Prefs - Backup
Auto Backup to FLW
If you want to create automatic backup copies of a project's current state this option has to be activated. It is strongly advised to use automatic backups, because due to its complexity, RealFlow may become unstable under certain circumstances. To prevent a loss of data, “Auto Backup” is highly recommended. Please note that only the FLW file is copied, not the simulation or data files.
Auto Backup to XML
Instead of writing the entire scene with all data, it is also possible to save only the nodes with all their settings and properties. The XML format provides a very convenient way to prevent data loss, because XML files have some clear advantages in comparison to the first method:
Saving time for XML files is almost zero, even with the most complex scenes.
The size of the generated files is much smaller than with the FLW format.
XML files are not affected by version incompatibilities.
XML files are more reliable and can be read/edited with any text editor.
Mode
This option can be used to either write backups within a timeframe per minute or frame. Very large files need some time to be written and can slow RealFlow down, especially when you have to work in a network.
Every
“Every” is related to “Mode”. It indicates the time period that will pass until the backup file is written, for example each 10 seconds or frames.
Number of Files
Here you can determine the number of backup files written to disk within the specified timeframe. You should store at least two files.
