What are the key characteristics of vsanSparse snapshots and what are the requirements for their implementation?
The three true statements regarding vsanSparse snapshots are A, D, and F. vsanSparse snapshots require at least vSAN 6.0 to function, they operate in an always-sparse format, and they support on-disk formats of version 1 or higher.
Key Characteristics of vsanSparse Snapshots:
1. vSAN 6.0 or Higher Requirement: vsanSparse snapshots require a minimum vSAN 6.0 version or higher to be supported. This means that to utilize this snapshot feature, the vSAN environment must be running on vSAN 6.0 or a newer version.
2. Always-Sparse Format: Unlike traditional VMFS snapshots, vsanSparse snapshots operate in an always-sparse format. This means that the snapshots only consume physical storage space needed for the changes made to the virtual machine after the snapshot is created. This efficient use of storage helps in optimizing storage capacity.
3. On-Disk Format Compatibility: vsanSparse snapshots are supported if the on-disk format is v1 or higher. This compatibility provides flexibility in using the vsanSparse snapshot feature with different on-disk formats, ensuring seamless integration with vSAN datastores.
In conclusion, vsanSparse snapshots have specific requirements and characteristics that set them apart from traditional snapshots. By understanding these key features, users can effectively leverage vsanSparse snapshots in their vSAN environments for efficient storage management and data protection.
