How Long Does VBS Take to Back Up an EVS Disk? The initial backup of an EVS disk is a full backup and subsequent backup operations are all incremental backups. The initial backup takes a long time whereas subsequent incremental operations are much shorter.
What Are the Differences Between OBS, EVS, and SFS? Table 1 compares OBS, EVS, and SFS.
Why Was a 40-GB EVS Disk Added to the Target Server During the Migration? SMS creates and attaches a 40-GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use basis.
Possible Causes for No Resource Optimization Recommendations If you have enabled OA but have not received any EIP, ELB, or EVS resource optimization recommendations for a long time, the possible causes are as follows: There are no idle EIP, ELB, or EVS resources.
How Do I Know Whether EVS Disks Are Available in a Flavor? Some BMSs do not support EVS disks because the BMSs do not have SDI iNICs or for other reasons. Therefore, certain flavors with EVS disks unavailable are provided for creating such BMSs.
Does CSBS Support Backing Up All EVS Disks on an ECS? Yes. CSBS supports backup and restoration of all EVS disks as a whole instead of part of the EVS disks on an ECS. Parent topic: About Backup

How Can I Use a Backup to Create an EVS Disk or ECS? You can use CSBS backups to create ECSs and use VBS backups to create EVS disks. CSBS backups cannot be directly used to create ECSs.
What Are the Differences Between SFS, OBS, and EVS? Table 1 shows the comparison between SFS, OBS, and EVS. Table 1 Comparison between SFS, OBS, and EVS Dimension SFS OBS EVS Concept SFS provides on-demand high-performance file storage, which can be shared by multiple ECSs.
Do I Need to Stop the Server Before Restoring EVS Disk Data with a VBS Backup? Yes. Before restoring the EVS disk data using a VBS backup, you must stop the server to which the EVS disk is attached, and detach the EVS disk from the server.

Disk Capacity Expansion of an EVS Cluster Context As customer services evolve, disk space often becomes the initial bottleneck. In scenarios where other resources are ample, the conventional scale-out process is not only time-consuming but also resource-inefficient.
Figure 6 Attaching an EVS disk (before the BMS restart) Figure 7 Attaching an EVS disk (after the BMS restart) Figure 8 Detaching an EVS disk (before the BMS restart) Figure 9 Detaching an EVS disk (after the BMS restart) To identify EVS disks, log in to the BMS and run the lsscsi
Attaching an EVS Disk to a BMS (Deprecated) Function This API is used to attach an EVS disk to a BMS. This API has been deprecated. Use the API in Attaching an EVS Disk to a BMS. Constraints A bootable disk cannot be attached to a BMS.
Elastic Volume Service Disks 02:20 Delete a single EVS disk and delete EVS disks in a batch
Can I Attach an EVS Disk Purchased with a Yearly/Monthly Server to Another Yearly/Monthly Server? No. A yearly/monthly disk purchased together with a yearly/monthly server is in a binding relationship with the server. It cannot be attached to other servers.
When the Status is Available, the backup job of the associated EVS disks is complete. Disassociating EVS disks In the list of associated EVS disks, locate the EVS disk to be disassociated from the backup policy and click Disassociate in the Operation column.
After the modification, format the EVS disk.
