some of the archives I wasn't able to clearly answer my question, only
find bits & pieces.
Situation:
I have a web & mail server (production) and a backup machine. The two
machines are near identical as far as hardware & software
installation. I use the backup machine as a mirror of the main. If
for any reason mail functionality dies I can redirect to the mirror,
etc.
My question is can I use rsync to safely mirror the entire drive?
Currently I have just mirrored /var/www/ & /var/mail/. I'm sure there
are other files that may be regularly updates (ie; logs) and I want to
make sure the backup-mirror is completely up to date.
Is it safe to just rsync [remote]:/ [local];/ ? Would the /dev or
other folders cause issues with this? Would it be safer to implement
a more detailed rsync script excluding certain areas?
/proc and /sys need to be excluded.
Cheers -e
