Interating through a feature dataset to automate backup

Hi,

I'm trying to automate the backup of a feature dataset in a GDB on a database server to a GDB on a network drive. The locations of the input feature dataset and the output GDB are hard coded for now.

The model goes through the following steps:

1. Creates a feature dataset on the network drive named 'backup_<yyyymmdd>'

2. Iterates through the feature classess, calculates an output name for each and copies the feature class to the network drive.

My problem is that the model works fine when I set the iterator to use line features only, but when I don't specify or select points, the model stops with the following error:

ERROR 000260: Failed to copy Database Connections\AIA-MSDB02@AIA_GIS@giscreator.sde\AIA_GIS.GISCREATOR.Terminals\AIA_GIS.GISCREATOR.DTB_ANNO into X:\Map Requests\2013\Job2378_Automate_Monthly_Backup\GISBackupTest.gdb\backup_20130708\July082013_DTB_ANNO
The table already exists.

The table 'July082013_DTB_ANNO' does not show up in ArcCatalog and even when I delete the feature dataset and start over, I get the same error.

The model consists of two tools, BackupTerminals, which creates the feature dataset and IterateTerminals, which iterates through the feature classes in the source and copies them to the destination under new names:

Can someone perhaps see why the model fails on point type feature classes? Or is the error message a red herring and something else is going on?

Thanks
