Abstract
Embodiments for providing automated selection of optimal disk types for virtualized storage by defining a minimum number of backup samples, selecting, if the minimum number of backup samples is not met for a backup operation, a solid state drive (SSD) for a virtual machine (VM) storage for a disaster recovery operation, otherwise selecting a hard disk drive (HDD) for the VM storage. The method further defines a cold HDD threshold (CHT) value and a minimal percentage of backups (PPT) value, and obtains a cold backup count based on the CHT value. It compares a ratio of the cold backup count to an amount of backups (AB) for the disaster recovery operation to the defined PPT value, and if the ratio is greater than the PPT value, it selects the SSD rather than HDD for the VM storage.
