# POST Data Preservation in Files or Cache

When [Enable POST Data Preservation](org.forgerock.agents.post.data.preservation.enabled.html) is `true`, this property determines how POST data is saved:

`true`: Save POST data to files

`false` (default): Save POST data to the in-memory cache

Files are stored in the [POST Data Preservation File Directory](org.forgerock.agents.pdp.directory.html). Expired files are removed at the interval given by [POST Data Preservation Directory Sweep Interval](org.forgerock.agents.pdp.directory.sweep.seconds.html).
