As the local disk Ark service needs to be taken offline, subsequent support for the local disk Ark will not be provided. Existing local disk Ark services will be upgraded to Cloud Disk Snapshot Services.
The upgrade includes the following:
【Local Disk】is upgraded to 【SSD Cloud Disk】 The Ark service of the local disk is upgraded to the Snapshot service of the cloud disk. Billing related:
- The original Ark service will be closed, the Data Ark function will be returned, and the new Snapshot service will be opened.
- This is a smooth upgrade, maintaining the original price unchanged, and the service has been upgraded.
Compared with the local disk Ark, the Cloud Disk Snapshot service provides a longer backup time at the same price.
Upgrade Advantages:
- No IO contention, with three replica disaster recovery capabilities, IO isolation and data rapid migration capabilities
- Local disks do not support expansion, cloud disks support expansion
- Moving will not cause automatic backup interruption and has the ability to recover to the original local disk backup time point
- Backup strategy service has been fully upgraded
- Local disk Ark service: Enable disk continuous data protection function, auto backup strategy is 12 hours arbitrary second-level backup, 24 hours arbitrary hour-level backup, and 3 days arbitrary zero point backup
- Cloud Disk Snapshot Service: Opened the【Base】package, automatic backup strategy is 24 hours random second level backup, 60 hours random hour level backup, 15 days random zero point backup, supporting 3 manual backup snapshots
- After the upgrade is complete, you can modify the policy of your upgraded Snapshot service in the【Basic Information】card on the【Snapshot Service Management】->【Snapshot Detail Page】, catering to your various business needs
