thx very much for quick answer. My knowledge on Veeam ONE is rather limited as during my testing I have found it a bit confusing...
I checked the links, and there are lots of report, only these are on hig level and on logging of the tape procedures and stuff- I'm not able to find anything on the mediset content
To clarify - the 'content' here is a complete list of included Veeam backup FILES and specifying the (virtual) servers stored in each file - and - information on backup date, status, expiry and so on.
Key point is during a disaster recovery to be able to pinpoint the exact tape(s) to restore a specific server - in accordance with our prioritised recovery list... AND based on the asumption that Veeam itself was clean installed on new servers.
