Flar image is a good way to recover your system from crashes. In this post we will see how to create a flar image and use it for recovery of the system.
Flar Creation

It is recommended that you create flar image in single user mode. Shutdown server and boot it in single user.

flarcreate -n my_bkp_image1 -c -S -R / -x /flash /flash/recovery_image.flar

Once the flar image is created. Copy it to your repository system. Here we are using NFS.

cp -p /flash/recovery_image.flar /net/FLAR_recovery/recovery_image.flar
