Some Backup Sets are multiplied

Hello,

I'm just evaluating Backup Exec 2012 for vmWare ESX VMs and file backup. I've installed it on the virtual machine and added RAW disk mapping for Deduplicated disk storage.

Backups run fine, exept sometimes it takes longer time than allowed or storage is out of space.

So I'm looking what exactly is taking so much space. I wonder why on the "Backup Sets" section some objects are listed multiple times with exactly the same properties. On ESX object usually it is "Full" and for file it is "Snapshot" Backup Method. I've included the screenshot in the attachment.

First question: is it normal behaviour of BE 2012?

Second question: is it safe to delete dublicates?

Best regards,

Mantas L.
