You can restore backups to get your P11D data back to a prior point.

For example, this is useful if you need to undo some changes you've made, or if you're moving to another computer.

When you restore a backup, enter your username and password from the time you created the backup.

If you changed these credentials after you took the backup, use the old details from when you took the backup.

1. Go to File, then select Restore.
2. Select Next, then Browse.
3. Browse to the backup file you want to restore and select it.
4. Select Open then Next.
5. Choose the type of files to restore, for example, Data Files, then select Next.
6. Select Finish.
7. Enter your user name and password, then select Login.
