SYNOPSIS
The yum-fs-snapshot package
DESCRIPTION
yum-fs-snapshot(1) is a Yum plugin for taking snapshots of your
filesystems before running a yum transaction. By default it will take
a snapshot of any filesystem that can be snapshotted, which currently
is limited to BTRFS filesystems. However, all filesystems built on LVM
logical volumes may be snapshotted at the block level using LVM
snapshots. LVM snapshot support is provided for the purpose of system
rollback. As such LVM snapshots will only be created if the kernel
supports the "snapshot-merge" DM target.
FILES
yum-fs-snapshot uses a configuration file for its specific actions:
