A level 8 will backup data since the last lower level , but the same
level previously has no effect.

Two level 8's will back up all changes since the last full , or level 7
or below..

To get the effect of an incremental you need to increment the number
each time.

Subject: [Networker] Question on level 8 backup?

I ran a level 8 for a group (several clients), and it backed up a bunch
of data. All the previous backups since the previous full had been
incrementals. Then I ran another level 8 the next day - no other backups
between the two level 8s -and it backs up a bunch of data again. This
seems odd. I thought a level backup will only capture all files that
have changed since the last lower number backup or backup of that same
level.
So, the second level 8 should not have gone back to the previous full
like the first one did. Instead, it should have only grabbed any data
that changed since the previous level 8, right? In essence, it should
behave like an incremental in this *particular* case, correct?

Today I ran an incremental estimate on the group (savegrp -n -l incr
group_name) and it reports a small amount of data, but when I ran a
level 8 estimate it reports a large amount again.

Why would this happen?

We're running 7.2.2 on Solaris 2.9 with two RH Linux snodes, each
running 7.2.2. Clients are running 7.2.2 on Linux also.
