I currently have 2 volume's:
[root@compute4 /]# lvscan ACTIVE '/dev/vps/vm108_img' [30.00 GB] inherit ACTIVE '/dev/vps/vm109_img' [90.00 GB] inherit
Now, I use the LVM snapshot function to create backups. My quesion is, what size does the snapshot needs to be? Atleast the same as the volume in question or can it be a lot smaller and will only the changes be saved into it?
