Point In Time Copies (Snapshots)

  • Albrecht ScribaEmail author


Several tasks, like backups or lengthy data analysis jobs, require a frozen image of the application data while the application remains online and produces new data. For instance, reporting needs a stable state of information to generate coherent and usable data. A data copy must be sent to a testing data center with a specified time stamp. Or, as another example, you could wish to create backup images that require a reduced amount of recovery complexity after a restore operation (see notes below).
