Use the following command. It will help you to create Snapshot while the File system is Currently mounted and system runs at run level 3.

#/usr/sbin/fssnap -F ufs -o <options maxsize, minsize of backing store file> bs= <specify backing store file path> <snapshot filename path>

Some notes:

*Backing store should not be in a same file system which is going to be Snapshot.

*It will create /dev/fssnap/0 and /dev/rfssnap/0 which will help you to take back-up of snapshoted FS using ufsdump command.
