In a complete data backup, all
data devspaces are backed up to the backup medium you specified. In an incremental data backup it is only the pages which have been updated that are backed up.You can carry out the following types of backups:
Data Backups in WARM Mode
In
WARM mode, you can either perform complete or incremental data backups with or without checkpoint.When you back up in warm mode, remember that the state of the
database instance that is saved is always the state when the backup operation was started.When you carry out a data backup with checkpoint, you get a
consistent data backup.Data Backups in COLD Mode
Complete and incremental data backups (without Checkpoint) can also be carried out when the database is not running, that is in COLD mode.
Whether you get a
consistent data backup in this case depends on how the database instance was shut down. If a checkpoint was requested on shutdown, and this could be performed correctly, you can generate a consistent data backup.See also:
