[NBLUG/talk] Duplicating a server

[Todd Cary]

Sameer -

Yes!  It worked very nicely; at least as far as I can tell.  If I have 
time today, I'll switch my router over to the 'standby server" and make 
sure that it works.  What I found interesting is that the 
owner/group/permissions seem intact.  Of course, I had manually 
recreated the users on the "standby server".

Now some frosting on the cake would be a way to synchronize the 
Users/Groups!  Can this be done?

Also, I am asked for a password for the destination which would be a 
problem for a crontab.  This was true with

  rsync  -a -e ssh /home/ 192.168.0.22:/home/

and

  rsync  -a  /home/ 192.168.0.22:/home/

Is there a way to eliminate the password?  Maybe I missed it in the Man 
pages.

P.S. Probably I am going to have to break out my old Perl book and write 
some scripts to backup my Interbaase and MySQL databases...been a long time.
