Data is the lifeblood of any businesses. That is why its loss can be comparable to the loss of vital organs. In order not to bring the situation to a critical state, backup is mandatory. The 3-2-1 backup strategy is most effective and based on making three copies of your data, two of which are stored on different media, and one is located offsite. In terms of keeping data off-site, backups can be stored on tapes, which today are the cheapest and most reliable carrier. But infrastructures that are completely focused on tape devices are expensive and do not provide decent performance. That is why virtual tape library with a public cloud storage tier may be a good alternative. StarWind offers StarWind Virtual Tape Library (VTL) – a solution allowing to make backup processes faster and more cost-efficient. So, why does the sequence of these numbers, 3-2-1, have magical power for your peace of mind and how does StarWind VTL fit in well with this backup plan?
