Problem
The backup size for a DLE is the same regardless of the backup level.
[edit]
Solution
Set the record value to the yes in the dumptype definition in amanda.conf(5). This will cause the backup program to record the information in /etc/dumpdates or /etc/amandates files on the client, allowing incremental backups to be made.
