Fastest way to get an entire FBSD system back online?

[Ed Flecko]

Hi folks,
I confess I'm more familiar with "Windows" and for years I have
"Ghosted" PCs as a very fast way to get an entire PC back online in
the event of a drive failure. I can easily get a PC back online within
the hour using "ghost" (or some drive imaging software).

Is there something similar in the FBSD arena?...some form of "backing
up" a server so that if a drive fails, upon replacement of the
drive(s), the OS can be very quickly recovered from a backup (of some
sort), or from an image, etc.?

What options are available??? Suggestions???

Thank you,
Ed
