Hi,

I checked the listing and didn't see any previous posts that specifically addressed this question.

In the savegroup completion notifications, I sometimes see messages regarding a file that changed, shrunk or grew during save. Log files will, of course, do this, and I know I can create a directive to suppress those warnings, but my question is:

1. When does NetWorker report 'shrunk or grew' versus changed?

2. Does it look at the size of the file before backing it up and then check the size again after the file has been backed up to decide if to report 'shrunk' or 'grew'? What will cause 'changed' as opposed to 'shrunk or grew'?

NOTE: We are using NMO with Oracle, but I do not see any of these messages on those notifications. These messages occur on other non-oracle stuff, but not most of the time, just once in a while.

My assumption is that any such files will be captured again on subsequent incrementals, and there's always going to be some files that will change during the backups - that's obvious - but the wording: 'changed' versus 'shrunk or 'grew' confuses me?

Thanks.

George
