How to configure for consistant backups

Hello Guys,

   So far I am loving this app, However I noticed that in this tutorial/HowTo ->  http://www.urbackup.org/client_debian_ubuntu_install.html, number 7 shows how to have a script to help with consistent backups using snapshots. But he put in there BTRFS and I use LVM so I was wondering if anyone had some insight on the commands to run that would work for LVM. 

ex: btrfs subvolume delete /mnt/snap_root

Do I just use normal file commands to deal with this or do I use LVM commands and do you have an example?

Thank you very much.

Here are my two files for LVM2,  I am no expert but this is doing the trick for me.  You need to change sizes of LVM2 snapshots if your originals are smaller than the size I am specifying for snapshots.  Files need to be executable 



/etc/urbackup/prefilebackup
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#!/bin/bash

if [ $(mount | grep -c /mnt/snaps/home) == 1 ]
then
        /bin/umount /mnt/snaps/home
fi

if [ $(mount | grep -c /mnt/snaps/opt) == 1 ]
then
        /bin/umount /mnt/snaps/opt
fi

if test -b /dev/rabbit/opt-snap
then
        /sbin/lvremove /dev/rabbit/opt-snap -f
fi
    
if test -b /dev/VolGroup/home-snap
then
        /sbin/lvremove /dev/VolGroup/home-snap -f
fi


lvcreate -s /dev/VolGroup/home  -L10G -n home-snap
lvcreate -s /dev/VolGroup/opt  -L5G -n opt-snap
mount /dev/VolGroup/home-snap /mnt/snaps/home -o ro
mount /dev/VolGroup/opt-snap /mnt/snaps/opt -o ro

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/etc/urbackup/postfilebackup
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#!/bin/bash
/bin/umount /mnt/snaps/home
/bin/umount /mnt/snaps/opt
/sbin/lvremove /dev/VolGroup/home-snap -f
/sbin/lvremove /dev/VolGroup/opt-snap -f
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You will then use the directories in /mn/snaps for your backup directories. You need to have /mnt/snaps/folders already existing for the mount points.
