enabling of back up server

[erastus@connect]

Hi Guys,

My main server failed. Now trying to activate the backup server. It was supposed to be a hot backup. ( Yuuup) I paid to get it done but it is not done.

Please have a look the data is configured as no local mail and no local data.

How can I change this server so that I can use it while fixing the main server?

Seems like you only have a backup-dns server, that's something completely different then a backup server. If you paid for a complete backup server, I would suggest you first contact the company you payed for it.

You can't use this server, if you don't also have the useraccounts on there with their public_html etc.

Or do you have those on your backup server and is only the dns data non-local?

Thanks Richard,

Juup learned the hard way. Get burned but now I am deleting each domain and recreating it from back up files.
It is nice that I coppied the back iup files accross via scp so I am +/- 36 - 48 hours out of synch with Sunday being 24 hours of the 48

You're welcome.
Glad to hear you were able to copye the backup files via scp. Indeed you lose a lot of hours, but better that then loosing everything.
This is exactly the reason that we run raid 1 on every server nowadays.

Good luck!

Richard,

I have 5 drives what controller are you using?
I need to redo and set up raid 1

With 5 drives i would highly suggest a RAID5 or RAID6

Regards

As I've always said, and I'll say it now, my choice is 2 x RAID1, + 1 SPARE disk.

Using 5 disk in a LVM is very dangerous and insecure, as in case if any disk fails, there might be no chance to recover data.

Hi Andrea,

Busy converting my systems to raid 5 minimum

ALex,

We paid an installation to do it with raid.
The problem was they did a raid 0 not a raid 5.
The idea was to have at least 3 working drives with each having Centos etc and then 1 or 2 spare drives.
But it was not done
This time it will be done correctly
