Restoring your data

Restoring data is the process of replacing damaged or lost data (in its original location) by importing a copy from a secondary location. In the case you lose data by either accidentally deleting or through some form of Malware or some other unavoidable disaster, data restoration through a backup source is a common remedy. However, this backup data needs to be updated frequently for this to be of use, as the latest version of the update will be available as a recovery copy. 

The backup method and the recovery tools used must be reliable and the backed-up data needs to be periodically checked to assure they meet recovery point objectives. Also, the applications currently running must be checked if they are compatible with data about to be restored. The security steps involved in the process of recovery must be properly adhered to. 

Data backups can be stored in different methods, each with its unique levels of convenience. 

  1. Hard Disk Drive (HDD) – Most convenient and quick location to store your data and ideal for rapidly changing data and for a quick recovery. And they are relatively secure than offsite backup locations. The tradeoff is the higher cost for running the disk units, where power and cooling methods demand significant levels running costs. 
  2. Tape backups – These offer high data storage capacity to the cost. However, the recovery time is relatively slow in comparison to the other methods available and if stored in an offsite location, will take longer. These require continuous testing and checking to see if these data are accessible.
  3. Cloud Backups – This method allows data to be backed up in an offsite facility over the network. Depending on the available speed of the network, backup and recovery may be slow. These storages can be easily expanded as required. Using a cloud service provider minimizes both workload of staff and running costs as no hardware or software handling needs to be done. 

Restore lost or damaged data. 

The recovery process entirely depends on the nature of the loss or corruption of the data. Certain software allows DIY recovery, even data that is permanently deleted. 

Other complex forms of recovery include instant recovery, replication, and CDP and as mentioned before, using hard drives.   

For mobile devices such as smartphones, tablets, and laptops, syncing software services allow other devices to handle the same data in sync. Accessing or changing can be done over multiple devices, which however does not fall into the backup category. However, most portable devices have built-in software for backing up purposes, where device data is backed up to a cloud.
