ApsaraVideo VOD:Manage storage buckets

Storage bucket types

ApsaraVideo VOD supports the VOD and OSS buckets. All features provided by ApsaraVideo VOD can be used on all media resources that are stored in VOD and OSS buckets. Examples of these features include media upload, transcoding (encryption included), snapshot capture, playback, and AI processing such as content moderation and media fingerprinting.

For more information about the differences between ApsaraVideo VOD buckets and Object Storage Service (OSS) buckets, see Storage overview.

Enable VOD buckets

After you activate ApsaraVideo VOD, you are assigned an independent VOD bucket in each region. You must enable the bucket before you can upload and manage media resources in a region. Other configurations are not required.

1. Log on to the ApsaraVideo VOD console.

2. In the left-side navigation pane, choose Configuration Management > Media Management > Storage.

3. In the upper-left corner of the page, select the desired region.

   

4. Click Enable VOD Buckets.

5. Select Redundancy Type.

   Standard locally redundant storage (LRS)

   LRS stores multiple copies of your data on multiple devices of different facilities in the same zone. LRS provides data durability and availability even if hardware failures occur.

   Important

   LRS stores multiple data copies in a single zone. If the zone becomes unavailable, data in the zone is inaccessible. If your business application requires higher availability, we recommend that you use zone-redundant storage (ZRS).

   ZRS

   ZRS stores multiple copies of your data across multiple zones in the same region. Even if one zone becomes unavailable, the data can still be accessed.

6. Wait until the bucket is enabled. You can use the bucket only after the system returns The bucket is enabled and the status of the bucket is Normal.

Switch from LRS to ZRS

LRS provides data redundancy within only one zone and may fail to meet increasing requirements on data durability and availability. To protect your business applications from zone-level failures, you can change the storage redundancy type of your buckets from LRS to ZRS. This section describes how to change the storage redundancy type of a bucket from LRS to ZRS.

Prerequisites

• Storage redundancy type changing is supported in the region where your bucket is located. This feature is supported in the following regions: China (Shanghai), China (Beijing), China (Shenzhen), China (Hong Kong), Japan (Tokyo), Singapore, Indonesia (Jakarta), and Germany (Frankfurt).

• The bucket whose storage type you want to change is an ApsaraVideo VOD bucket.

• The storage redundancy type of the bucket is LRS. You can switch the redundancy type of a bucket only from LRS to ZRS, not the other way around.

• After you change the storage type to ZRS, the redundancy types of Cold Archive and Deep Cold Archive objects remain LRS.

• The conversion of the storage redundancy type of a bucket takes a period of time to complete. The usage of the bucket is not affected during this period.

Usage notes

• Direction of change: You can change the storage redundancy type only from LRS to ZRS. You cannot change the storage redundancy type from ZRS to LRS.

• Change method: You can change the storage redundancy type in the ApsaraVideo VOD console.

• Time required for the change: The time required to change the storage redundancy type of a bucket varies based on factors such as the data size, number of objects, and number of parts in the bucket.

• Fees incurred: You are not charged for changing the storage redundancy type. However, you are charged storage fees based on ZRS instead of LRS after the storage redundancy type is changed. The unit price of ZRS is higher than that of LRS. For more information, see Media storage.

Procedure

To change the storage redundancy type of a bucket from LRS to ZRS, perform the following steps:

1. Log on to the ApsaraVideo VOD console.

2. In the left-side navigation pane, choose Configuration Management > Media Management > Storage. Buckets. On the Storage page, click the name of the desired bucket or Manage in the Actions column.

3. In the Basic Information section, click Convert to ZRS next to the Redundancy Type field.

4. In the Convert Redundancy Type from LRS to ZRS panel, check the estimated time required to complete the change and click Confirm.

5. In the message that appears, click OK.

The following table describes the possible states of a storage redundancy type change task.

Add user-created OSS buckets

If you have a large number of media files stored in an OSS bucket and these media files cannot be migrated to a VOD bucket, you can add the OSS bucket to ApsaraVideo VOD. This way, you can perform transcoding, snapshot capture, and playback operations on these media files.

• Existing resources: If the OSS bucket that you added to ApsaraVideo VOD contains existing media resources, you need to register these resources by calling the RegisterMedia operation. Then, you can use the transcoding, snapshot capture, and playback features provided by ApsaraVideo VOD.

• New resources: You can directly use features such as transcoding, snapshot capture, and playback on the media resources after you upload the resources to an OSS bucket that is added to ApsaraVideo VOD. No additional configurations are required.

Limits

• You cannot add OSS buckets in the China (Hong Kong) region. For more information about the regions in which you can add OSS buckets, see Regions.

• You can add up to 10 user-created OSS buckets to each region.

• You can add only OSS buckets whose storage class is Standard to ApsaraVideo VOD.

Prerequisites

• At least one user-created OSS bucket exists in your desired region. For more information, see How to create a bucket.

• Permissions are granted to allow ApsaraVideo VOD to access your OSS resources. You can go to the Cloud Resource Access Authorization page to authorize access.

Procedure

1. Log on to the ApsaraVideo VOD console.

2. In the left-side navigation pane, choose Configuration Management > Media Management > Storage.

3. In the upper-left corner of the page, select the desired region.

Specify a default bucket

If multiple buckets are available in a region, you can set one as the default bucket. All media resources uploaded to ApsaraVideo VOD will be stored in the default bucket unless specified otherwise.

1. Log on to the ApsaraVideo VOD console and select the desired region. In the left-side navigation pane, choose Configuration Management > Media Management > Storage.

2. Find the bucket that you want to set as the default one and click Set as Default in the Actions column.

Manage buckets

In the ApsaraVideo VOD console, you can view buckets, modify permissions, and delete or set default origin domain names for buckets.

In the ApsaraVideo VOD console, select the desired region and choose Configuration Management > Media Management > Storage. On the Storage page, click Manage in the Actions column.

• In the Basics section, view basic information about the bucket, such as the region and type.

• In the Permissions section, click Modify to modify the read and write permissions on the bucket.

  Note

  • If you specify Public Read and Private Write for a bucket, the corresponding address is permanently valid but is exposed to hotlinking and illegal downloads. If you specify Private Read and Write for a bucket, the corresponding address is valid for 3,600 seconds by default. You can call the GetPlayInfo operation to modify the validity period of the address.

  • By default, Read-write permission is set to Private Read and Write for the VOD bucket. This ensures the security of your VOD resources. You can configure this parameter based on your business requirements.

  Buckets are provided by OSS. For more information, see What is OSS?

  The following table describes the values of the Read-write permission parameter.

  Value	Permissions
  Private Read and Write	Only the bucket owner and authorized RAM users can read, write, and delete the objects in the bucket. Other users cannot access the objects in the bucket without authorization.
  Public Read and Private Write	Only the bucket owner and authorized RAM users can write and delete the objects in the bucket. Everyone (including anonymous users) can read the objects in the bucket. Warning All users can access objects in the bucket over the Internet. This may result in data leaks and unexpectedly high costs. Exercise caution when you set Read-write permission to this value.

• In the Origin Domain Name section, specify the default origin domain name.

  If multiple origin domain names point to the bucket, click Set as Default next to one of the domain names. Then, playback callbacks are sent to the default domain.

  For information about how to configure origin domain names, see Domain management.
