Simply put, data recovery entails retrieving data that has been lost or data inaccessible. There are tools and software that aid in the process. Some of the causes of data loss include:

  • Deleting files accidentally
  • Viruses and damaging malware
  • Mechanical damage to the hard drive
  • Power failure
  • Computer theft
  • Spilling coffee and other water damages
  • Fire accidents and explosions

Server recovery tips

  • Accidents happen. They are not pre-planned. Data disasters are a bit peel to swallow. The first step is accepting that the damage is done. Here are a few tips to follow in case of data disaster occurs:
  • Do not restore the data to the server that lost it. Store it in a separate location.
  • For SQL and Microsoft data loss failures, do not attempt to repair the original database files or information store. Work on a different copy.
  • If the data is deleted, switch off the machine immediately. Shutting down Windows only will prevent the risk of overwritten data.
  • Make regular use of a volume defragmenter
  • If a drive makes unusual mechanical noise, turn it off and seek assistance.
  • Before making any software and hardware changes, ensure you have a valid backup plan.
  • Avoid running volume repair utilities on drives suspected to be bad.
  • For power loss situation involving a RAID array, if files appear suspicious or unmountable, or if the data is inaccessible after power restoration, avoid running volume repair utilities.

So, data loss has occurred? Do we recover or not? Making a decision on whether to recover the data or not is a difficult task. Here are a few considerations before making a move:

Backup

Did you have a backup plan in place? The importance of having a reliable backup plan cannot be underestimated. Most organizations and individuals have a backup plan. It may be stored in the backup hard drive, various locations within the organization or on the network.

Data location and reloading may be time-consuming and resource depleting. It is important to ensure that the most recent copy of the data is available and located where it can be easily accessed.

Re-creation

There is an option of recreating the data. Data re-creation takes into account two aspects:

Type of data: Understanding the type of data lost will determine if the data will be recreated. For instance, it would be impossible to recreate high volume banking transactions. It is impossible to recreate digital photos.

The amount of data: Get a clear understanding of how much data was lost will help determine how much resources and time will be needed to recreate the data. The more data lost, the more time and resources needed for the recovery process and vice versa.

Also, there may be laws and legal requirements that must be followed before companies and individuals can access their data.

Selecting a data recovery provider

Questions to ask:

  • How long have you been in the service?
  • How safe and clean are your laboratories?
  • What data recovery options do you have?
  • How reliable are their customer service and technical support staff?
