DNS and DHCP backup

We have a windows2008 server which host AD integrated DHCP and DNS. We do regular file and folder backup os so drive.
Is this backup enough to recover the dhcp and dans in case there is an issue with current server?

i have seen several postings which talk about netsh and DHCP backup and restore.
What is the difference between nets and DHCP backup ?

There is no such thing as "AD integrated" DHCP. You can authorize DHCP in AD, but that is *very* different. Yes, you can recover DHCP with a file level backup in a worst case scenario.

For DNS, if you are AD integrated (which *is* a thing in AD) then DNS zone itself is stored in the AD database and must be restored as part of an AD restore. Which, like the rest of AD, is *not* file based. AD backups are a part of system state, and restores must be planned and understood carefully as authoritative or non-authoritative on an object basis.

For most small deployments (where you'd only have one DC), I wouldn't bother backing up DHCP.  Odds are you could simply recreate your scope faster than restoring the database.
