What Are the Snapshots of a Target Server Used for?
SMS creates the following types of snapshots for each target server disk:
- Cutover snapshots: After a migration is complete, SMS creates a snapshot for each target server disk before the service cutover. These snapshots are used for rollback if any service faults happen. Old snapshots are deleted and new snapshots are created automatically whenever the target server is launched again.
It is recommended that these snapshots are deleted after your services are running smoothly on the target server.
- Synchronization snapshots: For a Windows server migration or Linux block-level migration, after the source data is migrated and synchronized and before the target server is launched, SMS creates a snapshot for each target server disk to ensure data consistency between the source and target.
- Clone snapshot: When you clone a target server, SMS creates a snapshot for each target server disk. These snapshots are used to clone the target server and put the migration status back to continuous synchronization after the clone is complete.
