Almost. Since xfsdump uses mountpoints, you'll need to dump /tmp (no
trailing slash) instead of /tmp/llama/. That's provided /tmp is a
mountpoint. When using xfsrestore, you can put it anywhere, only xfsdump
is mountpoint dependent. Or you can use the -s flag to specify only
/tmp/llama. The syntax would be such as:
ssh hostname xfsdump - /tmp -s llama | xfsrestore - /
Otherwise it should be fine.
