Logical data recovery presumes a remote recovery of the requested data from readable storage media.
In order to execute a remote logical data recovery, a storage or a storage image file should be available for data access on client's side.
|
The process of the remote data recovery consists of such steps:
|
|
Preliminary case evaluation. Upon receiving customer's request, specialists of SysDev Laboratories connect to your machine for a free preliminary case evaluation. This includes assessment of data recovery chances, rough evaluation of data recovery terms and quality of the data recovery result. This also includes a preliminary assessment of the total service scope and fee. At this stage, you get a rough estimation of the case complexity and cost of the data recovery services.
|
|
Start of the recovery. With the customer’s permission, specialists of SysDev Laboratories start data recovery. An engineer
responsible for your case performs necessary operations to isolate recoverable data, reports to the customer on the quality of the recovery result and
recovers a portion of data for demonstration purposes. If the customer is satisfied with the reported quality, he/she shall pay a half of the agreed service fee
as a non-refundable payment.
|
|
Data recovery completion. The recovery specialist from SysDev Laboratories completes the operation and saves the
client’s data to a safe place. The customer pays the remaining part of the service fee, which may be reduced and re-agreed in case if the
quality of the end recovery result is lower than expected.
|
* The customer may receive the most critical data already in the recovery process, immediately after it becomes available.
Data recovery specialists of SysDev Laboratories recommend following preliminary safety measures immediately after the data loss to avoid any unrepairability of your files.
Wrong actions at the very first steps may lead to irreversible data loss.
- Stop writing operations. If you have detected a data loss problem, please, isolate the storage from any writing operations. These include work with files, downloads, system or software updates etc.
- Make a disk image. If you notice any signs of physical defects on the storage, or simply in order to enhance storage safety, please, create a disk image file. You can create a disk image using special software by yourself or turn to computer repair services.
- Do not run system repair utilities. SysDev Laboratories does not recommend running any standard file system or RAID repair utilities (such as chkdsk, fsck etc.), especially in forced and/or repair modes.
With long experience in logical data recovery and own experimental researches in the field, SysDev Laboratories are ready to offer their assistance to companies working in
data analysis and data recovery. The area of expertise covers many aspects of lost data recovery: from data distribution analysis on complex storage media to

SysDev Laboratories offers plenty of unique tools. These include tools for file restoring in most common file systems (including SGI XFS, IBM JFS, StorNext, Xsan etc.),
universal RAID recovery tools, unique file system recovery tools for rare file systems and much more.
In order to speed up data recovery, our company can supply you with necessary software tools, both ready-made and developed from scratch, in the shortest possible time.

SysDev Laboratories grant their customers discounts from the basic prices. You can get a discount up to 50% for recovery from a RAID system
in case of a controller failure and if the data remains intact. The recovery of standard software RAID systems such as "mdadm" can be also discounted.
The cost of reconstruction of a mirrored RAID1 system is calculated as recovery from a linear storage. The cost of recovery from multi-disk RAID10 system is calculated
as RAID0 with the total number of disks as number of disks in RAID10 divided by two. The cost of nested RAID1 variants is calculated as conventional not-mirrored
RAID with the number of disks divided by two.
Depending on the data loss case, significant discount may be provided to individuals not aimed at commercial data recovery.
