NAS / SAN / DAS & Network Storage Data Recovery

NAS, SAN Data Recovery NAS and SAN are now widely used to store large amount of data in big businesses. These devices are generally accessed thorough network connection and have taken over the traditional file serving method and Direct Attached Storage (DAS), where server was responsible for serving/storing and managing the data.

Generally SAN is referred as “Block level storage and NAS as “File level storage”.

The SAN is known as Enterprise storage, it allows remote connection over a network with disk drives, tape drives for block level I/O, and it also uses Fibre and iSCSI protocols for the transfer of data over network at faster rates.

The NAS is mostly used as general centralized data storage for users with large amounts of data. NAS is widely used due to being simpler and low cost for load-balancing and fault-tolerance of corporate data, email and web server systems. NAS comes in various options differing in interface and type of drives, it has either SATA, IDE or SCSI interface which mostly works on “NFS, SMB or CIFS”.

Expert tips!!!

Never reinitialize drives
Do not force the drives online
Never change the sequence of the Raid Drives
Do not reinstall Operating system
Do not create new partitions
Immediately switch off Raid drives upon hearing unusual sound from the Raid drive
Label all drives according to their position in Raid Array
Always seek professional help, Call Disk Doctors at 0800 043 6611

NAS/SAN/DAS Data Recovery Process:
At Free Evaluation stage, we gather valuable information about the NAS or SAN boxes, such as:

Level of RAID if any i.e. JBOD, RAID 0, RAID 1, RAID 5
Exact issue with the media
Details of any hit and trial method carried out on the media by the client.

Once we gather complete information as mentioned above, we send an evaluation report with a fixed quotation for approval. Recovery starts upon approval; there are various specialized methods of recovery which may include.

Using a clean room facility to fix the physically failed drives and getting them to work.
Creating bit by bit secure replica of the media
Identifying parity technique, using in-house developed applications.
Rebuilding the data from fragmented stripes together (applicable to RAID 5 arrays)

Most of issues are very complex besides the points mentioned below, which is tackled with other in-house developed techniques. We guarantee to recover your data or you don’t pay us anything.

Supported Data Loss Situations

Deletion or re-intialization of LUN's (Specific to SAN)
Two or more hard drives fail or go offline
Addition of incompatible hard drives to the array
Hardware / Software malfunction
Virus infection, software and operating system upgrades
Natural Disasters
Physical damage to media

Other Supported Backup Formats

Microsoft Backup
UNIX, Linux Tape Backup
Backup formats of Arcserve, Legato, HP, Veritas etc.

Data Protection & Confidentiality

Disk Doctors guarantees protection of your data throughout the data recovery process, from evaluation to handing data back to the client.

Disk Doctor Employees are selected through a rigorous process of selection and follow our strict rules and procedures for handling the client data.
Client media is cloned sector by sector onto our own lab media and all the data recovery work is carried out on the cloned media not the original media; this ensures that client’s storage media is always intact.
Upon successful recovery Disk Doctors by default keeps a copy of the data for 7days before it gets deleted automatically from our Lab Server. This helps in providing the copy of data again if some thing goes wrong during the transfer of data to client e.g. the data media gets damage or goes missing during the postal process.
Our agreement to recover the data includes the clause for protection and non disclosure of data as per legal rules and regulations. If you require separate agreement for data protection and non disclosure, we are happy to sign the agreement.
