A full backup involves copying all the data from one server to another location. It provides the most comprehensive backup but can be time-consuming and resource intensive.
Incremental backups only copy the data that has changed since the last backup, whether it's a full back up or another incremental backup.
Differential backups copy all the data that has changed since the last full backup. Unlike incremental backups, which only consider changes since the last backup (whether full or incremental), differentials always compare to the last full backup.
Cloud backup involves storing server data in a cloud-based service. It provides off-site storage, which can be crucial for disaster recovery and data protection.
Offsite backup stores backups in a physically separate location from the primary server. It protects against physical disasters affecting the primary server location.
