Hello, firstly is this is simply a copy of an existing thread please don't hesitate to redirect...
I currently have a single HDD with everything on it; OS, music, program files etc and with my laptop drive recently failed am keen for some redundancy. I think RAID1 would suite me best as I feel I can just set up and ignore until anything goes wrong.
However, I don't have the ability to back up the drive and don't want to lose anything on the RAID setup (which I have heard I will). Is there a way of adding a second drive without losing data?
I currently have:
1TB Seagate Barracuda ST1000DM003 1 Terabyte 7200RPM HDD
Gigabyte GA-970A-DS3 motherboard (which supports RAID1)
Windows 7 Home Premium
RAID is not a backup. A RAID 1 is a mirror. It has a duplicate of everything on both drives. It also faithfully mirrors accidental deletes, corruption, malware, viruses, etc.
Any company that uses a RAID setup also has an actual backup.
Instead of a RAID setup, I'd suggest 2 parts.
An image of the current drive. OS, applications,a ll of that
Then a daily (?) copy of your documents. Whatever is new or changed, copy to a different drive.
Update your image weekly, or whenever you add a new application.
Use something like SyncBackFree to copy over your personal documents.
For a whole disk image - There are many imaging applications. CloneZilla, DriveImageXML, Macrimum Reflect, TrueImage.
Copy an image elsewhere. In case of need, that image can be restored to a new drive.
As for as doing it automatic on installation of a new program? Personally, I would not want that.
I install something, it sucks, I uninstall it tomorrow. Needless writing back and forth. And after you have your basic toolset established, how many new programs do you install? Just run that whenever you think you might need a new copy of the image.
For your documents, the mentioned SyncBackFree will do this on schedule. I have my "Libraries" (and other things) scheduled to copy to a different PC every morning at 2AM. Or weekly. Or whatever schedule you want.
