Explanation
Snapshot is the backup utility that captures the most information and tends to create the largest archives.
Snapshot creates an image of the entire system, including operating system files, configuration files, databases, and logs. It can be used to restore the system in case of a failure or corruption. Backup creates a compressed file that contains configuration files and databases, but not operating system files or logs. It can be used to restore configuration settings and policies. Database Revision creates a backup of only the database files that store policies and objects. It can be used to revert to a previous revision of the database. Migrate export creates a compressed file that contains configuration files, databases, and logs, but not operating system files. It can be used to migrate data from one machine to another with different hardware or software versions.References:
