SHARING A DB SNAPSHOT

PDFRSS

Using Amazon RDS, you can share a manual DB snapshot in the following ways:

* Sharing a manual DB snapshot, whether encrypted or unencrypted, enables
authorized AWS accounts to copy the snapshot.

* Sharing an unencrypted manual DB snapshot enables authorized AWS accounts to
directly restore a DB instance from the snapshot instead of taking a copy of
it and restoring from that. However, 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.

NOTE

To share an automated DB snapshot, create a manual DB snapshot by copying the
automated snapshot, and then share that copy. This process also applies to AWS
Backup–generated resources.

For more information on copying a snapshot, see Copying a DB snapshot. For more
information on restoring a DB instance from a DB snapshot, see Restoring from a
DB snapshot.

You can share a manual snapshot with up to 20 other AWS accounts.

The following limitations apply when sharing manual snapshots with other AWS
accounts:

* When you restore a DB instance from a shared snapshot using the AWS Command
Line Interface (AWS CLI) or Amazon RDS API, you must specify the Amazon
Resource Name (ARN) of the shared snapshot as the snapshot identifier.

* You can't share a DB snapshot that uses an option group with permanent or
persistent options, except for Oracle DB instances that have the Timezone or
OLS option (or both).

A permanent option can't be removed from an option group. Option groups with
persistent options can't be removed from a DB instance once the option group
has been assigned to the DB instance.

The following table lists permanent and persistent options and their related
DB engines.

Option name Persistent Permanent DB engine TDE Yes No Microsoft SQL Server
Enterprise Edition TDE Yes Yes Oracle Enterprise Edition Timezone Yes Yes

Oracle Enterprise Edition

Oracle Standard Edition

Oracle Standard Edition One

Oracle Standard Edition 2

For Oracle DB instances, you can copy shared DB snapshots that have the
Timezone or OLS option (or both). To do so, specify a target option group
that includes these options when you copy the DB snapshot. The OLS option is
permanent and persistent only for Oracle DB instances running Oracle version
12.2 or higher. For more information about these options, see Oracle time
zone and Oracle Label Security.

* You can't share a snapshot of a Multi-AZ DB cluster.

SHARING A SNAPSHOT

You can share a DB snapshot using the AWS Management Console, the AWS CLI, or
the RDS API.

Using the Amazon RDS console, you can share a manual DB snapshot with up to 20
AWS accounts. You can also use the console to stop sharing a manual snapshot
with one or more accounts.

TO SHARE A MANUAL DB SNAPSHOT BY USING THE AMAZON RDS CONSOLE

1. Sign in to the AWS Management Console and open the Amazon RDS console at
https://console.aws.amazon.com/rds/.

2. In the navigation pane, choose Snapshots.

3. Select the manual snapshot that you want to share.

4. For Actions, choose Share snapshot.

5. Choose one of the following options for DB snapshot visibility.

* If the source is unencrypted, choose Public to permit all AWS accounts to
restore a DB instance from your manual DB snapshot, or choose Private to
permit only AWS accounts that you specify to restore a DB instance from
your manual DB snapshot.

WARNING

If you set DB snapshot visibility to Public, all AWS accounts can restore
a DB instance from your manual DB snapshot and have access to your data.
Do not share any manual DB snapshots that contain private information as
Public.

For more information, see Sharing public snapshots.

* If the source is encrypted, DB snapshot visibility is set as Private
because encrypted snapshots can't be shared as public.

NOTE

Snapshots that have been encrypted with the default AWS KMS key can't be
shared. For information on how to work around this issue, see Sharing
encrypted snapshots.

6. For AWS Account ID, enter the AWS account identifier for an account that you
want to permit to restore a DB instance from your manual snapshot, and then
choose Add. Repeat to include additional AWS account identifiers, up to 20
AWS accounts.

If you make an error when adding an AWS account identifier to the list of
permitted accounts, you can delete it from the list by choosing Delete at
the right of the incorrect AWS account identifier.

7. After you have added identifiers for all of the AWS accounts that you want
to permit to restore the manual snapshot, choose Save to save your changes.

Using the Amazon RDS console, you can share a manual DB snapshot with up to 20
AWS accounts. You can also use the console to stop sharing a manual snapshot
with one or more accounts.

TO SHARE A MANUAL DB SNAPSHOT BY USING THE AMAZON RDS CONSOLE

1. Sign in to the AWS Management Console and open the Amazon RDS console at
https://console.aws.amazon.com/rds/.

2. In the navigation pane, choose Snapshots.

3. Select the manual snapshot that you want to share.

4. For Actions, choose Share snapshot.

5. Choose one of the following options for DB snapshot visibility.

WARNING

For more information, see Sharing public snapshots.

* If the source is encrypted, DB snapshot visibility is set as Private
because encrypted snapshots can't be shared as public.

NOTE

Snapshots that have been encrypted with the default AWS KMS key can't be
shared. For information on how to work around this issue, see Sharing
encrypted snapshots.

If you make an error when adding an AWS account identifier to the list of
permitted accounts, you can delete it from the list by choosing Delete at
the right of the incorrect AWS account identifier.

7. After you have added identifiers for all of the AWS accounts that you want
to permit to restore the manual snapshot, choose Save to save your changes.

To share a DB snapshot, use the aws rds modify-db-snapshot-attribute command.
Use the --values-to-add parameter to add a list of the IDs for the AWS accounts
that are authorized to restore the manual snapshot.

EXAMPLE OF SHARING A SNAPSHOT WITH A SINGLE ACCOUNT

The following example enables AWS account identifier 123456789012 to restore the
DB snapshot named db7-snapshot.

For Linux, macOS, or Unix:

aws rds modify-db-snapshot-attribute \
--db-snapshot-identifier db7-snapshot \
--attribute-name restore \
--values-to-add 123456789012

For Windows:

aws rds modify-db-snapshot-attribute ^
--db-snapshot-identifier db7-snapshot ^
--attribute-name restore ^
--values-to-add 123456789012

EXAMPLE OF SHARING A SNAPSHOT WITH MULTIPLE ACCOUNTS

The following example enables two AWS account identifiers, 111122223333 and
444455556666, to restore the DB snapshot named manual-snapshot1.

For Linux, macOS, or Unix:

aws rds modify-db-snapshot-attribute \
--db-snapshot-identifier manual-snapshot1 \
--attribute-name restore \
--values-to-add {"111122223333","444455556666"}

For Windows:

aws rds modify-db-snapshot-attribute ^
--db-snapshot-identifier manual-snapshot1 ^
--attribute-name restore ^
--values-to-add "[\"111122223333\",\"444455556666\"]"

NOTE

When using the Windows command prompt, you must escape double quotes (") in JSON
code by prefixing them with a backslash (\).

To list the AWS accounts enabled to restore a snapshot, use the
describe-db-snapshot-attributes AWS CLI command.

To list the AWS accounts enabled to restore a snapshot, use the
describe-db-snapshot-attributes AWS CLI command.

You can also share a manual DB snapshot with other AWS accounts by using the
Amazon RDS API. To do so, call the ModifyDBSnapshotAttribute operation. Specify
restore for AttributeName, and use the ValuesToAdd parameter to add a list of
the IDs for the AWS accounts that are authorized to restore the manual snapshot.

To make a manual snapshot public and restorable by all AWS accounts, use the
value all. However, take care not to add the all value for any manual snapshots
that contain private information that you don't want to be available to all AWS
accounts. Also, don't specify all for encrypted snapshots, because making such
snapshots public isn't supported.

To list all of the AWS accounts permitted to restore a snapshot, use the
DescribeDBSnapshotAttributes API operation.

RDS API

To list all of the AWS accounts permitted to restore a snapshot, use the
DescribeDBSnapshotAttributes API operation.

SHARING PUBLIC SNAPSHOTS

You can also share an unencrypted manual snapshot as public, which makes the
snapshot available to all AWS accounts. Make sure when sharing a snapshot as
public that none of your private information is included in the public snapshot.

When a snapshot is shared publicly, it gives all AWS accounts permission both to
copy the snapshot and to create DB instances from it.

You aren't billed for the backup storage of public snapshots owned by other
accounts. You're billed only for snapshots that you own.

If you copy a public snapshot, you own the copy. You're billed for the backup
storage of your snapshot copy. If you create a DB instance from a public
snapshot, you're billed for that DB instance. For Amazon RDS pricing
information, see the Amazon RDS product page.

You can delete only the public snapshots that you own. To delete a shared or
public snapshot, make sure to log into the AWS account that owns the snapshot.

VIEWING PUBLIC SNAPSHOTS OWNED BY OTHER AWS ACCOUNTS

You can view public snapshots owned by other accounts in a particular AWS Region
on the Public tab of the Snapshots page in the Amazon RDS console. Your
snapshots (those owned by your account) don't appear on this tab.

TO VIEW PUBLIC SNAPSHOTS

1. Open the Amazon RDS console at https://console.aws.amazon.com/rds/.

2. In the navigation pane, choose Snapshots.

3. Choose the Public tab.

The public snapshots appear. You can see which account owns a public
snapshot in the Owner column.

NOTE

You might have to modify the page preferences, by selecting the gear icon at
the upper right of the Public snapshots list, to see this column.

VIEWING YOUR OWN PUBLIC SNAPSHOTS

You can use the following AWS CLI command (Unix only) to view the public
snapshots owned by your AWS account in a particular AWS Region.

aws rds describe-db-snapshots --snapshot-type public --include-public | grep account_number

The output returned is similar to the following example if you have public
snapshots.

"DBSnapshotArn": "arn:aws:rds:us-east-1:123456789012:snapshot:mysnapshot1",
"DBSnapshotArn": "arn:aws:rds:us-east-1:123456789012:snapshot:mysnapshot2",

NOTE

You might see duplicate entries for DBSnapshotIdentifier or
SourceDBSnapshotIdentifier.

SHARING PUBLIC SNAPSHOTS FROM DEPRECATED DB ENGINE VERSIONS

Restoring or copying public snapshots from deprecated DB engine versions isn't
supported.

The RDS for Oracle and RDS for PostgreSQL DB engines support upgrading DB
snapshot engine versions directly. You can upgrade your snapshots, then re-share
them publicly. For more information, see the following:

* Upgrading an Oracle DB snapshot

* Upgrading a PostgreSQL DB snapshot engine version

For other DB engines, perform the following steps to make your existing
unsupported public snapshot available to restore or copy:

1. Mark the snapshot as private.

2. Restore the snapshot.

3. Upgrade the restored DB instance to a supported engine version.

4. Create a new snapshot.

5. Re-share the snapshot publicly.

SHARING ENCRYPTED SNAPSHOTS

You can share DB snapshots that have been encrypted "at rest" using the AES-256
encryption algorithm, as described in Encrypting Amazon RDS resources.

The following restrictions apply to sharing encrypted snapshots:

* You can't share encrypted snapshots as public.

* You can't share Oracle or Microsoft SQL Server snapshots that are encrypted
using Transparent Data Encryption (TDE).

* You can't share a snapshot that has been encrypted using the default KMS key
of the AWS account that shared the snapshot.

To work around the default KMS key issue, perform the following tasks:

1. Create a customer managed key and give access to it.

2. Copy and share the snapshot from the source account.

3. Copy the shared snapshot in the target account.

CREATE A CUSTOMER MANAGED KEY AND GIVE ACCESS TO IT

First you create a custom KMS key in the same AWS Region as the encrypted DB
snapshot. While creating the customer managed key, you give access to it for
another AWS account.

TO CREATE A CUSTOMER MANAGED KEY AND GIVE ACCESS TO IT

1. Sign in to the AWS Management Console from the source AWS account.

2. Open the AWS KMS console at https://console.aws.amazon.com/kms.

3. To change the AWS Region, use the Region selector in the upper-right corner
of the page.

4. In the navigation pane, choose Customer managed keys.

5. Choose Create key.

6. On the Configure key page:

1. For Key type, select Symmetric.

2. For Key usage, select Encrypt and decrypt.

3. Expand Advanced options.

4. For Key material origin, select KMS.

5. For Regionality, select Single-Region key.

6. Choose Next.

7. On the Add labels page:

1. For Alias. enter a display name for your KMS key, for example
share-snapshot.

2. (Optional) Enter a description for your KMS key.

3. (Optional) Add tags to your KMS key.

4. Choose Next.

8. On the Define key administrative permissions page, choose Next.

9. On the Define key usage permissions page:

1. For Other AWS accounts, choose Add another AWS account.

2. Enter the ID of the AWS account to which you want to give access.

You can give access to multiple AWS accounts.

3. Choose Next.

10. Review your KMS key, then choose Finish.

COPY AND SHARE THE SNAPSHOT FROM THE SOURCE ACCOUNT

Next you copy the source DB snapshot to a new snapshot using the customer
managed key. Then you share it with the target AWS account.

TO COPY AND SHARE THE SNAPSHOT

1. Sign in to the AWS Management Console from the source AWS account.

2. Open the Amazon RDS console at https://console.aws.amazon.com/rds/

3. In the navigation pane, choose Snapshots.

4. Select the DB snapshot you want to copy.

5. For Actions, choose Copy snapshot.

6. On the Copy snapshot page:

1. For Destination Region, choose the AWS Region where you created the
customer managed key in the previous procedure.

2. Enter the name of the DB snapshot copy in New DB Snapshot Identifier.

3. For AWS KMS key, choose the customer managed key that you created.

4. Choose Copy snapshot.

7. When the snapshot copy is available, select it.

8. For Actions, choose Share snapshot.

9. On the Snapshot permissions page:

1. Enter the AWS account ID with which you're sharing the snapshot copy,
then choose Add.

2. Choose Save.

The snapshot is shared.

COPY THE SHARED SNAPSHOT IN THE TARGET ACCOUNT

Now you can copy the shared snapshot in the target AWS account.

TO COPY THE SHARED SNAPSHOT

1. Sign in to the AWS Management Console from the target AWS account.

2. Open the Amazon RDS console at https://console.aws.amazon.com/rds/

3. In the navigation pane, choose Snapshots.

4. Choose the Shared with me tab.

5. Select the shared snapshot.

6. For Actions, choose Copy snapshot.

7. Choose your settings for copying the snapshot as in the previous procedure,
but use an AWS KMS key that belongs to the target account.

Choose Copy snapshot.

STOPPING SNAPSHOT SHARING

To stop sharing a DB snapshot, you remove permission from the target AWS
account.

TO STOP SHARING A MANUAL DB SNAPSHOT WITH AN AWS ACCOUNT

1. Sign in to the AWS Management Console and open the Amazon RDS console at
https://console.aws.amazon.com/rds/.

2. In the navigation pane, choose Snapshots.

3. Select the manual snapshot that you want to stop sharing.

4. Choose Actions, and then choose Share snapshot.

5. To remove permission for an AWS account, choose Delete for the AWS account
identifier for that account from the list of authorized accounts.

6. Choose Save to save your changes.
