A split database is created by splitting two database files ending up with a ‘Back-End’ and ‘Front-End’ database files. A ‘Back-End’ database normally contains only the data tables while the ‘Front-End’ comprises the remaining database objects such as queries, forms, and reports. The data that a user inputs in a database object will be stored in the tables that back-end databases hold. Anybody can go through the information available in the front-end database but in order to access the back-end, the user needs to have administrator permission. Splitting a database can improve its performance, help secure your data, and enables greater availability. Since both databases have diverse properties, they are also backed up self-sufficiently. Front-end databases, which containminor types of data, use up less space. Because of that, it takes a smaller amount of time to create the backups. But that’s the not the case with back-end databases as they hold all the data. For that reason, it is imperative to generate regular backups to avoid incidents of corrupted Access databases.
Creating a backup for Back-end Databases • Before generating the backup, make sure to inform all users on the system about it. Creating a backup requires exclusive access to all the database files. This process restricts users from using the database. • Here are the steps in creating a Back-end database backup. • Start Access. • Click Open Other Files.
3. Click Browse. • 4. Select the back-end database file that you want to back up. • 5. Click the arrow next to Open. • 6. Click Open Exclusive.
7. Click File and select Save As. • 8. Under File Types, click Save Database As. • 9. Under Advanced, click Back Up Database. • 10. In the Save As dialog box, review the name of your database backup and select a location in which to save your backup. • 11. Click the Save button.
Creating a backup for Front-end Databases • Since the front-end database is available to most users in an organisation, they all have a separate copy of that database. Users may modify and restructure their copy according to their needs. The changes made by a user to his own copy of the front-end database will only be visible to him/her. • Every user needs to generate a backup of the front-end database especially if he wants to see the customised arbitrary design changes in the front-end database. • Here are the steps in creating a Front-end database backup. • Once you’re done making the necessary changes, click the File tab. • Then, click Save As. • Under File Types, click Save Database As. • Under Advanced, click Back Up Database. • In the Save As dialog box, review the name of your database backup and select a location in which to save your backup. • Click the Save button.
