I‘m using dump command to backup file systems to tape and remote server. However, I’m not able to find any option that will allow me to exclude files or directories from backup. How do I force UNIX / Linux / FreeBSD dump command to exclude selected files (such as /var/cache or /usr/basejails) which I don’t want to backup?
My current /usr file system was full, so I ended up adding a new disk to my FreeBSD server. I’ve created a new partition at /dev/ad6s1 (size is 250G). How do I move my /usr file system over to my huge new disk at /dev/ad6s1?
