Does that include data contained in their x years of backups?

  What companies keep x years of backups (for any x > 1, possibly even ½)? I don’t think that’s worth much to any company. Better make sure your recent backups are good than spend effort on keeping such old backups around. For accounting/tax purposes, you need data up to typically 7-ish years ago, but isn’t that data typically online nowadays so that it will end up in today’s backup? Even if they still have the bits from an old backup, they should have thrown away its encryption key.

  Yes, so it's important to distinguish between backups and archives. If you're keeping data for years, it's an archive and not a backup.
