Problem
The backup size for a DLE is the same regardless of the backup level.
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.
