Automatic backup strategy

Home

4D v15.4

4D provides a default backup strategy when a database is created. This strategy puts into place a set of backup parameters that assure minimum database security.

These settings can be changed once the database is created.

The backup strategy is enabled, by default, when a new database is created. To disable it, simply deselect the Enable the automatic backup strategy for every new database option on the General Page of the Preferences dialog box.

The automatic backup strategy includes the following settings:

Automatic backup every Sunday at 00:00:00.
Backup of all database files (data, log, structure and user structure) next to the database structure file.
Creation and activation of a log file (named DataFileName.journal).
Keeping of last 3 backups, standard archive, etc.
Automatic integration of last log file when opening if database is incomplete.

Of course, it is also possible to change these settings after the database has been created.
