The Save / Updated Pages menu function creates an incremental backup version of the local serverdb's data devspace. This backup version contains all pages updated since the last Save / Data or Save / Updated Pages.
For backups in WARM mode, it must be taken into account that the database is saved with the state when the backup operation was started. Modifications to the contents of the database made during the backup operation are not saved.
Save / Updated Pages can also be executed in COLD mode. To be able to create a consistent database with the generated backup version without having to restore more log devspaces during a subsequent Restore, the database must be in a consistent state when saving. A database is in a consistent state, when it was switched into COLD mode using the Operating / Shutdown ~/ Cold Ok (not Quick) menu function.
Incremental backups are only advantageous when the database modifications concentrate on partial database devspaces. As a rule, backup times are quite short with Save / Log, but recovery may take more time.
As for the selected parallel media, Save / Updated Pages behaves like Save / Data.
