In networker Level 1-9 back up files that have changed since the last lower
numbered backup level.
I cannot find that ther is an exclusion for level 9.

Incremental backups files that have chaged since the last backup,
regardless of the level.

So in your case I think you need an incremental for all other days.

I have networker 7.1.

I do weekly level 1 through 8 backups every wednesday and
level 9 backups all other days.

I realize that an incremental backup is everything that has changed
since the last backup regardless of what that backup level is.

As I understand the level 9 backup it's everything that has
changed since the last lower level backup excluding a level 9.
So if I do a level 1 backup on Wednesday and two level 9's in a row on 2 on
Thursday and Friday ,the Friday backup will backup everyyting since the
level 1 on Wednesday is that right?

I'm backing up over 100gigs every day on one of my clients and I
know that there are not 100 gigs of changes being made. I believe this
is due to the fact that I'm using Level 9 backups each day instead of
incrementals. Sound right?

My question is do most people use level 9's or do you use incrementals?

Thanks  much.
