mkcp8
Make a nilfs2 checkpoint
Usage
mkcp [options]
[{device | node}]
Overview
mkcp is a utility for making a checkpoint or snapshot for the NILFS2 file system found in device. device may be a block device or a filesystem node (file or directory) on the filesystem. When device is omitted, it tries to find a NILFS2 file system from /proc/mounts.
This command is valid only for mounted NILFS2 file systems, and will fail if the device has no active mounts.
