The object of a backup procedure is to ensure that you can restore any data which has been lost.
For a backup procedure to fulfil this role, you need to save any and all data that has been changed during the day.
This is painstaking and repetitive work and consequently it is all too rare for it to be performed every day.
To make your life easier, the Eurobackup service performs all the operations involved in backing up data automatically.
The data can then be saved each time they are changed without involving any work on your part.
