Steve

There are no options like in Windows to set archive bit or choose
date/time - I looked for that, could not find it.

 

Although it looks like ctime is used to rely on when nbu treats a full
and an incr

 

So will try that

is doing fulls

        This is not UNIX specific but I would verify the following

         

        1) Full and the INC are in the same policy. INC backups only
check against FULLs if they are in the same policy.

         

        2) Not sure if this applies to UNIX but are you doing backups
based on modified time or Archive bit. I have seen some applications
(virus scanners mostly) that change the modified time of a file when it
scans it.

         

        I cant think of any reason why a STU change would cause this but
a Policy change could.

         

        Hope that helps

        Guys

        Not knowing much about Unix, wonder if you can help

         

        Have a single NBU 4.5 Master backing up a NAS over the Network.

         

        2 weeks ago, they lost their storage unit. This had to be
deleted and re-created using tpautoconf (I think!).

        Got it back, and got the backups working.

         

        However, the Cumulative incrementals are doing FULL backups,
even though FULL backups are completing ok.

         

        Is there anything I can check in Unix to find out why it could
be doing this?

        Any suggestions welcome

        Thanks
