Time is the enemy when a data loss occurs in cloud storage, especially in a multi-tenant environment.

To increase the success of any cloud recovery, stop writing to the affected volume and contact a data recovery professional with experience in cloud recovery immediately.


The Ontrack advantage

We have the experience and proprietary technology to recover your data from cloud services.

We have recovered data for customers with cloud service platforms at every level - from small development project cloud uses to secondary infrastructure deployments, and even nationwide smartphone data servers supporting millions of mobile phone users.

Cloud solutions for all platforms and data loss situations

We recover from all cloud platforms and any type of data loss. Here's an overview of common cloud platforms and typical data loss scenarios we can recover from.

Cloud data recovery process

A successful recovery of cloud data requires remote access through your administrator account and verification of the storage device or system and the file system that contains the requested data.

Data recovery steps Description
Stage 1

Target LUN, iSCSI* LUN identification and low level RAID verification at the storage block level.

Stage 2

Datastore volume file system indices are checked for metadata-to-data stream integrity.**

Stage 3

Guest file system and contents are verified.

Stage 4

File listing of all recoverable data is completed.


*iSCSI LUNs are reliant upon the SAN's internal file system to manage the data. Data loss within this type of logical storage may require access to the SAN's volume where the iSCSI files are stored.

**Target volumes that reside within virtual disk files are dependent upon the hypervisor's datastore file system to manage the data. Data loss at the hypervisor volume level or within the guest's virtual disk file may require additional engineering effort to complete the evaluation.

Cloud recovery solutions

Remote Data Recovery

Remote Data Recovery is the best option for cloud recovery due to the speed of the recovery process. It is the fastest way to access and recover your data. This cloud recovery is completed via a secure internet connection using proprietary tools. This method is not only fast, but cost effective as well.

In house recovery

Cloud storage providers can experience hardware failures just like any other data storage provider. If this is the cause for the data loss, an in lab or cleanroom recovery may be required, especially if the hardware has been physically damaged.


If the hardware at the cloud storage provider has failed and cannot be moved offsite due to physical size or security reasons, an onsite recovery is required. Our engineers are able to recover data onsite and, in most cases, they complete the recovery within 48 hours of their arrival.

The data recovery process

From initial consultation to ongoing support, we help businesses and consumers in any data loss situation – from simple to the most complex and catastrophic.

When business or personal data is lost, we understand that it can be a very frustrating and stressful time. That's why our data recovery process is straightforward and transparent, and we'll keep you up to date every step of the way.

Join over a half million people and businesses who have trusted Ontrack to recover their data.

We’ll collect your device and perform an evaluation, free of charge

Data recovery for single drives start from £399 + VAT, and for smartphone from £400 + VAT. The final price will be determined at the end of the evaluation, according to the complexity of the work involved and the urgency required.

To begin, start by clicking on the type of media from which you need data recovered. The evaluation time for single hard drives (HDD and SSD) is four hours*, and within 24 hours for RAID systems*. Other media, such as mobile phones do not require an evaluation to provide an accurate quotation.

*These are typical time frames and apply within normal business hours (Monday to Friday, 9am to 5pm). For an out of hours, emergency service, or if you need further assistance, please contact us on +44 (0)1372 741 999.
