The duration of the time travel window that was in place at the time of deletion is used for a deleted table or dataset. Tables that have been deleted before a change in the time travel window duration, for instance, are still only recoverable for a period of two days if you start with a two-day window and extend it to seven days. According to TPX, errors or misuses by humans, including social engineering, account for 74% of data breaches. In a similar vein, tables that were deleted before the modification remain recoverable for five more days if you have a five-day time travel window and decide to shorten it to three days. You cannot modify the time travel window to recover deleted data until it is undeleted because time travel windows are configured at the dataset level.
