# Backup and Restore

In case database backup and restore is required, please follow the steps below. Our team is here to assist you throughout the process.

<Tip>
  This is available for paid tiers only. We hope to make this process self-serve
  soon.
</Tip>

## 1. Notify Us

Send a message to our team via Slack (if we have set up one for you) or email at [support@thenile.dev](mailto:support@thenile.dev) and include **URGENT** in the title. Include the following details to expedite the recovery process:

* Database name
* Approximate time when the issue occurred
* Do you wish to restore to new schema in same database or to a different database? (if a different database, please provide its name as well).

## 2. Acknowledgment

Once we receive your message, we will acknowledge it within **15 minutes**. If you do not receive an acknowledgment, please follow up.

## 3. Backup Availability

We take **three backups daily** to ensure your data is well-protected. Upon your request, an appropriate backup, based on the time when the data issue occurred, will be restored in a separate schema within your database or alternatively into the original schema in an empty database of your choice.

In the case of separate schema, the backup schema will have a name in the format: `<original_schema_name>_bkp`.
For example, if your original schema is `sales_data`, the backup schema will be named: `sales_data_bkp`

## 4. How to Restore Data

<Tip>
  Only needed if data is restored within the same database into another schema
</Tip>

You can restore the data from the backup schema using SQL commands. Below is an example query to copy data back to the original schema:

```sql theme={null}
-- Recover data for a specific tenant:
SET nile.tenant_id='018ff561-ae16-7c9e-93c6-8482f9952c4f';
INSERT INTO expense_report_items
SELECT * FROM public_bkp.expense_report_items;

-- recover data for shared table
RESET nile.tenant_id;
INSERT INTO flights select * from flights;

-- recover data for multiple tenants:

-- 1. generate statements:
RESET nile.tenant_id;
SELECT 'SET nile.tenant_id='''||id||'''; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;' from tenants where name like '%customer%';

-- 2. Run the resulting statements:
 SET nile.tenant_id='179027f2-e184-4df7-a568-2be746898be2'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='018ff04c-9dfe-7fbd-8d1c-96ccdbe24e11'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='018ff04d-7ded-7719-a2d3-79f65d19f2e8'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='108124a5-2e34-418a-9735-b93082e9fbf2'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='84a4358a-15a4-42ba-8606-ca948fb730c2'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='a02748b7-76c9-4765-b230-dea566e38e5d'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
 SET nile.tenant_id='cea8b9b8-ec0a-4144-ae3a-b67834079951'; INSERT INTO expense_report_items SELECT * FROM public_bkp.expense_report_items;
```
