Backlog

The remaining contracted work not yet delivered. Total contract value is not necessarily remaining backlog if part of the work has already been performed.

Backlog in round numbers

The stated Hanil example cites 7.20m of signed maintenance contracts and about seven months of service revenue. Interpreting those figures as backlog requires separating delivered from undelivered work. A months-of-coverage estimate also depends on the measurement date and the revenue basis used.
