For On Demand synchronization, only the metadata is downloaded during sync and packages are fetched and stored on the filesystem when clients request them. For Background synchronization, a background task will download all packages after the initial sync. The Immediate option will download all metadata and packages immediately during the sync.
Selecting this option will result in contents that are no longer part of the upstream repository being removed during synchronization.
For older operating systems such as Red Hat Enterprise Linux 5 or CentOS 5 it is recommended to use sha1.
