Backup Exec 15 locate level 0 dumps for incremental backups

Hello everyone I'm Kerim,

We have an issue with incremental backups. "Date of last level 0 dump: Tue Aug  8 16:32:08 2017"

Last level 0 dump is created with a full backup on 20.07.2020, logs can be seen below. Somehow incremental backups can't locate or read our level 0 dump files and takes full backup instead. 

Our tapes are almost doubled their numbers and it's growing further because of this issue.

Is there any possible solution without deleting and creating any jobs ?

Full backup logs and incremental backup logs are below.

Re: Backup Exec 15 locate level 0 dumps for incremental backups

For your incremental backups, did you select the different NDMP levels in your job definition. e..g.

incr. 1 - level 1

incr 2 - level 2

...

incr 9 - level 9

See the article below on how you should configure your NDMP backups.

Re: Backup Exec 15 locate level 0 dumps for incremental backups

@kerimtav 

Please also ask the filer admin to double-check /etc/dumpdates on the filer. 
What is the modification date on the file? 
And contents of the file - what is last entry? 

Is the filer date/time correct?
