Object Storage Service:Batch operations in OSS

You can use the following methods to upload multiple objects at a time:

• ossimport

  Use ossimport to migrate data to OSS from data sources, such as local servers, OSS, and third-party cloud storage services like Amazon Simple Storage Service (Amazon S3), Azure Blob, and Tencent Cloud Object Storage (COS). ossimport is especially suitable for the migration of large amounts of data. For more information, see Overview.

• ossutil

  Use the cp command with the -r (--recursive) option to upload objects to OSS in batches. For more information, see Upload objects in batches by using ossutil.

• ossbrowser

  Use ossbrowser to select multiple objects and upload them to OSS. For more information, see Common operations.

• OSS console

  Upload multiple objects to OSS at a time by using the OSS console. For more information, see Simple upload.

• ZIP package decompression

  Configure decompression rules, compress multiple local files into a ZIP package, and then upload the ZIP package to OSS. Then, Function Compute is triggered to decompress the ZIP package and upload the decompressed files to OSS. For more information, see ZIP package decompression.

You can use the following methods to download multiple objects at a time:

• ossutil

  Use the cp command of ossutil with the -r (--recursive) option to download all objects from a specified directory to your local machine. For more information, see Download objects in batches by using ossutil.

• ossbrowser

  Use ossbrowser to select multiple objects or directories and download them to your local device. For more information, see Common operations.

• OSS console

  Use the OSS console to select multiple objects and download them to your local device. For more information, see Simple download.

• Package and download objects

  Use Function Compute to package multiple objects into a single archive for local download. For more information, see Package multiple objects into a ZIP archive for download.

You can use the following methods to copy multiple objects at a time:

• CRR

  Use cross-region replication (CRR) to replicate objects whose names contain a specific prefix at a time. You can choose whether to synchronize historical data and whether to synchronize deletion operations. For more information, see CRR within the same account.

• ossutil

  Use the cp command with the -r (--recursive) option to copy objects in a specified directory to another directory, or to another bucket in the same account. For more information, see Copy objects in batches by using ossutil.

• ossbrowser

  Use ossbrowser to select multiple objects or directories and copy them to another directory or another bucket under the same account. For more information, see Common operations.

You can use the following methods to delete multiple objects at a time:

• OSS SDK

  Use SDKs to delete multiple objects at a time.

  • OSS SDK for Java

  • OSS SDK for Python

  • OSS SDK for Go

  • OSS SDK for C++

  For examples of deleting objects by using OSS SDKs for other programming languages, see Overview.

• OSS API

  Call the DeleteMultipleObjects operation to delete multiple objects at a time. For more information, see DeleteMultipleObjects.

• ossutil

  Use the rm command of ossutil with the -r (--recursive) option to delete all objects that match a specified prefix. For more information, see Delete objects in batches by using ossutil.

• ossbrowser

  Use ossbrowser to select and delete multiple objects or directories at once. For more information, see Common operations.

• OSS console

  • Select and delete multiple objects in the OSS console. For more information, see Delete objects.

    You can also delete an entire directory, which removes all objects within it.

  • Use the Delete parts feature in the OSS console to delete incomplete multipart upload parts in batches. For more information, see Delete parts.

• lifecycle rule

  Configure a lifecycle rule to automatically delete objects in batches. For more information, see Lifecycle rules based on last modified time.

You can use the following methods to change the storage classes of multiple objects at a time:

• ossutil

  Use the set-props command with the --storage-class and -r (--recursive) options to change the storage class of specified objects in batches. For more information, see set-props (Set object properties).

• Lifecycle rules

  Configure lifecycle rules to automatically change the storage classes of multiple objects at a time. For more information, see Lifecycle rules based on the last modified time.

You can use ossutil to change the ACLs of multiple objects at a time.

• Use the set-props command of ossutil with the --acl and -r (--recursive) options to change the ACL for multiple objects. For more information, see set-props (Set object properties).

You can use the following methods to restore multiple Archive and Cold Archive objects at a time:

• ossutil

  Use the restore command with the -r (--recursive) option to restore multiple frozen objects at once. For more information, see Restore objects in batches by using ossutil.

• ossbrowser

  Use ossbrowser to select objects that you want to restore and restore them at a time.

You can use the following methods to modify the metadata of multiple objects at a time:

• ossutil

  Use the set-props command of ossutil with the --metadata and -r (--recursive) options to modify the metadata for multiple objects. For more information, see set-props (Set object properties).

• OSS console

  Change the metadata of multiple objects at a time by modifying the HTTP headers of the objects in the OSS console. For more information, see Manage object metadata.
