Symantec Backup Exec Fun

Nathan Simon Nathan Simon Profile: Nathan Simon

Backup Exec is a great application, my personal favorite. Recently I had issues with a backup, as you can see in one of my previous posts… the backup works fine, although compression will not turn on. It is known by most Backup Exec experts that Symantec Backup Exec enables compression when the job starts(if compression is configurable), but how do YOU know if Backup Exec is doing its job and possible the drive is to blame?

Well here is the answer, its called SGMON, its a debug tool that is used to view debugging information for Backup Exec components and services. SGMON is in “C:\Program Files\Symantec\Backup Exec\SGMON.exe for Backup Exec 12.5d installations. Earlier revisions its buried in the Symantec Backup Exec folder, best bet is to just search for sgmon.exe and you’ll find it easy enough. 

Run SGMON, check off Job Engine; as below…

Click “Capture to File also. Leave SGMON running while you start a job, wait for the job to finish, next thing you need to do is locate the file. For Backup Exec 12d its located here; “C:\Program Files\Symantec\Backup Exec\Logs\servername-SGMON.log”

Do a search in the log file for compression, as below…

Once you are sure that Backup Exec is doing what it is supposed to do, and compression isn’t working as you can tell under the media tab. and the appropriate Media Set as shown below… MIND You when compression just isnt working you will see 1:1 instead of 2.3:1.

SGMON can be used for many things, you can find the official documentation here

Anyways, I’m off for now.

Any Questions you know what to do!

    Have you tried to download lastest driver update from Symantec? Another way is to remove all drivers from the system using Symantec's application called tapeinst.exe and then download the proper drivers from HP.com for your tape drive. Then restart either the server or all the Backup Exec Services. Try SGMON again, it seems to me that the drivers are not reporting to backup exec that they have the capability to compress the data. Make sure Jobengine is checked off. Let me know.
