How far back can I recover data from?

The ability to recover data depends on several factors, including the type of storage device, the file system used, and whether the data has been overwritten. Generally, deleted files can often be recovered for days, weeks, or even months using specialized software, as long as the data hasn't been overwritten. However, for more permanent deletion methods (like secure wiping), recovery may be impossible. Always consider regular backups to ensure data can be restored when needed.
