Hello, Thanks for all informations provided.
I just realize that rsnapshot support LVM since 1.3.1 release, as mentionned in the manpage (example with your case): backup lvm://lizzie/root/etc lizzie/ You have to define some variables to take advantages of this feature: linux_lvm_cmd_lvcreate /sbin/lvcreate linux_lvm_cmd_lvremove /sbin/lvremove linux_lvm_cmd_mount /bin/mount linux_lvm_cmd_umount /bin/umount linux_lvm_snapshotsize 256M linux_lvm_snapshotname rsnapshot linux_lvm_vgpath /dev linux_lvm_mountpath /mnt Is this corresponding to your needs ? -- Guillaume Delacour
