Backup Restore Faster Than Data Recovery

It is quite common even for experienced IT professionals to believe “I have a backup, so my data is safe.” Unfortunately there are many problems which can befall even the best prepared backup plans when disaster recovery is required.

When the amount of data which needs to be restored is small and easily found on the backup media or cloud service provider, there is no question that restoring the data will be faster than data recovery. If any required data was created or modified since the last backup, there will be a need for data recovery services.

Restoring the Data

On the face of it, restoring the data from tape is a simple process of selecting the files to be restored in the backup software, and then placing the indicated tapes into the drive as required. The situation is much the same when the data is backed up to a cloud service provider. However a good disaster recovery plan should highlight where any delays could occur to hold up this process.

The speed at which data can be restored from tape depends on several factors, such as the type of the media and drive being used and even the speed of the network if the backup is performed by a single server. Another key factor, often forgotten, is how long it takes to retrieve the tapes should they have been stored off-site, which is common practice in a disaster recovery plan.

We have discussed in a news article about how suitable cloud storage is for backing up large quantities of data. This method of backing data up is becoming ever more popular, but the speed of you internet connection could lead to serious issues when it comes to restoring your data before it starts to have an impact on the running of your business.

Another often forgotten aspect which is critical, following the failure of a computer system, is how long it will take have a replacement system set up to restore the data onto. This may include purchasing and installation of equipment, or installing an operating system, all of which needs to be factored into the overall restoration timescale.

Emergency Data Recovery

In the event of a disaster it is important to assess all options available, and the timescales involved for each. The more data which is involved, the more likely an emergency data recovery will be able to restore your important files in a shorter time period. This is of particular relevance for data backed up to a cloud service provider.

Even from a tape backup, this may be the case with or without complications. It is therefore important to determine the overall restoration timescale, and prepare the failed system for data recovery in the event it’s required, to avoid any delays. The preparation of a new system is not a factor in the timescale for data recovery, as this can be undertaken independently.
