What is the purpose of enabling Shadow Copies snapshot twice daily when I cannot restore files from Previous Versions ?

Hi All,

May I know what is the purpose of enabling the Windows Shadow Copies feature in each of the drives when I cannot preform Previous Version easy file restore ?

See below options:
VSS option
Note: the Drives here are all presented from HP EVA 6400 Storage array LUN as NTFS.

An see the below Previous Options that cannot be used at all:
Previous Version
Any thoughts and comment would be greatly appreciated.

Thanks.

The reason I ask is because it cause my Backup Exec 2012 to failed randomly. I've tried to backup the same files using Windows Backup and it is also failed.

You also have to enable system protection on that drive.

where is that option is configured ?
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

In the screenshots provided it shows that shadow copies are disabled for every drive so you won't have any previous versions to recover from at the moment (first window).

It's upto you if you want to use it, personally I have them on as it's easier to recover a file from that then it is from a backup sometimes (especially when the backup tape needed is unavailable at the time).

If you enable it on the drive (just select the drive and click the enable button) and let the shadow copies run you should find previous versions become available.
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
Well I'm not sure why it is on like that.

The drive are LUNs presented from array to hold VM backup files which is quite large 20 - 450 GB files and some files grow up to 2 TB.

So I don't know why this setting was left on by my predecessor in my backup server LUN
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
ok, It seems that it is not required to restore the 3rd party backup files which is quite large (20 - 450 GB files) using the "Previous Versions".

So if I turned off the schedule (remove) and then reboot the server, is that all that I need to do ?

or do I have to cleanup or is there anything that I may need to pay attention to ?
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
My goal is to disable or turn off the Shadow Copies completely here, but somehow I cannot do it from either my user account or DOMAIN\Administrator.

The screenshot below shows the error after I've deleted the two default schedule of VSS and reboot the server
After deleting the default VSS schedule
Upon checking on the Scheduled task, somehow there are some job that is automatically created and logged by NT AUTHORITY\System for each of the drives, see below:
SchedTask
how to remove and stop the VSS snapshot completely ?
My backup software is now failing to backup the files to the tape drive.
Andy MIT Systems ManagerCommented:
Looks like there a configuration issue on the server - from the screenshots provided the shadow copies are turned off and have not created any shadow copies (all drives showing 0 bytes used).

Regarding the tasks - you could try disabling them to see if that helps with the problem. Could be that task scheduler is trying to run the task but shadow volume copies is not correctly configured resulting in problems with it.
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
Yes that's seems to be the case, but how to completely stop it ?

The backup is failing with backup exec and windows backup.
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
the problem still exist, even when the scheduled tasks are all disabled.

Here's the event logged:

May be worth having a look through this forum post https://social.technet.microsoft.com/Forums/en-US/c0e5171d-90ee-40f0-a612-3b46aa716a75/unable-to-schedule-shadow-copies-access-denied 

Looks like permissions can sometimes cause this particular error.
Senior IT System EngineerSenior Systems EngineerAuthor Commented:
Hi Andy,

The article points to this KB article https://support.microsoft.com/en-au/kb/926959 from Microsoft regarding SharePoint.

In my case here I do not have SharePoint in the problem server.
Andy MIT Systems ManagerCommented:
Hi

The sharepoint part is irrelevant - the article is just used to desribe how to assign permissions to administer the scheduled tasks.

You could try deleting the scheduled task, go back into shadow copies and try setting up a new schedule for the appropriate drive to see if the problem still persists (I would test this on one drive first to see if it works).
