Best practice
When using "as back as", consider whether "as far back as" might provide better clarity, especially when referring to dates or historical events. For instance, "The records go as back as 1900" could be improved to "The records go as far back as 1900".
Common error
Avoid using "as back as" when describing the duration of an event. While grammatically correct, it can sound awkward. Instead of saying, "I've known him as back as five years," opt for "I've known him for as long as five years" or "I've known him for five years".
