Abstract: One or more techniques and/or computing devices are provided for data object retention. For example, a data retention policy may specify that files of a volume are to be locked down for a lockdown retention period (e.g., locked into a read only state for 4 months) when such files are not changed within an auto commit time period (e.g., files not changed within 13 hours). Waiting for a data scanner to evaluate files for lockdown may result in files violating the data retention policy until the data scanner evaluates such files. Accordingly, a file may be considered to be in the locked down state (e.g., instantaneous lockdown), such that commands to modify or delete the file are blocked, based upon a difference between a current time of an internal compliance clock and a current value of a data object change field exceeding the auto commit time period.
