We were looking for physical tape backups to protect against DR situations but were concerned about the fact that it would require manual intervention, with respect to the changing of tapes and sending them offsite. This is something that we could easily forget.
Luckily, I came across Starwind VTL. This product is the same as having a physical tape library without the hassle of changing tapes. The whole process is automated and we have the option of choosing between multiple cloud storage providers such as Amazon, Wasabi, Azure, etc.
It's been six months and it has been working well without any issue. The jobs are completed within 24 hours, which meets our RTO.
In regards to the cost, we ended up saving a few thousand dollars as well, due to the high cost of the physical tape library.
We are using StarWind's VTL to upload virtual tapes to Amazon and Wasabi simultaneously, in addition to having local virtual tape backups via Veeam. We did not have to purchase a new backup solution, as Starwind integrates seamlessly with Veeam.
Also, by integrating with Veeam, we are able to leverage deduplication and compression features with the virtual tapes. This allows for the uploads to finish quicker, as well. Because of this, we are able to meet our disaster recovery objectives within a 24 hour period.
We also avoided the costs of a physical tape library, as well as having to need users to change tapes and schedule offsite pickups.
