Instance Restore vs Virtual Database?

by Nov 6, 2014

Have any of you tried the InstantRestore feature of SQLSafe? Currently playing with it and looks like its pretty neat, being able to restore a database within minutes (while slowly restoring the rest in the background with a performance hit). It looks like has the same features/operations as SQL Virtual Database.

Anybody know what the difference between the two software is? It looks like they both do the same thing (in regards to instantly making a database available, just a different interface).
