Backing up LVs

[Gabriel M Dragffy]

Hi, until recently I've always used the old style of paritioning, using
primary and extended partitions. This was great for backing up data and
partitioning, I could do everything I wanted with a partition using
Gparted and back up my home or root partition using acronis true image.

I've now switched to LV and all my old knowledge has been obsoleted. Now
a program like gparted just reads my vg as one huge partition and the
same is true for TrueImage. I want to make a backup of my root partition
(some 4gb) and not all 54gb of the vg. What methods are available to me?

PS. My old method was to create an image file using trueimage on an
external usb hard drive, and this has always been excellent. Is there
something similar I might be able to do now that I using LVs?
