restoring backup messes up the dns of domain aliasses

[ednique]

First of all it's terrible that there's no dns template functionality for domain aliasses...
I have 38 aliasses and need to change the default dns settings when they are created...
It would be marvelous if someone can tell me where these defaults are hidden, so that I can change them to my likings...


Now the real problem:
I backup my domain with the 38 aliasses...
Then I restore the backup...
All of the sudden all dns settings of the aliasses are messed up...

The changes I do compared to the default; before the backup:
* delete the A record ns.domain.tld
* change the current NS record to another nameserver
* add 2 more NS records
* add a TXT record for the domain

After the restore:
* the A record ns.domain.tld is back
* the NS record is like before
* the added NS records are gone
* but the TXT record is still there

I've checked the main domain that contains these aliasses and his dns settings are correct as I have entered them...

Now I have to change all aliasses again...
