useful thing to remember about these systems: you fuck up and it’s a high likelihood literally nobody at the company can do any work because all their files are inaccessible
that’s like… $10000/hr in lost man hours alone, let alone reputation from not being able to respond to customers accurately, possibly missed SLAs or other contract obligations
unless your company is all about tech, it’s highly unlikely your IT team has the skills necessary to take on that level of responsibility
