This document describes how to start a migration task.
Step 1. Create a migration task
2. Click Create migration job.
Your account needs to be added to the allowlist before you can use this feature. If you need it, submit a ticket for application.
Step 2. Select the region for migration
Select the destination CFS region as the region for migration.
Step 3. Select the source service provider
Select Tencent Cloud COS.
Step 4. Select the migration method
Currently, bucket migration and inventory migration are supported:
Bucket migration: It is suitable for migrating an object storage bucket or all objects in a certain directory.
Inventory migration: It is suitable for migrating objects within a specified time period. Currently, you can export the objects modified after a time point or within a time period through the object storage inventory for filtered data migration.
Step 5. Select the overwriting method
Currently, overwriting by last modified time, full overwriting, and no overwriting are supported.
Overwriting by last modified time: When files with the same name exist, their
LastModified values are checked, i.e., last modified time.
LastModified value of the file in the source address is earlier than that of the file in the destination address, no overwriting is performed.
LastModified value of the file in the source address is later than that of the file in the destination address, overwriting is performed.
If the two files have the same
LastModified value, further check:
Size values are different, overwriting is performed.
Size values are the same, no overwriting is performed.
Full overwriting: Files with the same name are overwritten without any check.
No overwriting: In contrast to full overwriting, this method means no overwriting of files with the same name without any check.
Step 6. Enter the
SecretKey required by access to object storage, which are encrypted on the platform. If you use a temporary key, make sure that the migration task can be completed during the validity period of the key; otherwise, part of the migration will fail.
Step 7. Enter the source information (required for bucket migration only)
Currently, you can either select a bucket or enter the source bucket address (object storage endpoint) in the console. For data transfer from the root path, make sure that the source path is empty. For data transfer from a subpath, the source path should end with "/".
Step 8. Enter the inventory URL (required for inventory migration only)
Enter the URL of the
manifest.json file of the object storage inventory. Specifically, after an inventory is generated, find the URL of the
manifest.json file and enter it as the inventory URL.
Step 9. Select the destination file system
Select the destination file system and path. For data migration from the root path, leave the destination path empty. If the migration is from the
test directory, enter either
