DPM DISK BACKIUP
Posted on 2011-02-21
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
