After installing 10.8 Tme Machine keeps saying the drive is unavailable when a BU is started. Help
I'm having the same problem with my QNAP TS-112 NAS. It appears that Time Machine is broken in Mountain Lion, at least in relation to non-Apple NAS devices. I don't know if the same problem occurs with a Time Crapsule, since mine died a few weeks ago.

Most NASs that worked on Lion do work with Mountain Lion (as do Time Capsules).
Especially if you upgraded directly from Snow Leopard, it may need an upgrade. Check with the maker.
If that doesn't help, try re-selecting it in TM Preferences.
If still no help, try a "full reset" of TM per #A4 in Time Machine - Troubleshooting.

I solved the problem with my QNAP by first connecting to the network drive and logging in so that it mounted on the desktop, then selected it from Time Machine Preferences. Now it works as before.

With the Seagate BA NAS TM wont work. Same like last year with the update to Lion. Seagate needs 5 months to make an update
I will sell my Seagate NAS and will buy me an synology. They have updated their products. No problems at all and support answers questions. Seagate don´t either.

You won´t get an answer from Seagate. I have asked them 3 weeks before (problem exists since ML DEV Preview). The same problem was last year with Lion. Seagate needed 5 months to bring an update to fix the issue.

Try this and all will work
In Finder choose GO
Choose connect with server
Type the NAS IP f.i. 192.168.0.100
now open time machine preferences
The nas is now showing as a new drive
Choose this drive
Voila everything works fine now
