mkcp — make a NILFS2 checkpoint


mkcp [options] [device]


mkcp is a utility for making a checkpoint or snapshot for the NILFS2 file system found in device.  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.
