By saving your work frequently, you can ensure a minimum of lost data if your system fails for any reason. If a problem occurs, you can restore a drawing backup file.

In the Application tab (Application Preferences dialog box), you can specify that backup files are created when you save drawings. If you do, each time you save a drawing, the previous version of your drawing is saved to a file with the same name and a .bak file extension. The backup file is located in the same folder as the drawing file. You can revert to your backup version by renaming the .bak file in Finder to a file with a .dwg extension. You may want to copy it to a different folder to avoid overwriting your original file. Some more details about this field  of autocad course in islamabad are as under.

If you turn the automatic save option on, your drawing is saved at specified time intervals. By default, files saved automatically are temporarily assigned the name filename_a_b_nnnn.sv$.

 Filename is the current drawing name,  a is the number of open instances of the same drawing file in the same work session, b is the number of open instances of the same drawing in different work sessions,  nnnn is a random number.

These temporary files are automatically deleted when a drawing closes normally. In the event of a program failure or a power failure, these files are not deleted. To recover a previous version of your drawing from the automatically saved file, rename the file using a .dwg extension in place of the .sv$ extension before you close the program.
