Subject About nbackup and incremental

Operating system: Linux CentOS 5.7
NBackup: Physical Backup Manager version LI-V2.5.2.26540 Firebird 2.5

Scenario: I'm using nbackup and my plan is to run a full backup (-B 0) every month and a daily backup with -B 1, replacing the previous 1-level backup everyday. My customer don't generate to much data to have multiples 2-level backup so that I want to avoid many incremental files.

Question: with one 0-level and one 1-level (everyday), is it enough to restore the database? I read that 1-level accumulates the difference since last 0-level backup, is that correct?
