Every major financial regulator has business continuity and disaster recovery requirements but the standards are woefully outdated. A plan that gets the bank back to full functionality within 24 hours would be acceptable to most regulators and even considered speedy to some.

Tangentially related, I highly recommend the movie "Out of the Clear Blue Sky." Cantor Fitzgerald was a bond trading firm at the top of one of the twin towers and lost every employee who was in the office on 9/11. Incredibly, despite losing the majority of their employees and despite losing almost all of their trading infrastructure, they managed to resume operations in time for the bond market's reopening 48 hours later.
