I would like to create an exact copy of my live drive on a daily basis via cron. Is there a good mechanism for doing this *without* taking the main drive offline? It seems like the two common backup solutions: dd and rsync both have issues in this area. I don’t think Rsync can create an exact mirror (including partitions) and dd looks like you need to unmount the drive(s) first.
Both drives are of identical size and installed via the ide controller.
I'm a web designer - not an IT guy, as such I'm not 100% on setting up servers/dev environments etc...
I'm freelance and currently working in-house for a client that has set up a dev server that supposedly mirrors their live site - its a catalogue site with loads of dynamic elements.
The dev site they've set up displays only the html, no images or stylesheets link up when i preview them in dreamweaver as they don't logically link to the page as the pages are templates drawn from various folders.
What I want to know is is it possible to mirror a dev server exactly like the live website so the scripts etc all work as they do on the live site. I'm pretty sure it is as I've worked on dev servers before but not one like this bloody mess. The IT bods here seem to think the dev server is the best that is achievable - are they right? am I missing something???
I can't really answer any technical questions apart from i think the dev server is an apache server - what do i need to explain to the IT bods to get my point across?
I currently have a dedicated server with a single hard drive in it with about 800 cPanel accounts. I am purchasing a new server with identical specs but will have 2 hard drives in RAID1 from the same data center.
Is it possible to make an exact image of the first server to avoid any configuration loss on the new server? I have already spoke to the data center about moving the current IPs to the new server and I know moving the cPanel accounts can be done in WHM but I would like to preserve all of the server settings, configurations, and background scripts that I have running.
I need to host livezilla (live chat software) . It needs php and mysql. Which host provider would you recommend? Its not running from my own server. I don't know why, but giving so many errors! I have seen people are using it ..
so, where do i host livezilla?
1- i did Os Reload with new Hard drive for "home"
2- data "backups" drive lost
3- replaced the old home drive as "/old drive"
4- " /old drive " is now the secondry drive in my server and it has the all sites usres and evry thing
5- what i need , to trasfer, copy this sites from " /old drive " to "home"
but data center said
The /olddrive/home directory contains the contents that were previously in the /home directory. You can copy files from this directory to any other directory on your server.
The command to copy files in the UNIX environment is the "cp" command.
The user directories in /olddrive/home directory contain the web page files for the users. However, simply copying the contents over will not recreate the users or domain entries in DNS/httpd. If you wish these back you will need to recreate them manually or restore them from backups.
Primary drive (centos/cpanel) is corrupt
The server is displaying these errors when I tried to do an FSCK:
Bad inode IO
ext3-fs error (device(8,3)) IO Failure
I am having a new primary installed and old primary set as 2nd drive. I need to recover the cpanel domain accounts from this 2nd drive after I mount it with the method below:
mkdir /backup
mount /dev/sdb1 /backup
However, how do I actually recover these accounts in an automated process via whm? I've done this before with the same matter (corrupt primary drive, mount as 2nd, etc) but cannot exactly remember the proper steps.
I just purchased a brand new 10K 150GB drive. How can I take an exact copy of my current drive and transfer everything over to the new drive? I think I need to create a snapshop, or mirror it somehow.
What software will do this? I was told trueimage, but its very pricy, is there anything else?
I have a dedicated box and I started getting Input/output errors today.
I tried:
# fsck
fsck 1.40-WIP (14-Nov-2006)
e2fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried:
# fsck -a -t ext3 /dev/hda2
fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?
I have a Win2K3 server which has 2 hard drives. I was considering backup options and I thought that I might try mirroring Drive A ==> Drive B. I would think that, then, if Drive A has a hardware failure, I could simply switch Drive B into the Primary slot (A) and the server would continue to hum along as nothing has happened. This would reduce the downtime, hopefully.
I have 3 questions.
1. Is this idea practical (will it work)?
2. What is a good software program to use fto handle the mirroring?
3. Any considerations, warnings, technical advice in regard to this method?
I have a VPS-A with company A, within, I have 30 accounts.
Now, I wish to split them with min-impact, ie VPS-A with company A and VPS-B with company B (looking for 1 if you can suggest 1 good VPS company) where VPS-B will host also all the accounts in VPS-A.
Then, I wish to be able to have VPS- B mirror to VPS-A and so, if VPS-A is down, my 100 clients in VPS-A will not be affected and automatically swing to VPS-B.
What is my investment and what should I do to acheive that?
Alternatively, I hope, dreamfully, that VPS-A and VPS-B will be both active and VPS-A are VPS-B mirror and vice-versa.
In VPS-A, I have client 1 - 50 active and client 51- 100 mirror from VPS-B and in VPS-B, I have client 51 - 100 active and client 1 - 50 mirror from VPS-A.
In anything, I can balance the load from both VPSs and if one of the VPS is down, I can swing to the other and still with min-impact.
Then, when my faulty VPS is up, how can I swing back the 50 client to the original VPS?
I hope that my client do not need to change their dns if there is a downtime and also, auto update both VPS if there is an content or email uipdate from my client.
In Short,
1. I'm looking for another good VPS
2. How do I achieve mirroring with auto update to 2nd VPS without having my client changing their DNS when my VPS is down.
3. How do I achieve mirroring and load-balancing between 2 VPS without having my ciient changing their DNS when one of it is down and how to restore back when VPS is up again.
I run a small company and we have a web based application accessed by our customers, this application lets our customers run their business, tracking working, producing parts orders, job cards, invoicing etc.
The database we use is SQL 2005, what we are trying to achieve is have another server, either alongside the existing one, or if it would work at another location where the data from one server is written to the other server, so in the event one server went down we could quickly switch to the second server, my questions -
1, Is this possible?
2, If it is what impact does it have on the performance of server one?
3, Do both servers have to be in the same location?
4, How easy is it to configure assuming its possible.
5, Is there anything else I should be aware of?
my setup to start:
I've got two servers is two different locations.
one of them, the master server ( we'll call server A ), runs a large web site with a lot of content and a mysql server.
I've setup another server ( we'll call server B ), that is completely in sync with server A, both mysql and all data using mysql replication and rsync for data.
also I've setup round robin dns, which is also working correctly.
Now, my question is:
if server A goes down, and server B picks up after it.
how can i get those changes that were made on server B back in sync with server A when it comes back up. example, a use uploads files, or posts/edits/deletes data from mysql.
how should i handle this?
any ideas would be great, I'm sort on stuck on this one for the moment.
We are considering buying rackspace at a datacenter, and setting up two servers. The first would be the primary, lets call it Stewie. The second is called Peter.
Is it possible to setup some sort of either software or hardware solution that automatically mirrors all data from Stewie to Peter automatically?
Basically we want a redundant setup, where if either one of the server fails, the other can take over without any interruption and loss of data.
I was wondering how I can mirror another server, I have a client website and they want redundant DNS so if one of their servers goes offline, the other will keep it up. Any ideas how I can set this up? Is it difficult to do?
View 7 Replies View RelatedWe have a webportal that has a lot of data... and we have different versions of this portal in different languages (russian, italian, chinese).
Now for better performance in china we took a web hosting there and made a copy of the portal there...
It is working as expected but it is really hard to mantain different versions of portals on different servers with separated databases and all other important scripts...
Now we are making a rewrite of our system and this rewrite will use a central database and unified data (so a user of the local (eg chinese) portal will be a user of the global portal too!
Now the portal is based on cakePHP and mySQL... so the business logic scripts and the database are only one for all the portal versions. The only thing that changes for each portal are the config files (one per portal).
Now, making it work on one server is easy but we would like to make mirror servers in russia, china and italy. Lets call them B, C and D and the main server: A.
Obviously all the servers should be in synchronisation between themselves. I've read mySQL has a replication function that would deal with the DB synch. What about other files? The portal allows users to upload their photos, avatars, attach documents and video content. We would like this files to be synchronised too...
B<=>A
C<=>A
D<=>A
and not B<=>C
or B<=>D
How do we achive this?
I am looking for Backup Utility . Came across this two terms
Are RAID 1 & HDD mirroring synonyms?
Which is better RAID 1 & HDD mirroring?
First of all appologies if this is posted in the wrong forum, was unsure of where to ask the following questions.
We have a web server running a web application accessed by a large number of users during a working day. On an evening the web server is set to back up the database to another web server at a different location.
The server is running SQL 2000 ( although we are just upgrading to SQL 2005)
My question is how easy would it be to setup our server so it "mirrors" to our back up server. What I mean by this is that at periods during a working day the database is transfered to our back up server at periodic intervals, say every 15 mins, so that in event we suffer a problem with our main server could re direct our users to our back up server, with little or no data loss?
If this is possible does it also put extra strain on our server that is being accessed, i.e. would users notice a slow down of server as data is moved about?
If all the above is possible, is there any easy way of pointing our domain name at the back up server within say 15mins or so of main server failure? if our main server went down we could not redirect users form main server to back up, so is there any method of making this happen in event of failure of main server?
Does anybody know how I can mirror a websute using PHP?
I have 2 dif domains on different servers different OS, and I need PHP to collect the page from the other server from another domain.
If i want to have a video streaming whats the best way?
I mean im filming something at a studio and want this to be live broadcast to the internet through a server, how can this be done?
i have a server running RH 7.3 Plesk 8.1 and want to upgrade to new version, probably centos, are there any issues i should know about in regards to Plesk?

Even better can any one recommend someone to perform this for me?
have only done static html sites in the past, but am ready to branch out and learn php and mysql. I have watched numerous video tutorials on php,mysql, dreamweaver cs3, and how they all work together.
I have followed all the steps on the tutorials and the website works great on my local testing server, but how in the world do I get it to work live on the internet! This is probably a very stupid question but I am at the point of not caring about looking stupid. I just want to know what Im missing/ doing wrong. The website is hosted with GoDaddy, (and the domain is registered with them as well).Am I supposed to have something set up there or a different server? I have tried using ftp to transfer all files over to the domain but when I visit the domain, the php pages do not work.
What do you all think of 'Live Support'?
Personally, I use it. I like the friendly touch of talking to someone whom responds to my questions directly.
Do you think Live Support is good for;
1. Nothing
2. Sales
3. Tech Support
4. Emergency, etc.
In my experience, Live Support has often been used for technical assistance, and while this is great if you are a one man shop, it doesnt work very well with shift tech support.
Sales is a bit more direct, but - I would personally still prefer a 'record' of the conversation that the client could point to.
Live support may have a valid use during emergency situations, however I am doubting that the personalities that actually answer these live chats can provide any authoritative answers other than 'It'll be ok'.
So, does live chat have a future in Web Hosting, in your opinion?
I have 250-500 dollar budget to beging hosting a social network website with live broadcasting and video streaming capabilities-let's say that it will be something similar to www.livevideo.com. I need a hosting company in USA--Texas is a good place. Let's say that the first month is going to have 200 users a day, and videos are going to be high resolution.

View 4 Replies View RelatedI'm building the infrastructure for a live event site.
I have specced 8 app servers but I'm still unsure with regards to MSSQL.
The site functionality makes a single write to the DB with no reads. A simple option would be to have a MSSQL DB instance on each of the APP servers and simply collate the information after the event.
I've also been looking at the mirroring function of 2005 as it would mean we could get away with two MSSQL servers instead of 8.
Has anyone used MSSQL 2005 Mirroring? Is it easy to setup and maintain? Any caveats?
I have two partitions on my server (C and D), looking to mirror both onto my second IDE drive for some fault tolerance.
Just wanted to know whether there are any real benefits in this.
Secondly, is it worth doing both the primary (c) and the data (d) partitions or having just the data partition and using the free space on the second drive for a backup solution (which would later send data to an off-site backup)?
I want to prepare myself for getting dugg and whatnot, so I want to mirror my site ahead of tiem. The problem is that it's very db-intensive so there's a db that all mirrors would have to query. What's the best way to deal with multiple dedicated servers in order to spread traffic load and not crash my site?
View 3 Replies View RelatedWe’ve been asked to offer a technical proposal for a new established TV station, and the IT manager of the station has a long list of requirements, we covered it all, only one issues lift as we never done it before:
They want about 20-100 GB server for hosting and they want to have a mirror server, incase the 1st server was down, so it would redirect the visitors to the mirror server, I'm thinking of getting them a dedicated or semi-dedicated server, but how do you do the mirror issue.
Some one said to get two dedicated servers, but::
1. How we make it that when one is down, it automatically directed to the other, I believe there is software’s for that, so were do we install this software: the original server or the mirror server.
2. Should they be from two different companies and to different countries?
3. The web site will be with CMS and DB, how do you make sure that the mirror server have all the new data that was updated in the 1st server’s DB, do they have like shared DB or something, and how..
Any other information, links, or suggested hosting sites for reliable dedicated server (with big bandwidth) would be greatly appreciated.. thanx
P.S. We use PHP/ MySql technology.
Well I am looking to learn to manage a server (so I won't need to hire others to do what I can do). However I have some basic questions.
1) So lets say you have a server with two identical HDD's and raid 1?? or a SATA controller so that the second HDD is just a mirror of the first HDD when/if the first HDD dies does the SATA controller or RAID card see that the first HDD died and switch to the second HDD so the site that is hosted on the server stays online?? I am thinking yes as that would seem to be the point of having a raid or sata controller and setup ??
Part twoto the question is is their software that you need to install that will make the server email you when/if a HDD dies (so you can do pull the dead one out and replace it with a new one). Or is it just that you would watch some type of server log(s) to stay ontop of if the server is running all good??
Second is how common (these days) is it for a server that would be new and brand name have a HDD die or have some other hardware failure?
A great insight to alot of my research and thank you in advance for any advice given.
I have a server based in HK(with WHMCS) and host several websites. The speed and availability serves the Asia Pacific market/viewers well; but we have several new websites that also targets the European and North American viewers.
I have been researching on getting a dedicated server based in US to mirror our server. Therefore allowing the US/European market to access the website faster. Although we have a few problems (and very little budget to solve it too ;p)
1. We need to sync the two servers in real time ; rsync seems to be the best but is there any other reccomendations?
2. We will make the IP address in each servers the same, so our clients need not change their dns. Do we need IPcast/anycast?
3. Is there anything else that I may have oversight?
