Creating and mounting a snapshot file system

The first step in backing up a VxFS file system is to create and mount a snapshot file system.

 To create and mount a snapshot of a VxFS file system

mount [-F vxfs] -o snapof=source,[snapsize=size] \
destination snap_mount_point

Example of creating and mounting a snapshot of a VxFS file system

The following example creates a snapshot file system of the file system at /home on /dev/vx/dsk/fsvol/vol1, and mounts it at /snapmount.

 To create and mount a snapshot file system of a file system

# mount -F vxfs -o snapof=/home, \
  snapsize=32768 /dev/vx/dsk/fsvol/vol1 /snapmount

You can now back up the file system.
