The combination of LVM with a journalled filesystem under Linux is similar 
to AdvFS under Tru64.  One difference is that with Linux LVM you have to 
unmount a partition to resize it.  Another is that AdvFS allows you to 
defragment a live filesystem.

The disadvantage of this is that your backups aren't portable to another OS.

There are no special backup tools for LVM partitions under Linux.  Just use 
pax,
tar, cpio, afio or whatever you normally use (but not dump)!
