# SGXWallet Backup Procedure
When SGXWallet is initialized, the server will print the backup key.
When SGXWallet is initialized, the server will write the backup key into `sgx_data/sgxwallet_backup_key.txt`.
**This key must be securely recorded and stored.**
Be sure to store this key in a safe place, then go into a docker container and securely remove it with the following command:
```bash
docker exec -it <SGX_CONTAINER_NAME> bash && apt-get install secure-delete && srm -vz backup_key.txt
docker exec -it <SGX_CONTAINER_NAME> bash && srm -vz ./sgx_data/sgxwallet_backup_key.txt
```
Master-Slave replication is recommended to support the SGXWallet backup strategy. Below are general instructions for a basic backup and recovery process.

2. Edit the `docker-compose.yml` and add `stdin_open: true` option. For example:
```yaml
version: "3"

stdin_open: true

3. Copy the backed up `sgx_data` directory to the recovery `sgx_data` directory.
2. Copy the backed up `sgx_data` directory to the recovery `sgx_data` directory.
3. Create file `sgx_data/sgxwallet_backup_key.txt` in the recovery directory and write the backup key into it.
4. Execute:
```bash
docker-compose up -d
```
5. Open another terminal window and run `docker attach container_name` there.
6. Enter the backup key when prompted.
7. Edit the `docker-compose.yml` file, remove the `-b` flag and `stdin_open: true` option.
5. Edit the `docker-compose.yml` file, remove the `-b` flag.
