NtfsDisableLastAccessUpdate
All, TSM 7.1.1 environment. My Windows fileserver colleague is asking me about any potential backup ramifications from disabling the LastAccessUpdate on our new Windows 2012R2 fileservers. I didn't find any definitive answers via Mr. Google so I thought I'd reach out and see if anyone in the group had some knowledge. My offhand thought is that since we don't do any HSM, we don't really use this particular bit, but... Here is what he asked: By default Windows Server 2012 R2 disabled Last Access Update on files and folders. This is the registry location where this is stored: HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisableLastAccessUpdate This KB articles discusses this and it says this: https://technet.microsoft.com/en-us/library/cc785435.aspx The disablelastaccess parameter can affect programs such as Backup and Remote Storage that rely on this feature. Does the TSM Baclient rely on this value? With it disabled do we lose anything with TSM?

Re: NtfsDisableLastAccessUpdate
Your offhand thought is correct. NtfsDisableLastAccessUpdate goes all the way back to Windows 2000 where the time stamp of a directory would change if you did something with the files in it. I find it hard to imagine that anyone backs up based on the last-access time stamp and not the last-written time stamp? - Bent -Original Message- All, TSM 7.1.1 environment.
