Is there an autosave feature in Adobe Illustrator?

I found this pretty useful technique using the “actions” panel to autosave.

In case that link ever goes down, the basic idea is to create an action set ‘Autosave’ containing two actions, which each trigger each other, creating an infinite loop.

Then, in one action, add a ‘Save as’ saving to a file you can use as a recovery file, placed somewhere logical, as well as a pause in each one for half the amount of time you want to leave between saves.

If you want a longer pause than the maximum 100 seconds, put a pause in both actions, saving every 200 seconds – just over 3 minutes. If you want longer (e.g. every 5 minutes), add an extra action to the loop with another pause.
