Greetings,

I'm running 3.0-current with 2 EIDE hard drives.  Is it possible to take 
a snapshot of the entire first hard drive, compress it into 1 file and 
store it in the 2nd hard drive?  If so, what's the best way to do this?  
I searched the freebsd archives but I could only find info for creating 
tar or dump files to tape.

The reason I'm doing this is, I want to periodically take a snapshot of 
the entire system as a backup and store it on the 2nd drive which is 
currently not being used.  If for some reason I screw up another upgade 
(like I did going from 2.2 -Beta --> 3.0 current) I want to restore the 
primary drive from 2.1.5R CDROM with a minimum installation and then 
take the most recent copy from the 2nd disk and umcompress it on top of 
the minimal install on the 1st drive.  Am I crazy (or stupid) for 
attempting this?

Has anybody done something similar to this?

Here's the output from df -k for this system:

bash$ df -k
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/wd0a       31775    16885    12348    58%    /

/dev/wd0s1e     63567     2478    56004     4%    /var
procfs              4        4        0   100%    /proc
bash$ 

Oh, BTW, this is a 100% Mickey$oft free system!

Thanks in advance for your help.
