big incremental backup
Sorry I may have said winner to early.
I am not looking at this again.
The full backup I forced worked great. The next one that ran said finished but was almost twice as big.
Then an incremental kicked off over the weekend and was at twice the doubled full backup when I cancelled it. It is like it does not know how to mark files as being backup up or something I am not sure.
So looking into this some more and maybe going to get the customer to just buy some 1.5tb drives and hope that they work.
