Roll back to previous revision

[llarsen]

Is there a way to rollback a version of a VI to a previous version if, for example, a bug is found and the previous version of the VI is wanted?

[Pnt]

No.

Always keep backup !

Only if you have a source control system in place.

It's trivial if you are using a source code control program. Look into the open source program called Subversion.
