays are either inside the box, or there are a number of bays that are accessible on the front of the server. Rack-mounted servers, like the one in the photo usually have the RAID drives mounted where the drives are easily accessible. In some cases, there may be a DAS connected containing other data drives.

We can recover from all RAID server systems, from new and old. From all hard drive types, including SCSI, SAS, SATA, SSD and almost every operating system. Windows server, Linux, UNIX, etc. RAID file systems such as NTFS, REFS, EXT, XFS, UFS, ZFS, etc. Contact us if there is any doubt.


NAS RAID data recovery

NAS RAID recovery from all NAS storage equipment. Single drives to multi-bay racked NAS enclosures. From every manufacturer and operating system. EXT, EXT2, EXT3, EXT4, XFS, ZFS, Drobo BeyondRAID and from Windows and MAC based NAS equipment.

NAS Data Recovery

NAS boxes connect using a network connection. Some have built-in Wi-Fi enabling easy connection to the device. Most of them come with built-in file-sharing, music, video and photo sharing servers that can connect to and be used on computers, mobile phones, smart TVs and most other connected equipment. Allowing you to watch videos or play music anywhere you want.


DAS RAID data recovery

RAID Recovery from DAS systems.  Direct Access Storage external enclosures containing several hard drives that are connected directly to the computer, using SAS, SCSI, eSATA. We regularly recover data from drives in DAS enclosures.

DAS Data Recovery

DAS enclosures contain a number of drives that can be configured as a RAID or JBOD on the host computer. They come in all sizes that caontain 2.5 inch SAS or 3.5 inch SAS, SCSI or SATA drives. Some of the more modern ones can also contain a number of PCIe based Solid State drives.


SAN data recovery

Storage area network or SAN systems are highly complex and require the best engineers available to recover data. Having an in-depth understanding how the data is stored is vital before recovery can even commence. We can recover data from the most sophisticated systems including EMC, Equallogic, Netapp, Stornext, Centravision and Apple XSAN.

SAN Data Recovery

Storage Area Network (SAN) drive enclosures are usually found in top-end servers. Each SAN enclosure can be combined over the fiber or iSCSI network with other enclosures to form a Cluster.

These are all connected using Fiber Channel or iSCSI switches to the host server computer where the management of the SAN is configured and maintained. There can be several SAN clusters connected to the host.


RAID Recovery Process

Our RAID recovery processes are safe and use best practices. Our imaging systems for all types of hard drive, SATA/ATA, SCSI, SAS, etc all use multi-pass imaging techniques. So when we hit a bad sector, the drive will power off, then depending on the settings, it will skip a set number of sectors or skip a specific head and then continue with the cloning process.

On the second pass, the drive is read backwards and again areas are skipped on detection of a bad sector. There there are two further passes to attempt to over read the bad sectors, each with different settings for time-out, sectors to be read, what to do when specific errors are encountered, etc.

Once the cloning process is complete, we will have the best clone that is possible to be got from the hard drive and that no recovery work is made on your drives as we can work safely with the cloned drives.

Prior to cloning or imaging all our image drives are wiped prior to being used to give absolute certainty that there is no possibly of cross contamination of data. Meaning your data is totally safe with us.

The following image describes our process from receipt of the drives to the final data copy process.

RAID Recovery Process

Raid Recovery Service Levels

Our RAID recovery service levels start from a standard service which typically takes 7 days, A priority service takes up to 5 days and an emergency service where the data is worked on 24/7 until we get your critical data. These service levels will apply to arrays of less than 12 drives, because of the time it takes to clone larger numbers of drives. For larger arrays, a timescale will be advised in our quote.
