Application Backup
Many database applications open their data files and leave the on-disk versions in an open, temporary, or inconsistent state until either the application synchronizes unwritten (cached) data, closes and saves the data file in use, or performs specific internal backup procedures. Similar situations can occur with applications that open and share data across a network; network-attached nodes will often cache data and not necessarily update the on-disk version until a later time. If you have backed up data from an application that was open and/or shared on the network, those files may not be usable on restore. To guarantee data consistency, it is good practice to perform cold backups or to ensure the corresponding jobs have appropriate pre-scripts. Pre-Scripts and Post-Scripts. A cold backup is a backup of any application data where the application has been closed down properly and its data backed up when the application is offline.
