What do you mean "by the routine way"? By auto-backup?
Anyway, you can find the back-up apps in Settings-> Additionnal or extra settings ->and at the bottom "Backup and reset".
The backup is save in SD Card so you can move it. But I don't know if backups from Mi2 to Mi4 are compatible.
Is it what you need?
