Data Backup and Retrieval in the Modern World

Introduction:

With the advancement in technology, no doubt, the problem of data backup had been resolved up to a great extent but the problem of fast data retrieval still existed until one day, virtual tape libraries were introduced. A virtual tape library is a collection of hard disk drives to provide a huge amount of storage for backing up and archiving important data. The main problem with ordinary VTLs was that they were very costly and not every company could afford them especially, the startups. To resolve this issue, StarWind has introduced StarWind Virtual Tape Library, which eliminates the need of purchasing costly backup devices.

Working of StarWind Virtual Tape Library:

StarWind virtual tape library appears as a regular tape to the backup software and the data is stored on it sequentially. However, at the time of retrieval, unlike the magnetic tapes, the data is read very quickly since the actual storage medium is not a tape rather it is a hard disk, which spins much faster than a regular tape. Furthermore, this stored data can also be replicated to cloud storage to avoid single point of failure. The detailed working steps of StarWind VTL are shown below:

  1. Primary Data -> StarWind VTL
  2. StarWind VTL-> Object Storage
  3. StarWind VTL-> Public Cloud
  4. Cloud # 1-> Cloud # 2
