归档层数据传输
Outdated backup files from the capacity tier can be moved to the archive tier. After that, the transported files are deleted from the capacity tier. They can stay in the performance tier or be deleted from there depending on the data transfer policy of the scale-out backup repository:
- In case the copy policy is selected (the outdated backup files are copied from the performance tier to the capacity tier), the original file stays in the performance tier.
- In case the move policy is selected (the outdated backup files are transferred from the performance tier to the capacity tier), the original file disappears from the performance tier.
Data transfer policy | Performance tier | Capacity tier | Archive tier |
|---|---|---|---|
Copy | Original file | (nothing) | Copy of the file |
Move | (nothing) | (nothing) | The transferred file |
Proxy Appliances
Data transfer from the capacity extent to the archive extent is done through proxy appliances — temporary virtual machines. The template for all the proxy appliances is set up at the Proxy Appliance step of the Adding Amazon S3 Glacier or Adding Azure Archive Storage wizard.
You can set up the size of the virtual machine and cloud resources where the proxy appliance will be created. You can specify the proxy appliance settings manually, or use the default settings.
After the archiving job is finished, all the proxy appliances are automatically deleted. If the job ends prematurely, the proxy appliances will be deleted as well. Also, any proxy appliance can be deleted if there are no more tasks for it.
