we need to setup a backup system in our office and need advice on how to best approach this.
The servers needing backup are as follows:
1. Email server using ubuntu, postfix, dovecot
I wanted to ensure that in the event of hardware failure such as motherboard or hdd, we can simply buy another machine and keep going. Also, we need to keep the email data and settings such as the user information and setup files.
2. Fax server using ubuntu, hylafax, postfix, dovecot
Same objective as above
3. Instant messaging server using virtual computer, virtualbox, ubuntu, openfire
Same obj as above
4. Windows server
Since (to me anyway) setup is easier, we're not too concerned on the os backup.
We're more interested in the file backup. So this is not exactly a problem for us.
The only important point is that we'd like to backup the windows servers to the same backup server as the abovementioned linux servers.
5. Finally I'd also like to backup syslog and system events to one backup location.
Ideas so far:
Is to provide a backup server and back up to either fixed or removable hdd.
Have looked at (but dont understand much) on rsync, bacula and remastersys.
