Yes, you can use a snapshot created from a system disk to create a new cloud disk. A snapshot is a point-in-time copy of your disk data, and it can be used to restore or create new disks.
For example, if you have a system disk snapshot taken during a stable state of your virtual machine, you can use that snapshot to create a new cloud disk. This new disk can then be attached to another instance for testing, recovery, or migration purposes.
In Tencent Cloud, you can use the Snapshot service to create a snapshot of your system disk and later use the Cloud Block Storage (CBS) service to create a new disk from that snapshot. This is useful for backup, disaster recovery, or cloning environments.
