Hi *,

We have been running TSM backups for a while now in a Windows clustered 
environment. We are running into a problem and it appears a whole volume has 
what seems like a full incremental backup being taken when it shouldbe an 
incremental. IBM has confirmed that if you enale Microsoft security on a volume 
that TSM will see that whole volume as new and a full incremental will occur ( 
this happened to us over the weekend on two volumes ). However, another 
unrelated volume had a full incremental backup last night even though we did a 
first full incremenatal a month ago and TSM has been doing incremental backups 
ever since. The Microsoft  security was NOT enabled on this volume. Does anyone 
know what can cause this behaviour ?

TSM 5.3.3.0 on AIX 5.2 ML9
