We did the same about 5 years ago. Originally started using the DLM and Data Domain just for the mainframe data. We also replicate to our cold site with a matching pair. We started adding more Windows related data using SQL DD Boost and server Veeam backups to it.
We absolutely zero performance issues on backups. We do see performance issues on Windows restores when it needs to reconstitute all the dedupped/compressed data such that it has me looking at alternatives. We do not see this issue on the mainframe data, just Windows.

I am trying to understand about backup cycles using EMC DLM when we use single backup solution and single virtual tape library to backup both mainframe and open systems. Is there a possibility for contention ? Will there be a impact to mainframe backup when there is a high backup volume for open system ? These performance do effect the open system as well ? Trying to understand these from the DLM users ? Any feedback would be appreciated Jake. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
