+# Backups
+
+<Admonition />
+
+KV databases hosted on Deno Deploy can be continuously backed up to your own S3-compatible storage buckets. This is in
+addition to the replication and backups that we internally perform for all data stored in hosted Deno KV databases to ensure
+high availability and data durability.
+
+This backup happens continuously with very little lag, enabling _[point-in-time-recovery](https://en.wikipedia.org/wiki/Point-in-time_recovery)_
+and live replication. Enabling backup for KV databases unlocks various interesting use-cases:
+
+- Retrieving a consistent snapshot of your data at any point in time in the past
+- Running a read-only data replica independent of Deno Deploy
+- Pushing data into your favorite data pipeline by piping mutations into streaming platforms and analytical databases like Kafka, BigQuery and ClickHouse
+
+## Configuring backup to Amazon S3
+
+First you must create a bucket on AWS:
+
+import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';
+
+<Tabs groupId="aws-tool">
+<TabItem value="console" label="AWS Console" default>
+
+1. Go to the [AWS S3 console](https://s3.console.aws.amazon.com/s3/home)
+2. Click "Create bucket"
+3. Enter a bucket name and choose a AWS region, then scroll down and click "Next"
+
+
+</TabItem>
+<TabItem value="cli" label="AWS CLI">
+
+1. Install the [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html)
+2. Run `aws s3api create-bucket --bucket <bucket-name> --region <region> --create-bucket-configuration LocationConstraint=<region>` (replace `<bucket-name>` and `<region>` with your own values)
+
+
+</TabItem>
+</Tabs>
+
+Then, create an IAM policy with `PutObject` access to the bucket, attach it to
+an IAM user, and create access keys for that user:
+
+<Tabs groupId="aws-tool">
+<TabItem value="console" label="AWS Console" default>
+
+1. Go to the [AWS IAM console](https://console.aws.amazon.com/iam/home)
+2. Click "Policies" in the left sidebar
+3. Click on "Create policy"
+4. Select the "JSON" the policy editor and paste the following policy:
+   ```json
+   {
+     "Version": "2012-10-17",
+     "Statement": [
+       {
+         "Sid": "KVBackup",
+         "Effect": "Allow",
+         "Action": "s3:PutObject",
+         "Resource": "arn:aws:s3:::<bucket-name>/*"
+       }
+     ]
+   }
+   ```
+   Replace `<bucket-name>` with the name of the bucket you created earlier.
+5. Click "Review policy"
+6. Enter a name for the policy and click "Create policy"
+7. Click "Users" in the left sidebar
+8. Click "Add user"
+9. Enter a name for the user and click "Next"
+10. Click "Attach policies directly"
+11. Search for the policy you created earlier and click the checkbox next to it
+12. Click "Next"
+13. Click "Create user"
+14. Click on the user you just created
+15. Click "Security credentials" and then "Create access key"
+16. Select "Other", then click "Next"
+17. Enter a description for the access key and click "Create access key"
+18. Copy the access key ID and secret access key and save them somewhere safe.
+    You will need them later, and you will not be able to retrieve them again.
+
+</TabItem>
+<TabItem value="cli" label="AWS CLI">
+
+1. Copy the following command to your terminal, and replace `<bucket-name>` with
+   the name of the bucket you created earlier, then run it:
+   ```
+   aws iam create-policy --policy-name <policy-name> --policy-document '{"Version":"2012-10-17","Statement":[{"Sid":"KVBackup","Effect":"Allow","Action":"s3:PutObject","Resource":"arn:aws:s3:::<bucket-name>/*"}]}'
+   ```
+2. Copy the following command to your terminal, and replace `<user-name>` with
+   a name for the user you are creating, then run it:
+   ```
+   aws iam create-user --user-name <user-name>
+   ```
+3. Copy the following command to your terminal, and replace `<policy-arn>` with
+   the ARN of the policy you created in step 1, and `<user-name>` with
+   the name of the user you created in the previous step, then run it:
+   ```
+   aws iam attach-user-policy --policy-arn <policy-arn> --user-name <user-name>
+   ```
+4. Copy the following command to your terminal, and replace `<user-name>` with
+   the name of the user you created in step 2, then run it:
+   ```
+   aws iam create-access-key --user-name <user-name>
+   ```
+5. Copy the access key ID and secret access key and save them somewhere safe.
+   You will need them later, and you will not be able to retrieve them again.
+
+
+</TabItem>
+</Tabs>
+
+Now visit the [Deno Deploy dashboard](https://dash.deno.com), and click on the
+"KV" tab in your project. Scroll to the "Backup" section, and click on "AWS S3".
+Enter the bucket name, access key ID, and secret access key you created earlier,
+and the region the bucket is in. Then click "Save".
+
+<img
+  src={backupAddBucketToDash}
+  alt="add backup to dashboard"
+  style={{
+    height: "500px",
+  }}
+/>
+
+The backup will start immediately. Once the data has been backed up, and
+continous backup is active, you will see the status change to "Active".
+
+## Configuring backup to Google Cloud Storage
+
+Google Cloud Storage (GCS) is compatible with the S3 protocol, and can also be
+used as a backup target.
+
+First you must create a bucket on GCP:
+
+<Tabs groupId="gcp-tool">
+<TabItem value="console" label="GCP Console" default>
+
+1. Go to the [GCP Cloud Storage console](https://console.cloud.google.com/storage/browser)
+2. Click on "Create" in the top bar
+3. Enter a bucket name, choose a location, and click "Create"
+
+</TabItem>
+<TabItem value="cli" label="gcloud CLI">
+
+1. Install the [gcloud CLI](https://cloud.google.com/sdk/docs/install)
+2. Run `gcloud storage buckets create <bucket-name> --location <location>` (replace `<bucket-name>` and `<location>` with your own values)
+
+</TabItem>
+</Tabs>
+
+Then, create a service account with `Storage Object Admin` access to the bucket,
+and create an HMAC access key for the service account:
+
+<Tabs groupId="gcp-tool">
+<TabItem value="console" label="GCP Console" default>
+
+1. Go to the [GCP IAM console](https://console.cloud.google.com/iam-admin/iam)
+2. Click on "Service accounts" in the left sidebar
+3. Click on "Create service account"
+4. Enter a name for the service account and click "Done"
+5. Copy the email for the service account you just created. You will need it
+   later.
+6. Go to the [GCP Cloud Storage console](https://console.cloud.google.com/storage/browser)
+7. Click on the bucket you created earlier
+8. Click on "Permissions" in the toolbar
+9. Click "Grant access"
+10. Paste the email for the service account you copied earlier into the "New
+    principals" field
+11. Select "Storage Object Admin" from the "Select a role" dropdown
+12. Click "Save"
+13. Click on "Settings" in the left sidebar (still in the Cloud Storage console)
+14. Click on the "Interoperability" tab
+15. Click on "Create a key for a service account"
+16. Select the service account you created earlier
+17. Click "Create key"
+18. Copy the access key and secret access key and save them somewhere safe.
+    You will need them later, and you will not be able to retrieve them again.
+
+
+</TabItem>
+<TabItem value="cli" label="gcloud CLI">
+
+1. Run the following command, replacing `<service-account-name>` with a name for
+   the service account you are creating:
+   ```
+   gcloud iam service-accounts create <service-account-name>
+   ```
+2. Run the following command, replacing `<bucket-name>` with the name of the
+   bucket you created earlier, and `<service-account-email>` with the email of
+   the service account you created in the previous step:
+   ```
+   gsutil iam ch serviceAccount:<service-account-email>:objectAdmin gs://<bucket-name>
+   ```
+3. Run the following command, replacing `<service-account-email>` with the email
+   of the service account you created in the previous step:
+   ```
+   gcloud storage hmac create <service-account-email>
+   ```
+4. Copy the `accessId` and `secret` and save them somewhere safe. You will need
+   them later, and you will not be able to retrieve them again.
+
+
+</TabItem>
+</Tabs>
+
+Now visit the [Deno Deploy dashboard](https://dash.deno.com), and click on the
+"KV" tab in your project. Scroll to the "Backup" section, and click on "Google
+Cloud Storage". Enter the bucket name, access key ID, and secret access key you
+created earlier, and the region the bucket is in. Then click "Save".
+
+The backup will start immediately. Once the data has been backed up, and
+continous backup is active, you will see the status change to "Active".
+
+## Using backups
+
+S3 backups can be used with the `denokv` tool. Please refer to the
+[documentation](https://github.com/denoland/denokv) for more details.
