Create and Restore Backup Files
Backup files help ensure the safety of your drawing data. If a problem occurs,
you can restore a drawing backup file.
Computer hardware problems, power failures or surges, user mistakes, or
software problems can cause errors in a drawing. 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.
Use Backup Files
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.
Save Your Drawing Automatically at Specified Intervals
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.
