NetBackup and Archive bit

Hello,

 

I am sure this has been asked many times, but I am confused over when the Archive bit gets cleared on a Windows client.

 

I have set up a test folder c:\test that contains 2 files test1.txt and test2.txt.  I did a Full backup.  Both files were backed up and the Archive bit cleared (confirmed by doing a dir /a:a).  I then performed a Cumulative Incremental backup - both files were backed up again.  I then performed a Differential Incremental backup, again, both files were backed up, so I had 3 copies of the files in backup.

 

Now I thought that on a Full backup, the Archive bit gets cleared, so when the Cumulative and Differential were done, they should not have backed up anything at all, so I am confused as to why these 2 files got backed up again with the Cumulative and then again with the Differential.

 

I have a very faint memory of there being a technote that described this, that this only worked when there were a minimum number of files in the folder?

 

Many thanks,

 

Richard.
