This article is a part of the Troubleshooting collection.
Problem
Amanda fails to create level 0 dump but creates incrementals.
Solution
Look at the amdump logs at /etc/amanda/<configuration>/amdump.1 log for errors
One of the possible reasons can be spotted as, from amdump logs
DELAYING DUMPS IF NEEDED, total_size 17273355, tape length 16974848 mark 15 delay: machine.company.com / 20051017 0 [dump larger than tape, 17273214 KB, full dump delayed] now at level 3 delay: Total size now 6615786.
Level 0 dump size estimate is 17273355, which exceeds the tape size. So Amanda creates incrementals.
