### Create DB from snapshot
#### Creating an RDS Stack From a Snapshot with the Console
Screenshot of this change type in the AMS console:
![\[Interface for creating an Amazon RDS instance from a snapshot, showing description and version details.\]](http://docs.aws.amazon.com/managedservices/latest/ctref/images/guiRdsStackCreateFrmSnpshtCT.png)
How it works:
1. Navigate to the **Create RFC** page: In the left navigation pane of the AMS console click **RFCs** to open the RFCs list page, and then click **Create RFC**.
1. Choose a popular change type (CT) in the default **Browse change types** view, or select a CT in the **Choose by category** view.
+ **Browse by change type**: You can click on a popular CT in the **Quick create** area to immediately open the **Run RFC** page. Note that you cannot choose an older CT version with quick create.
To sort CTs, use the **All change types** area in either the **Card** or **Table** view. In either view, select a CT and then click **Create RFC** to open the **Run RFC** page. If applicable, a **Create with older version** option appears next to the **Create RFC** button.
+ **Choose by category**: Select a category, subcategory, item, and operation and the CT details box opens with an option to **Create with older version** if applicable. Click **Create RFC** to open the **Run RFC** page.
1. On the **Run RFC** page, open the CT name area to see the CT details box. A **Subject** is required (this is filled in for you if you choose your CT in the **Browse change types** view). Open the **Additional configuration** area to add information about the RFC.
In the **Execution configuration** area, use available drop-down lists or enter values for the required parameters. To configure optional execution parameters, open the **Additional configuration** area.
1. When finished, click **Run**. If there are no errors, the **RFC successfully created** page displays with the submitted RFC details, and the initial **Run output**.
1. Open the **Run parameters** area to see the configurations you submitted. Refresh the page to update the RFC execution status. Optionally, cancel the RFC or create a copy of it with the options at the top of the page.
#### Creating an RDS Stack From a Snapshot with the CLI
How it works:
1. Use either the Inline Create (you issue a `create-rfc` command with all RFC and execution parameters included), or Template Create (you create two JSON files, one for the RFC parameters and one for the execution parameters) and issue the `create-rfc` command with the two files as input. Both methods are described here.
1. Submit the RFC: `aws amscm submit-rfc --rfc-id ID` command with the returned RFC ID.
Monitor the RFC: `aws amscm get-rfc --rfc-id ID` command.
To check the change type version, use this command:
```
aws amscm list-change-type-version-summaries --filter Attribute=ChangeTypeId,Value=CT_ID
```
**Note**
You can use any `CreateRfc` parameters with any RFC whether or not they are part of the schema for the change type. For example, to get notifications when the RFC status changes, add this line, `--notification "{\"Email\": {\"EmailRecipients\" : [\"email@example.com\"]}}"` to the RFC parameters part of the request (not the execution parameters). For a list of all CreateRfc parameters, see the [AMS Change Management API Reference](https://docs.aws.amazon.com/managedservices/latest/ApiReference-cm/API_CreateRfc.html).
Backup is enabled on RDS instances with a default backup retention period of 7 days (`RDSBackups` and `RDSBackupRetentionPeriod`).
RDS stacks do not require a grant access RFC to access them, and are instead accessed using the username and password you provided when you created the stack.
**Note**
You can add up to 50 tags.
*INLINE CREATE*:
Issue the create RFC command with execution parameters provided inline (escape quotation marks when providing execution parameters inline), and then submit the returned RFC ID. For example, you can replace the contents with something like this:
```
create-rfc --change-type-id "ct-20san5sgtwd9e" --change-type-version "2.0" --title "RDS-Create-FrmSS-QC-RFC" --execution-parameters "{\"Description\":\"My RDS DB From SS\", \"VpcId\":\"VPC_ID\", \"StackTemplateId\":\"stm-siqajx00000000000\", \"Name\":\"RDS-Create-FrmSS-QC\", \"TimeoutInMinutes\":60, \"Parameters\":{ \"DBSnapshotIdentifier\":\"DB_ID\", \"DBSubnetIds\":[\"SUBNET_ID\",\"SUBNET_ID\"]}}"
```
*TEMPLATE CREATE*:
1. Output the execution parameters for this change type (ct-20san5sgtwd9e) to a JSON file named CreateRdsFSParams.json.
```
aws amscm get-change-type-version --change-type-id "ct-20san5sgtwd9e" --query "ChangeTypeVersion.ExecutionInputSchema" --output text > CreateRdsFSParams.json
```
1. Modify and save the execution parameters JSON file. For example, you can replace the contents with something like this:
Oracle example:
```
{
"Description": "Create-RDS-DB",
"VpcId": "VPC_ID",
"StackTemplateId": "stm-siqajx00000000000",
"Name": "My-RDS-DB",
"TimeoutInMinutes": 60,
"Parameters": {
"DBSnapshotIdentifier": rds:memzlbcde0abcd-2018-05-21-11-58,
"DBInstanceIdentifer": "MyRds",
"DBSubnetIds": ["PRIVATE_AZ1_SUBNET", "PRIVATE_AZ2_SUBNET"]
}
}
```
1. Output the JSON template to a file in your current folder; this example names it CreateRdsRfc.json:
```
aws amscm create-rfc --generate-cli-skeleton > CreateRdsRfc.json
```
1. Modify and save the CreateRdsRfc.json file. For example, you can replace the contents with something like this:
```
{
"ChangeTypeVersion": "2.0",
"ChangeTypeId": "ct-20san5sgtwd9e",
"Title": "RDS-Create-RFC"
}
```
1. Create the RFC, specifying the execution parameters file and the CreateRdsRfc file:
```
aws amscm create-rfc --cli-input-json file://CreateRdsRfc.json --execution-parameters file://CreateRdsParams.json
```
You receive the ID of the new RFC in the response and can use it to submit and monitor the RFC. Until you submit it, the RFC remains in the editing state and does not start.
1. To view the RDS, look in the execution output: Use the "stack\$1id" to view the RDS in the Cloud Formation Console. To create a Delete Stack or Update RDS RFC, use the first part of the DatabaseEndpoint (the DB instance ID) to create a Reboot RDS RFC, use the entire DatabaseEndpoint to programmatically access the RDS DB.
1. You are now able to manage the database via a database management tool such as SQL server management studio. You do not have to request access from AMS.
#### Tips
**Note**
You can't restore a DB instance from a DB snapshot that is both shared and encrypted. Instead, you can make a copy of the DB snapshot and restore the DB instance from the copy. To copy the shared snapshot, use the [RDS Snapshot \$1 Copy](https://docs.aws.amazon.com/managedservices/latest/ctref/deployment-advanced-rds-snapshot-copy.html) CT.
This CT is now at version 2, with new parameters, **DBDomain**, **DBDomainIAMRoleName**, and **DBEngine**. Additionally, The v1 of the CT would initiate the stack launch and return the stackId immediately, but not wait for the stack to finish launching. The v2 of the CT waits for the stack to finish launching before marking the RFC as successful or failed.
You can add up to 50 tags, but to do so you must enable the **Additional configuration** view.
