Hello,

I have a windows server. Recently that crashed & I couldn't recover it. I used windows back up but it failed. One of my friend said that it is possible to get backup image & restore using redhat linux.

If it is true, I need a link that I can assure our higher authority to go for another Linux server.

Kindly give a feedback.

You may not need that extra server, unless you mean as a DR replacement for your current servers.

Investigate 'clonezilla'. It can back up, restore, deploy entire servers by image. If you need it for only ONE server, it can run from DVD media. All you need is adequate network storage to save the image(s) it creates.
(And, in a DR situation, a server to restore onto.)
There is also a server version (SE) that can site on your network and image multiple servers, even at the same time. For that you need that extra hardware (with lots of drive space).

Know that even if the hardware match is nearly PERFECT, your Windows is likely to need reactivation. Even a restore to an early point in time ON THE SAME HARDWARE may trigger the Microsoft License bug. Alas, the only way to really fix that is use Linux servers and get away from Windows, and I am not recommending that at this point. (Not that it cannot be done, but clearly your company is not ready for that.)

My company uses Bacula, but frankly clonezilla is a better answer for DR recovery. Using both might be a consideration.
( Because you only think you can have to MANY backups if you have never NEEDED one! )

We're happy to help, but not sure what you're thinking we can tell you.

First, if your 'friend' tells you this, why don't you get that friend to give you details about how?? Secondly, just saying "it failed" says nothing about the problem(s) you had...could be they will follow whatever backup method you use now, regardless of platform. You also just say 'Red Hat Linux'...but not what version. You are aware that RHEL is a product you have to PAY FOR, right???? Have you called Red Hat to ask, since you're paying for their support and access to their knowledgebase?

And you say "backup image"...if you mean a TOTAL system image for a Windows server, good luck. Windows will need to 're-verify' the license if you change hardware even SLIGHTLY, much less try to restore to a new machine. Which is a Windows problem...and this is a Linux forum.

The best thing you can do is to back up your DATA ONLY to whatever external media you choose. If your system dies, restore the operating system from scratch, reload your programs, then copy your data back over.
