OK, what Tim pointed out is, when you run the samba-tool backup command, 
you are backing up the domain data, not an individual DC.

Whilst you have one working DC, you do not need any backups, you should 
demote any none working DC's (forcibly if necessary) and create new DC's

You only need a backup if you suffer a catastrophic failure and need to 
rebuild your entire domain. With good backups, you should be able to 
rebuild your domain.

Note that the samba-tool backup tools will not backup any data in shares 
other than the default ones created by a provision or join. You will 
need to back these up separately.

You only really need to backup on one DC, but backing up other DC's for 
redundancy reasons will not hurt.
