From your daily backup.

If you can't find your backup, there are companies that specialize in retrieving data ----------- for a big pile of cash money.

Intuit doesnt keep backups of your client data, thats all on you. 

When you say "crash" that could mean lots of things, you'll want to take it to a computer tech to see if they can get into the harddrive and copy the ProSeries data folders so you can put them into the new computer.

Only from your backups, the ones you do regularly.
