Creating a Snapshot¶
Scenarios¶
You can create an EVS snapshot on the management console to save the EVS disk data at a specific time point.
Note
Creating snapshots does not affect the performance of the disk.
Constraints¶
A maximum of 7 snapshots can be created for one disk.
Snapshots can be created for both system disks and data disks.
Snapshots can be created only for available or in-use disks.
Snapshots of encrypted disks are stored encrypted, and those of non-encrypted disks are stored non-encrypted.
If a disk is created from a snapshot, the AZ of the disk is the same as that of the snapshot's source disk and cannot be changed.
