DPM DISK BACKIUP

Hi all,

I'm looking for a way for fast and reliable backup.
We have a Hyper-V server with 3 Virtual Machines.
1 linux database 1 mail server Excn2010 1 terminal Server.
We have 2 seperate Domain Controllers
We have 1 ISA server
and we have 1 Camera server (security data storage)
Then some pc's wich function as a server for plc deveices with some data on it.
and the 18 clients  XP-PRO SP3


The clients don't really need te be backup up.
The rest is.
At the moment we have a LTO3 tape wich basically backups up only 1 DC and 1 EXC server
Being the most important this is around 400GB data. Via tape it takes like forever to do a full backup. (around 15 hours)
Also 3 weeks ago the raid controller of the mail server died and building the restore exchange took more then 8 hours.
This is to much for our company.

So, we are looking for a new way of backing up.

The first problem is tape backup itself takes to long. Users are starting to work again after 6 hours. So a full backup can only be done in the weekends on Saterday night.
Differential backups are done thrue out the week.
But in case of a restore we need all the TAPES for a restore.

The second problem is we need to backup alot more then only the exchange and DC.

So I was looking for a new way of backup.

Any advices here?

I was thinking of a raid 0 of 4 disk around 640GB this with a mirror raid 0 4 disk 640GB
The install win2008 R2 on this "storage beast" and install Microsoft DPM. (system centre)
Can I make full backups at greater speeds then the tape can do?
is it a safe way of backing up?

Then I need to store the DPM recovery points on to tape during day.
Can this be done?
Will there be an option to use later on a bigger storage san?

Or would it be better to install DPM on de the Hyper-V server and build a SAN ??

What would be best?
Other Idea's also welcome

From a cost stand point, I would think BE 2010 would work. This allows you to perform image backups of virtual enviroments and bare metal restores if you have physicals you wish to back up. You could backup to USB drive, which have their own issue, even with BE, or make B2D folders on a small, low cost NAS.

Thanks for your answer but BE is out of the question. We had BE and it also has it flaws.
Not fast enough. Support isn't always what we needed. So we left SYM BE 2 years ago.
Also low cost NAS. Is't this some tricky. We have thousends invested in great servers and virtual machines and in the end we trust our backup to be on a low end nas or external harddisk?

We need a rock solid solution to backup easy and restore in a swift.
The price isn't much of an argument since not having a backup wich works ultra good is lost time in case of restore. This wil cost more then investing in a full and good backup solution.

Well, it is more pricey than BE, but last year I deployed EMC's Avamar. I have a review of it here on EE. I use it to backup VM's, Exchange, SQL. It is licensed based on the amount of storage space on the grid, so you receive unlimited client licenses. It performs data deduplication on the host and the grid. I backup over both LAN and WAN.

Optimizing Cloud Backup for Low Bandwidth

With cloud storage prices going down a growing number of SMBs start to use it for backup storage. Unfortunately, business data volume rarely fits the average Internet speed. This article provides an overview of main Internet speed challenges and reveals backup best practices.

Ho much is pricey? Are we talking hundreds or thousands? Just to take an aim could you roughly say how much?

It really depends on the total amount of data you are backing up. That determines the price. We purchased two 23TB grids (on sits at our DR site) for $280K. It is priced on TB of storage needed, plus the data is de-duped, so you don't need as much as you actually have on hand. EMC has tools to determine how much storage you need.

Okay, *swallow* that was a bit out of my league.
As I only have around 400GB of critical data and 750Gb in total that would be a little TOO expensive for us.

Yes, but that was for two 23TB grids. I don't know what the price per GB is. You would need to contact EMC and they would be able to give you a price based on your needs.
