What is the difference between a file-based snapshot and a thin-LVM snapshot in SolusIO?
In the case of a file-based image, SolusIO creates a so-called "VM state snapshot" using libvirt tools. And the VM state info is stored inside the VPS image itself.
And in the case of thinLVM, SolusIO creates a so-called "disk snapshot" using lvm tools. Another logical volume is created for storing the snapshot.
