We use custom attributes on VMs to add more information about them.
Someone has accidently deleted one of the global attributes and all of the information the attribute contained about every VM.
I have VC database backup, but how can I restore only the attributes and not the entire database?
You could try a tool that will scan the DB transacion and allow you to choose which statements to build a restore script from (DROP DELETE). A few years ago I had to restore the contact details from a helpdesk system that someone didn't delete honest.. The tools I used was from ApexSQL
