'incrementally-updated' originates from the combination of 'incremental' and 'update', where 'incremental' comes from the Latin 'incrementum', meaning 'growth', and 'update' is derived from 'up' and 'date', meaning 'to bring up to date'.

'incremental' evolved from the Latin 'incrementum' through Old French 'increment', and 'update' was formed in modern English by combining 'up' and 'date'.

Initially, 'incremental' meant 'growth', but over time it evolved to mean 'small steps', and 'update' has retained its meaning of 'bringing up to date'.
