Have done just this.
A customer of mine got hit by the ACCDFISA v2.0 ransomware on Saturday, they didn't realise til they got back on Monday. Business was down for all of Monday before they decided to pay the £3750 ransom. A day later we got the decrypter though and the following day they were back in action.
They didn't have regular backups in place so this was their only option. If they'd remained closed any longer they would have started losing customers and may not have survived.
It sucks, but what ya gonna do.
They learnt an expensive but valuable lesson.
