Backup Restoration Data Staging
Hello,
I am currently working to restore a small directory. During the restore process the job has failed due to insufficient space to stage. I was able to get the job to complete. But, I had to build a 1TB drive on my SAN and attach it to my Backup Exec Media server via iSCSI. During the restore job the SAN became completely bogged down and would not allow users to log into their virtual environments. The restore is going from TAPE to a Redirected File location on the Media Server. Backed up Drive Size where the Directory resides is 1.4TB. During the restore there were no other jobs running on the Backup Exec Media Server.
Question 1: How much data needs to be staged?
Question 2: Do I need to stage Data? (Is there a way to set up my restorations to be direct?)
Question 3: Is it normal for a restoration using my configuration to bog down the entire SAN?

Hi
Question 1: How much data needs to be staged?
While doing GRT restore from vmdk it will stage the entire VMDK first to staging location and then perform the restore ,once the restore is done it will delete this from the staging location
Question 2: Do I need to stage Data? (Is there a way to set up my restorations to be direct?)
Yes you have to stage data when doing GRT restore from tape ,alternative would be to do duplicate job from tape to disk and then perform restore from disk which will not require Amy staging ,but then to duplicate it will require the same amount of space as staging only advantage is that if restore fails staging has to be done again and it is time consuming when you are staging this big amount of data so it is good to duplicate and then do restore
To create duplicate job check link below

Question 3: Is it normal for a restoration using my configuration to bog down the entire SAN?
It should not actually but then it would be to do something with the configuration check the Antivirus setting and also you can isolate this by connecting the USB drive locally to media server which is is from than 2 TB and free.
