Backup Exec 2012 - Backup to Disk Performance
i have an issue with BackupExec 2012.
I uninstalled BE2010 und installed BE2012 last Week on a Server. (HP DL380G7, 4GB RAM, 1GB/s). My customer reported me a bad Performance for disk backup over LAN. He also reports, a backup to disk with the prevous BE2010 Installation was much faster. Unfortunatelly he can't tell me, what "much" faster means. Old Backup HTML Reports are not available.
So i tried to analyse the Problem and copied per UNC Share 4 files à 1,5GB from a remote Server over LAN to my Backup Exec Server on Drive D:\ (where only my Backup to Disk Folder exists). I have got a throughput of 5.800MB/min. In my opinion a really good Gigabit Speed.
After that i created a Backup Job in Backup Exec 2012 on Disk. Same Files. Same Remote Server. Same Target (D:\).
Here i have got a throughput of 2100MB/min in the Job Summary.
My Customer asked me why and right now i don't have a good answer.
What happend here? Why is there so a big difference?
Maybe someone has a Solution, Idea or Explanation for that.
