If you have shutdown Samba on the DC, you don't need the backup-script.
This script just create hot-backups, so you don't have to shutdown a DC
for backup. If Samba is already stopped, then it's save to backup/copy
the files.

If you have brought the new DC1 together with DC2 and the replication
has started, you can't go back to the old DC1, if something doesn't
work. Then you will get an inconsistent AD.

If you want to test this before, then do this in a separated
installation and not in production. Then you're save from any horrific
consequences. Not if you do this in with other production
DCs/workstations. Even if you've turned most computers off, you don't
know what the others change in the meantime in AD (eg. machine password
changes). If you roll-back, you can run into problems.

Use a test installation and don't test in production.
