Entire VM or Volume
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).

Although DataCore SANsymphony uses block-storage, the platform is capable of attaining per VM-granularity if desired.

In Microsoft Hyper-V environments, when a VM with vdisks is created through SCVMM, DataCore can be instructed to automatically carve out a Virtual Disk (=storage volume) for every individual vdisk. This way there is a 1-to-1 alignment from end-to-end and snapshots can be created on the VM-level. The per-VM functionality is realized by installing the DataCore Storage Management Provider in SCVMM.

Because of the per-host storage limitations in VMware vSphere environments, VVols is leveraged to provide per VM-granularity. DataCore has VVols certification for VMware vSphere 6.0-6.0U3.

When configuring the virtual environment as described above, effectively VM-restores are possible.

For file-level restores a Virtual Disk snapshot needs to be mounted so the file can be read from the mount. Many simultaneous rollback points for the same Virtual Disk can coexist at the same time, allowing end-users to compare data states. Mounting and changing rollback points does not alter the original Virtual Disk.
