The fully-managed migration into and out of public network requires no Agent and automatically executes new tasks. Migration Service Platform (MSP) saves the URL data obtained through public network to Tencent Cloud Object Storage (Tencent Cloud COS). However, this incurs CDN traffic fees to source vendor. For specific fees, refer to the pricing of the source vendor.
The following section describes how to use the URL list method to configure a fully-managed public network migration task and implement data migration.
You can use MSP with your root account. However, for security reasons, we recommend you create a sub-user, use the sub-user’s API key for migration, and delete the sub-user after migration.
Task Name: You may enter a string of 1-60 characters, including Chinese characters, English letters, 0-9, backslashes (), underscores (_) or hyphens (-). This name will be displayed in the task list, and you can check the status and progress of the migration.
3. Set the file source to be migrated.
Select URL list for ISP. You can upload the URL list files or provide the URL list file download address. For large URL list files, the browser upload may time out. We recommend you save the URL list file to COS, select Provide URL list file download address, and then enter the COS URL of this file. You need to place all URLs in a text file, with one URL per line.
For example, if you choose Provide URL list file download address and enter the file address http://xxx.xxx.xxx/url.txt
, which includes URLs http://xxx.xxx.xxx/xxx/l.jpg
and http://xxx.xxx.xxx/xxx/xxx/xxxxxx/test.mp4
, both files contained in URLs will be migrated in MSP.
4. Set the task execution time.
Data migration will occupy the network resources of the source vendor. You can set the start execution time of the migration task according to your business circumstances.
5. Set data migration execution speed.
You can set the upper limit of the migration speed to avoid the extra CDN bandwidth cost due to excessive migration speed. The actual migration speed will be lower than the set value due to network fluctuations.
6. Select the migration destination.
In the **Migration Destination Information, enter SecretId and SecretKey of the Tencent Cloud sub-user. Select the migration destination bucket by clicking Refresh next to the drop-down box.
7. Specify the storage path of the destination bucket.
/a.txt
and /dir/b.txt
in the source bucket, you enter dest in the text box. After migration, the two files will be found in /dest/a.txt
and /dest/dir/b.txt
of the destination bucket.dest/20180901
in the text box, and after migration, the two files will be found in /dest/20180901/a.txt
and /dest/20180901/dir/b.txt
of the destination bucket.
- If the files with the same name exist in both the migration source and destination, we recommend you select Skip (keep the file with the same name in the destination bucket) for File with the same name. By default, Overwrite (the file in the source bucket replaces the file with the same name in the destination bucket) is selected.
- If the file content is changed during migration, you need to migrate again.
- Select a migration mode.
-Create a migration task and start fully-managed migration immediately: select the managed migration mode. After you click **Create and Start”, MSP accesses and migrates the source files through public network.
You can check the status and progress of all migration tasks in the Object Storage Migration page.
The migration speed is determined by the lowest speed during each stage of the migration process and is affected by factors such as the network transmission speed and the maximum concurrency. The following table describes these factors:
Influencing factor | Description |
---|---|
Read speed of the migration source | The read speed of the data source varies depending on service providers. Generally, |
MSP transfer speed | The MSP provides a maximum migration bandwidth of 200 Mbps. |
Write speed of the migration destination | For Tencent Cloud COS, the write speed is 200 Mbps and the write concurrency ranges from 500 to 800. Generally, the migration speed ranges from 6 MByte to 25 MByte, that is, 21 GB/h to 87 GB/h. |
Data that is migrated by using the URL list uses standard storage on Tencent Cloud by default.
