|
|||
---
|
||||
Synapse includes a Python command to export data for a specific user. It takes the homeserver
|
||||
configuration file and the full Matrix ID of the user to export:
|
||||
|
||||
```console
|
||||
python -m synapse.app.admin_cmd -c <config_file> export-data <user_id>
|
||||
python -m synapse.app.admin_cmd -c <config_file> export-data <user_id> --output-directory <directory_path>
|
||||
```
|
||||
|
||||
If you uses [Poetry](../../development/dependencies.md#managing-dependencies-with-poetry)
|
||||
to run Synapse:
|
||||
|
||||
```console
|
||||
poetry run python -m synapse.app.admin_cmd -c <config_file> export-data <user_id> --output-directory <directory_path>
|
||||
```
|
||||
|
||||
The directory to store the export data in can be customised with the
|
||||
`--output-directory` parameter; ensure that the provided directory is
|
||||
empty. If this parameter is not provided, Synapse defaults to creating
|
||||
a temporary directory (which starts with "synapse-exfiltrate") in `/tmp`,
|
||||
`/var/tmp`, or `/usr/tmp`, in that order.
|
||||
|
||||
The exported data has the following layout:
|
||||
|
||||
```
|
||||
output-directory
|
||||
├───rooms
|

There are two exceptions when it might be sensible to delete your database and start again:

* You have *never* joined any rooms which are federated with other servers. For instance, a local deployment which the outside world can't talk to.
|
||||
* You are changing the `server_name` in the homeserver configuration. In effect this makes your server a completely new one from the point of view of the network, so in this case it makes sense to start with a clean database.
