Manage bucket

Available in Classic and VPC

A bucket created in Ncloud Storage is a space to store objects. Once you create at least 1 bucket, the Ncloud Storage subscription starts.

To create and manage buckets in the NAVER Cloud Platform console:

Create bucket.

To create a bucket in the Ncloud Storage service:

1. From the NAVER Cloud Platform console, navigate to > Services > Storage > Ncloud Storage > Bucket Management.
2. Click [Create bucket] in the Bucket Management interface.
3. Enter the required information in the Enter basic information step.
   • Region: Specify the Region where you will create the bucket.
   • Bucket name: Enter the name of the bucket to create. (See Bucket name rules.)
     • Once a bucket has been created, you cannot change its name or Region.
4. Click [Next].
5. Select whether to enable bucket versioning in the Manage settings step.
   • Bucket versioning: Once enabled, you cannot disable it. You can only pause the feature when you are not using it.
   • For more information about version management, see Bucket versioning guide.
6. After confirming the information you entered, click [Create bucket].
7. A bucket is created.
   • You can create up to 100 buckets by Region.

Bucket name rules

The string rules for bucket names in Ncloud Storage are as follows:

• You must enter a unique name for each Region. If there is an identical bucket name, you cannot register it.
• You can enter between 3 and 63 characters.
• You can only use lowercase letters, numbers, and/or hyphens (-). It must start and end with a letter or a number.
• You cannot use the following prefixes: xn--, sthree-, sthree-configurator, and amzn-s3-demo-.
• You cannot use the following suffixes: -s3alias, --ol-s3, .mrap, and --x-s3.

Manage bucket

You can set options or view details in the bucket management menu. To manage buckets:

1. From the NAVER Cloud Platform console, navigate to > Services > Storage > Ncloud Storage.
2. Select a bucket from the bucket list on the Bucket Management interface.
3. View the bucket details, bucket versioning, lifecycle management, and encryption management status.

Delete bucket

To delete buckets:

1. Select the bucket you want to delete from the bucket list and click [Delete bucket].
2. Enter the bucket name in the Delete bucket popup, then click [OK].
3. Check that the task is completed in the Delete popup and close the window.

Cancel bucket deletion

During bucket deletion, the Cancel bucket deletion button is enabled so that you can cancel the deletion. To cancel bucket deletion, click [Save] in the Cancel bucket deletion popup.

Details

The following are the bucket details you can view on the console:

• Bucket name: Name of the selected bucket.
• Size: Total size of objects stored in the selected bucket.
• Number of objects: Total number of objects stored in the selected bucket.
• Whether there are incomplete multipart uploads: If you upload large-scale objects using multipart upload, whether any incomplete multipart upload remain.

Bucket versioning

Version management is a feature that stores multiple versions of a file for 1 object. When the bucket versioning feature is enabled, all versions of objects stored in the bucket are reserved and can be retrieved and restored. This allows you to easily restore an object to a previous version in case of unintended actions, like accidentally deleting it.

To enable bucket versioning feature:

Enable in the bucket creation step

In Step 2 of bucket creation, Select whether to enable bucket versioning under Manage settings > Bucket versioning.

Enable bucket versioning in the bucket list

1. Select the bucket from the bucket list and click in the Bucket versioning component.
2. Select Enable in the bucket versioning popup.
3. Click [Apply].
4. The bucket versioning feature is enabled.

Lifecycle management

Lifecycle management is a feature that allows you to use the storage cost efficiently by setting task rules for objects stored in the bucket to transfer the object to a lower-cost storage class or by automatically deleting the expired objects. You can set up to 1,000 rules per bucket. The same rules are applied to the objects stored after the rules are set.

Enable lifecycle management

To enable the lifecycle management feature:

1. Select the bucket from the bucket list and click in the Lifecycle management component.
2. In the Lifecycle management popup, select Add rules.
3. In the Add rules popup, set detailed rules and click [Save]. For more information about performing tasks, see Lifecycle management tasks.
4. The object transfer or expiration tasks are performed according to the rules you set. The same rules are applied to the objects stored after the rules are set.

Lifecycle management tasks

The types of tasks that can be performed through the lifecycle management settings are as follows:

• Switch the current version of the object: Move the latest version of an object to the specified storage class when the specified period or date is reached. However, the task is carried out only for objects larger than 128 KB.
  • You can configure the specific date option only through the API or CLI, and rules with a date cannot be edited in the console.
• Switch the previous version of the object: After the latest version of the object is switched to the previous version (after it becomes the non-current version of the object), move the object to the designated storage class when the designated time arrives. If you specify how many previous versions to keep, all previous versions beyond that number are moved to the specified storage class. However, the task is carried out only for objects larger than 128 KB.
• Delete the current version of the object: When the designated time arrives, delete the latest version of the object and add the deletion marker. Through this, the latest version of the object is switched to the previous version, and the deletion marker becomes the latest version.
  • Here, if the version of the object is more than 1 and the deletion marker is the latest version, the task is not carried out.
• Delete the previous version of the object: After the latest version of the object is switched to the previous version (after it becomes the non-current version of the object), permanently delete the previous version of the object when the designated time arrives. Objects deleted due to the deletion task can't be recovered.
• Delete the expired deletion marker: If the latest version of the object is the deletion marker and the previous version of the object doesn't exist (if the latest object is the only object version), you can delete the deletion marker.

Edit lifecycle management rules

You can edit the lifecycle rules you set.

1. Select the rule you want to edit from the list of rules in the lifecycle management popup, and click [Edit].
2. In the Edit rules popup, set detailed rules and click [OK].

Delete lifecycle management rules

You can delete the lifecycle rules you set.

1. Select the rule you want to delete from the list of rules in the lifecycle management popup, and click [Delete].
2. Check the instruction in the Delete popup and click [Delete].

Encryption management

Encryption management is a feature that encrypts and stores objects stored in the bucket. For all buckets created in Ncloud Storage, the server-side encryption using NCP-managed key (SSE-S3) is applied as the default encryption. If you want to use customer-provided keys for encryption (SSE-C), you can apply it through the API or CLI.
