I searched for a while on this, but I have not found an answer that worked.
1. I have Server 2012 Essentials. I have others running w/o any issues and I did not configure this one any different.
2. I have about 380GB of Data files that need twice a day backups. Not on OS drive, I would like backups of both. I am not running any server application besides AV monitoring.
3. I am using a 2TB WD Ext-HD - so plenty of room.
4. I have it backing up twice a day noon and 11PM
5. It is only keeping the backups for about a day. Once the backup runs again it disappears.
I have tried changing it to incremental and starting the wizard over again w/o any different results.
