My current scenario is that, I am using Ubuntu Linux 14.04.1 Server. Servers Installed Apache Webserver BIND DNS Server Dovecot IMAP/POP3 Server MySQL Database Server Postfix Mail Server PostgreSQL Database Server Procmail Mail Filter ProFTPD Server Read User Mail Samba Windows File Sharing SSH Server Virtualmin Virtual Servers (GPL) Webalizer Logfile Analysis

There are two hard drives attached sda/500Gb & sdb/500Gb

Mostly i use webmin for system configuration.

Please someone tell me how to synchronize full data sda to sdb while running my server. Just like mirror Hard Drive. and Mirror on daily basis. I want to make it like if sda failed then sdb take it's place.

Sorry for my bad English.

Regards.

What you need is RAID.

More: you need RAID-1. There are various types, you can read up on the Internet about how to set up your hard drives in these combinations.

  • "you can read about it on the internet" is not an answer. – psusi Nov 17 '14 at 14:19
  • It looked like he hadn't done the basic research - he didn't even mention RAID anywhere. So I pointed him to the right direction. Agreed, it could have been a comment. – SiddharthaRT Nov 18 '14 at 5:31
  • Also, I believe we dont need user manuals as answers in AskUbuntu. – SiddharthaRT Nov 18 '14 at 5:32
  • @SiddharthaRT thanks man. That is what i really want, a starting point. :) and i am glad that everyone else gave such a positive help. – Aadeel S. Puri Nov 18 '14 at 6:10
