 - SQLite, MySQL, PostgreSQL, CockroachDB, Bolt (key/value store in pure Go) and in-memory data providers are supported.
 - Chroot isolation for local accounts. Cloud-based accounts can be restricted to a certain base path.
 - Per user and per directory virtual permissions, for each exposed path you can allow or deny: directory listing, upload, overwrite, download, delete, rename, create directories, create symlinks, change owner/group/file mode.
- [REST API](./docs/rest-api.md) for users and folders management, backup, restore and real time reports of the active connections with possibility of forcibly closing a connection.
+- [REST API](./docs/rest-api.md) for users and folders management, data retention, backup, restore and real time reports of the active connections with possibility of forcibly closing a connection.
 - [Web based administration interface](./docs/web-admin.md) to easily manage users, folders and connections.
 - [Web client interface](./docs/web-client.md) so that end users can change their credentials and browse their files.
 - Public key and password authentication. Multiple public keys per user are supported.

-SFTPGo exposes REST API to manage, backup, and restore users and folders, and to get real time reports of the active connections with the ability to forcibly close a connection.
+SFTPGo exposes REST API to manage, backup, and restore users and folders, data retention, and to get real time reports of the active connections with the ability to forcibly close a connection.

 If quota tracking is enabled in the configuration file, then the used size and number of files are updated each time a file is added/removed. If files are added/removed not using SFTP/SCP, or if you change `track_quota` from `2` to `1`, you can rescan the users home dir and update the used quota using the REST API.

@ -35,6 +35,7 @@ You can create other administrator and assign them the following permissions:
 - manage API keys
 - manage system
 - manage admins
+- manage data retention

 You can also restrict administrator access based on the source IP address. If you are running SFTPGo behind a reverse proxy you need to allow both the proxy IP address and the real client IP.

@ -62,6 +63,35 @@ API keys are not allowed for the following REST APIs:

 Please keep in mind that using an API key not associated with any administrator it is still possible to create a new administrator, with full permissions, and then impersonate it: be careful if you share unassociated API keys with third parties and with the `manage adminis` permission granted, they will basically allow full access, the only restriction is that the impersonated admin cannot be modified.

+The data retention APIs allow you to define per-folder retention policies for each user. To clarify this concept let's show an example, a data retention check accepts a POST body like this one:
+
+```json
+[
+  {
+    "path": "/folder1",
+    "retention": 72
+  },
+  {
+    "path": "/folder1/subfolder",
+    "retention": 0
+  },
+  {
+    "path": "/folder2",
+    "retention": 24
+  }
+]
+```
+
+In the above example we asked to SFTPGo:
+
+- to delete all the files with modification time older than 72 hours in `/folder1`
+- to exclude `/folder1/subfolder`, no files will be deleted here
+- to delete all the files with modification time older than 24 hours in `/folder2`
+
+You can find an example script that shows how to manage data retention [here](../examples/data-retention). Checks the REST API schema for full details.
+
+:warning: Deleting files is an irreversible action, please make sure you fully understand what you are doing before using this feature, you may have users with overlapping home directories or virtual folders shared between multiple users, it is relatively easy to inadvertently delete files you need.
+
 The OpenAPI 3 schema for the exposed API can be found inside the source tree: [openapi.yaml](../httpd/schema/openapi.yaml "OpenAPI 3 specs"). If you want to render the schema without importing it manually, you can explore it on [Stoplight](https://sftpgo.stoplight.io/docs/sftpgo/openapi.yaml).

 You can generate your own REST client in your preferred programming language, or even bash scripts, using an OpenAPI generator such as [swagger-codegen](https://github.com/swagger-api/swagger-codegen) or [OpenAPI Generator](https://openapi-generator.tech/).

+# File retention policies
+
+The `checkretention` example script shows how to use the SFTPGo REST API to manage data retention.
+
+:warning: Deleting files is an irreversible action, please make sure you fully understand what you are doing before using this feature, you may have users with overlapping home directories or virtual folders shared between multiple users, it is relatively easy to inadvertently delete files you need.
+
+The example shows how to setup a really simple retention policy, for each user it sends this request:
+
+```json
+[
+  {
+    "path": "/",
+    "retention": 168,
+    "delete_empty_dirs": true,
+    "ignore_user_permissions": false
+  }
+]
+```
+
+so alls files with modification time older than 168 hours (7 days) will be deleted. Empty directories will be removed and the check will respect user's permissions, so if the user cannot delete a file/folder it will be skipped.
+
+You can define different retention policies per-user and per-folder and you can exclude a folder setting the retention to `0`.
+
+You can use this script as a starting point, please edit it according to your needs.
+
+The script is written in Python and has the following requirements:
+
+- python3 or python2
+- python [Requests](https://requests.readthedocs.io/en/master/) module
+
+The provided example tries to connect to an SFTPGo instance running on `127.0.0.1:8080` using the following credentials:
+
+- username: `admin`
+- password: `password`
