On Tru64 with advfs file system you can have partition and inside

system.
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.
I know, i'm using both.
The point was, multiple file system which share the same physical space.
Backups can be done with the vdump and vrestore.
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)!
I'm using pax for portability.
