The Amanda backup system is a great resource for backing up your Linux system. One of the things I noticed with the latest version is that the exclusion list has been breaking. For instance, Amanda backups are now backing up the /tmp folder, which causes it complain with the PHP session lock files. All was needed to fix was adding a leading dot in front of each folder.
Here’s is a copy of my working amanda.gtar file:
./tmp
./dev
./sys
./config
./proc
./mnt
./cdrom
./lost+found
./opt
