Differential incremental running as full backup

You need to let Netbackup do its work. If it think it need a new full backup, don't cancel it because it will try a full backup again.

With the new schedules the diff schedule may think it is missing a reference to a full, and therefor be backing up everything. So did you change the schedules between the full and diff schedule. The details of the activity monitor will mention if it's missing a reference to a full.

Please check policy configuration - schedule in the screen dump should say "DIFFERENTIAL" insted it say "MONDAY" - the name of the old schedule setup

Does having the master server at a lower level thna the client perhaps cause this?

Can you give us the job status of when each schedules run , including the last full schedule?

Were they all ending in status 0 , or some has status 1?

In host properties of lasfs01.corp,  is it set to use archive bit or timestamp?

Also just saw your backup selection is a DFSR , how big is that folder? According to admin guide, there is certain recommendation for policy setup - please check it out , look for "About Microsoft DSFR backups"

You got 4 Differential Incremental Backup schedules, you should have one.

A diff incremental will automatick kick off when frequency is set to 1 days and no schedules with higer retention are about to run 

@watsons - all finished with status 0. It is set to archive bit.

This folder is about 4 TB.

@nicolai - if I have a full weekly that has a 2 week retention, and a differential policy with 2 week retention, will this be an issue? Does the retention have to be greater?

Always ensure the full backup is retained 1- 2 weeks longer than the incremental.

Incremental backup is tied up to the full backup, if you have no full backup as a reference you may not be able to restore data until the next full

Picture this:

F = Full 

i = Incremental

What you should have :  F i i i i i i F i i i i i i 

Now if the full is expired before incremental :  i i i i i i  F i i i i i i

Basically there is only ONE full backup to perform a entire system restore. if that backup is damaged, data loss will occur.

Hope i managed to picture the problem :-)

As said those schedules are way too complicated .. and don't actually what they / you suggest.

The BIWeekly only actually runs once a month with the monthly running the other time to give the effect of a full backup every 2 weeks.

The timing is pretty close too - so i would make the biweekly one have a retention of 4 weeks to be fully sure and then just one one differential incremental backup schedule with a window of 2200 to 0400 for each of Monday, Tuesday, Wednesday and Thursday and a frequency of 7 hours to make sure it is always ready to run.

It appears the full ran on Tuesday, and Monday based on the amount of data of backed up. (Monday and Tuesday are suppose to be incremental).

The last scheduled full backup happened 2 weekends ago

Then differential incremental backups monday-thursday.
