Re: SnapCreator is not deleting snapshots

I have the exact same issue in Snapcreator 4.1.2 GA release.

Snapshots are created correctly, also a snapcreator Backuplist works perfectly:

C:\Program Files\NetApp\Snap_Creator_Framework\scServer4.1.2>snapcreator --server opsmgr01 --port 8888 --profile Application_servers --config fileserver01_snapdrive_hourly_XDP --action backupList --policy hourly --debug --verbose

This is the relevant snapshot part in my config file:

In my debug log I see the following when running the Backup with policy hourly:

########## Running Snapshot copy Delete on Primary ##########
[2016-07-19 13:17:16,845] INFO: Application not defined. Skipping cleanup task

So nothing gets deleted and my backup start failing as soon as 255 snapshots have been reached on the volume.

PS: I also tried setting NTAP_SNAPSHOT_RETENTIONS=HOURLY:12 to NTAP_SNAPSHOT_RETENTIONS=hourly:12 without result.

Any idea ?
