Bucket

Feature	Description	Supported or not	Remarks
Storage type	TOS offers a variety of storage types, including Standard Storage, Infrequent Access Storage, Archive, Cold Archive, and Deep Cold Archive. These options cover a wide range of data storage needs, from hot to cold.	✅	For buckets with hierarchical namespace enabled, check the console to see if multi-AZ redundancy is available.
Lifecycle rules	With the lifecycle feature, you can configure rules to periodically move objects between storage types or delete expired objects, such as cold data stored in Archive or Deep Cold Archive.	✅	You cannot use lifecycle rules to transition a directory because directories only support Standard Storage. Once a directory meets the expiration condition, TOS will only delete it after all of its subdirectories and objects have been deleted. Lifecycle rules do not support deleting non-empty directories. The expiration of a directory is determined by its creation time rather than its last modified time.
Hosting a static website	You can use TOS to host a static website. First, store all contents of the website in a TOS bucket. Next, configure rules to host the website so that it can be accessed via the bucket's domain name.	✅	-
Back-to-origin rules	You can set up a back-to-origin rule to retrieve missing objects from the specified origin server directly whenever they are requested from your bucket.	✅	-
Event notification	TOS can deliver notifications for certain event changes to Volcano Engine Function as a Service (veFaaS). This feature helps you monitor resource changes in real time.	✅	The following events are supported by event notifications on HNS buckets: tos:ObjectCreated:Put tos:ObjectCreated:Post tos:ObjectCreated:Copy tos:ObjectCreated:CompleteUpload tos:ObjectCreated:Modify tos:ObjectRemoved:Delete tos:ObjectRemoved:TrashMoved tos:LifecycleExpiration:Delete tos:LifecycleExpiration:TrashMoved tos:ObjectRestore:Post tos:ObjectRestore:Completed tos:LifecycleTransition tos:ObjectRename
Bucket tag	Tags help you categorize buckets by purpose, type, owner, environment or other criteria, making managing cloud resources easier.	✅	-
Bucket inventory	You can use the bucket inventory feature to create inventory lists on a schedule that you define, for either a given bucket, or objects that share a prefix. Inventory lists include object size, storage type, and last update date.	✅	Exporting replication status or encryption status of objects in HNS buckets is not supported. The first inventory file will be delivered within 48 hours when you create a bucket inventory rule for the first time.
Batch processing	With the batch processing feature, you can perform certain operations on multiple objects in a bucket. For example, you can copy data in bulk or replace access control lists (ACLs) for objects in bulk.	❌	-
RenameObject	TOS lets you rename objects using the RenameObject feature.	✅	The settings for HNS and FNS buckets differ. For more information, see Supported APIs (HNS buckets).
Bucket policy	Bucket policies are strategies that apply to individual buckets and their associated resources. You can use them to grant other users permission to access the corresponding resources.	✅	-
IAM policy	Volcano Engine offers Identity and Access Management (IAM), a system that controls access to cloud resources for different identities. Through IAM policies, you can assign permissions to IAM users for the corresponding resources.	✅	-
Bucket ACL	An ACL is a mechanism for managing read and write access based on user accounts, where the bucket or object owner has full control over the resource. You can grant an Identity and Access Management (IAM) master account read and write permissions for the current bucket and its ACL. Then, the grantee can access the bucket using the access key ID (AK) and secret access key (SK).	✅	-
Object ACL	An ACL is a mechanism for managing read and write access based on user accounts, where the bucket or object owner has full control over the resource. You can use the TOS console to set ACL permissions for an object.	✅	-
CORS rules	You can use cross-origin resource sharing (CORS) rules to secure data transfers across domains (origins). When TOS receives a CORS or OPTIONS request, it reads the CORS rules of the bucket, performs permission checks, and returns the appropriate headers.	✅	-
Custom domain	If you wish to use your own domain name to access objects stored in TOS, you can associate your custom domain with the bucket. After association, you can use the corresponding domain name to access your objects.	✅	-
Cross-region replication	You can use cross-region replication to automatically copy objects from one bucket to another in different regions. This feature lets you filter which objects are replicated and monitor their progress.	❌	-
Same-region replication	You can use same-region replication to automatically copy objects across buckets in the same region. This feature lets you filter which objects are replicated and monitor their progress.	❌	-
Versioning	You can use the versioning feature to keep multiple versions of objects in your bucket so that you can restore objects that are accidentally deleted.	❌	-
Multi-AZ redundancy	With multi-AZ redundancy, you can store data across multiple availability zones in the same region. This ensures that your storage service will be stable even if one zone fails.	✔️	Only the China (Beijing) region supports multi-AZ redundancy for HNS buckets.
Image style	An image style is a template that contains multiple image processing parameters such as format conversion and progressive display. You can use an image style to process multiple images uniformly, thereby simplifying operations.	❌	-
Original image protection	Original image protection is a security feature that prevents unauthorized access to images by anonymous users.	❌	-
Usage statistics	The TOS console offers a comprehensive overview of your bucket, providing insights into storage usage, transferred data volume, request counts, and other basic data.	❌	-
Logging	You can retrieve and analyze access logs generated during your interactions with TOS through Torch Log Service.	❌	-
Storage Lens	Storage Lens is an analytics feature that provides insight into TOS resource usage and activity. You can use it to generate summary insights, such as total storage usage, the total number of objects, and bytes of historical object versions or incomplete multipart uploads.	✅	-
Upload callbacks	An upload callback is a process in which the client includes callback parameters in its upload request. Once the upload is complete, the TOS server sends a synchronous POST request with the parameters to the specified third-party application server. The client only receives the results once the application server acknowledges the request and sends a response.	❌	-
Server-side encryption	With server-side encryption, TOS encrypts your uploaded data before storing it. When you download these objects, TOS automatically decrypts the data and sends it back to you.	❌	-
Double-gated access control	You can set up double-gated access control over your bucket resources by configuring VPC endpoint and bucket policies. This allows you to restrict access to specific resources within a private network and to specific VPCs simultaneously.	❌	-
Security configurations	Security configurations control the prompt level for dangerous operations. At a high level, deleting data requires manual confirmation, effectively reducing accidental operations.	❌	-
Image processing	TOS allows you to process image files stored within it. You can initiate image processing by including the appropriate parameters in requests made through the GetObject API. Supported features include resizing, cropping, and watermarking images.	❌	-
Video processing	TOS allows you to process video files stored within it. You can initiate video processing by including the appropriate parameters in requests made through the GetObject API. Supported features include extracting video frames and retrieving video metadata.	❌	-
Single-region access points	A TOS single-region access point is an endpoint that can be configured with independent permissions. It provides a dedicated domain name for a bucket. You can create multiple access points for the same bucket. This enables you to tailor access control and access methods for different businesses or user groups.	✅	-
TOS accelerator	TOS offers an accelerator feature at the availability zone level that stores frequently accessed objects on NVMe SSDs, a high-performance storage medium. This feature provides quick responses with millisecond-level latency and high data transfer rates for demanding business workloads.	✅	-

Object

Feature	Description	Supported or not
Uploading objects	You can upload local files to your bucket through the TOS console.	✅
Downloading objects	You can download objects from your bucket to your computer through the TOS console.	✅
Viewing object details	You can view object details in the TOS console, including filename, size, URL, and storage type. You can also perform other operations, such as changing the number of objects displayed per page, copying object paths, sorting objects, and searching for objects.	✅
Sharing objects	After uploading files or folders to TOS, you can share them with other users via a URL.	✅
Renaming objects	You can rename objects in a bucket through the TOS console.	✅
Copying objects	You can use the TOS console to copy files or folders to different locations.	✅
Moving objects	You can use the TOS console to move files or folders to different locations.	✅
Managing object tags	TOS lets you tag objects and manage their lifecycles based on those tags.	✅
Managing object metadata	Object metadata consists of key-value pairs that describe an object's properties. You can customize an object's metadata.	✅
Editing object permissions	All objects uploaded to a bucket automatically inherit its access permissions (ACL). You can modify the access permissions of individual objects on the Objects page.	✅
Changing object storage type	TOS supports multiple storage types. You can change the storage type of your objects via the console.	❌
Deleting objects	You can delete an object that is no longer needed to save storage space and cost.	✅
Managing parts	When you use multipart upload for large objects, the objects are divided into parts for uploading and then merged. Any unmerged parts are stored in the parts list. You can view and delete parts in the parts list.	✅
Creating folders	TOS lets you create folders to organize files.	✅
Deleting folders	You can delete any folders that are no longer needed. Deleting a folder will also delete its contents.	✅
Restoring objects	If the object you want to access is stored in Archive, Cold Archive, or Deep Cold Archive, restore it first.	✅
Task center	After submitting a task to upload, copy, move, or restore objects, or to delete directories or parts, you can view and manage the task status at the task center.	✅
