    Hi LBD

    What I meant is I image to protect me against hardware failure. Any other software type screwup, I should be able to fix with Rollback. So if I have to restore an image without a hard drive failing, it means something has messed up very very badly.

    @Pete

    Yes thanks I got that part
    :Acronis for image back up
    :Rollback for instant recovery

    What I'm not sure about is how the two go together on the same box?

    There are multiple posts about this MBR conflict/rewrite

    So the question was "how are you using both on the same box?"

    Thanks.

    Read the the knowledge base/faq on the Rollback website. The only issue is if you do a restore over an old system, you may not be able to boot the system until you run FDISK/MBR. Other than that it is use Acronis as usual with Rollback installed.

    The Rollback Rx web site states

    so how is that supposed to recover to a specific state?
    What does the program do?

    Howard. It's all done by magic:D If I understand right, lets take one file abc.doc. It exists in the current snapshot I am working in, and Rollback has a map of the sectors containing this file. I take a snapshot call it one, and it stores the map of the sectors for abc.doc. Now I edit abc.doc and save it and a new index is created of the sectors where the file now resides. Lets take another snapshot and call it two. Now if I restore to snapshot one, then the index for abc.doc is the index of the sectors when I took snapshot one, hence the original copy of abc.doc. The sectors containing the edited version are associated with snapshot two, so you don't see them in snapshot one. On the other hand if in snapshot two, I delete snapshot one, then the index too the original version of abc.doc is gone, hence the file is gone.

    Make sense?

    Did an interesting test. Loaded a 500MB file from floppy to my drive. Then took a snapshot and in the new snapshot deleted the file. In either snapshot if I checked disk properties of Drive C the space used was the same. But if I looked at the disk map in Perfect Disk, while in the snapshot I loaded the file into, I could plainly see the data in use, but going to the new snapshot I couldn't see it even though I new the data was there.

    Some how the index system of Rollback is smart enough to know those sectors are in use.

    Very clever program.

    Sorry Peter maybe I am misunderstanding you but this is what is posted on the Roolback site as well as what support told me a few weeks ago.

    http://www.horizondatasys.com/piece.html?piece=knowledge_base

    "Do I have to take any specific actions with Rollback Rx before I make or restore an image of my hard drive with programs like Norton Ghost or Acronis True Image?
    You have to do the following: Uninstall Rollback before restoring a disk image. Run FDISK /MBR from the command prompt after restoring a disk image. Because Rollback is in MBR, the drive image software "Ghost" and "Acronis" do not reset MBR during cloning."

    Again maybe I misunderstood you but I wanted to make sure people know they have to uninstall Rollback Rx before they can restore a disk image. Just saw this thread again since the post from lynchknot brought it to the top.

    Thanks,

    Chris

    Hi Chris

    You are correct. If I understand it right you can image with Rollback installed, but must uninstall if you restore. That obviously wouldn't apply in the case you are doing a bare metal install with a new drive.

    Yes. You can create an image with Rollback Rx installed, just not restore it without uninstalling Rollback Rx.

    Thanks,

    I have few question about Rollback Rx,
    Suppose some body is having multiple OS on his PC, say XP, 98 and Linux. Will Rollback work in this state. If so, which OS it will protect.
    It can peotect from all sorts of Viruses etc.?

    @Pete & Chris: default techies for Rollback:D

    So here we go again

    The Acronis image will recover the disc after Rollback uninstalled: OK

    Doen't that defeat the purpose of the imaging app (ATI), as, I imagine in the case of unbootable crash, would have to go to Acronis boot disc or other and there would be no chance to uninstall Rollback in those circumstances.

    Head spinning in Sydney

    This is a good thread
    Horizondata.. should contribute eh?

    Regards

    When you say unbootable crash I assume you mean Windows wont boot. If this is the case Rollback Rx works before Windows and therefor you can recover to a previous snapshot that does work. Also you can remove Rollback Rx if you should wish the same way before Windows even loads so either way is not a problem.

    Good thread yes. Horizondata can not really continue as this would be against what Wilders recently announced and that was that tech type support/answers should be discussed either email or an official vendor forum. Something similar to this anyway.

    Please feel free to ask more I'll be up for a bit.

    Thanks,

    Chris

    Lost me

    How can Rollback work if cannot boot into OS
    (possibly revealing lack of finer understanding of things there!)

    Where does it start?

    To Create Disc/Data Safety option ie use ATI or Ghost or other for disc clone/image in case of Complete HD failure I am thinking R'back needs to be uninstalled.

    SO then:

    what happens to this miraculous snapshot setup?
    Can the disc imaging apps cope with any residual R'back data?
    Are there potential problems with uninstalling and reinstalling R'back say once a week for cloning/imaging.?

    Getting there inch by tortuous inch :blink:
    Regards.

    Rollback starts after your BIOS but before Windows. There will be a screen displayed for just a second or so that allows you to hit the 'home' key to enter Rollback Rx. You can also take snapshots and start a restore from inside Windows.

    When you say complete hard drive failure I'm not sure what you mean. If there is complete hard drive failure I'm thinking a new drive maybe needed not uninstalling Rollback Rx and then reinstalling TI image. Can you clarify?

    Snapshots are gone when you uninstall. I can only speak for ATI when I say that it had no problems on my system when I uninstalled Rollback Rx to restore an image. As for potential problems just as I stated above that you will lose your snapshots.

    You really should test Rollback Rx before you purchase it if you haven't already. It will give you a good idea of how it works. If you don't like it just uninstall it. Just suggesting...

    Thanks,

    Chris

    Yes hard drive failure; catastrophic loss

    Unless there are some quirks in R'back not yet seen, then there would seem to be little need for other imaging software "in the box", but, I accept the need for and would have a second strategy available.

    So we (I) then seem to be left with the need for "off the box" images or disc clones for recovery in event of HD failure. Although I seem to be seeing that reinstalling a clone or a disc image to a new disc is not always clear cut!

    Am I getting there?

    Exe for R'Back and ATI sitting there just waiting for the finger to click.

    Regards

    I agree a secondary strategy is good. I mean if hard drive fails Rollback Rx will not do you any good.

    Not sure what you mean clear cut. You mean because of uninstalling Rollback Rx in order to restore an image using ATI? If this is the case really you shouldn't have to do this anyway because you would use Rollback Rx to restore back to original state. Only if Hard drive fails can I really see you having to restore an image using ATI.

    That you are.

    Thanks,

    Chris

    There is no way to preserve sectors that are no longer part of a file, they will, at some point, be used for other files.

    My first sassy answer is you are right Howard, the program doesn't work. But you are making an assumption based on knowledge of the windows file system. They are essentially replacing the windows file system with their own indexing system. If you read the web site you will note they say using defraggers such as Perfect Disk, while it won't hurt anything won't help that much anymore, since Perfect Disk can't see their structure. That has been my experience.

    Watching the files with PD without Rollback, and can see changes from day to day. Once Rollback is installed then watching with PD you will see very little change in terms of fragmentation.

    Also I will repeat, with FDISR, when you add lots of data, and then refresh a secondary snapshot you see the data in both snapshots with PD. With Rollback you only see the extra data in PD when you are in the snapshot that contains the data.

    Howard, care to explain that?

    I did not understand Rollback at first and my many questions at Wilders, when we all first discovered Rollback, shows this. Not until reading the ENTIRE owners manual twice, and reading BOTH the faqs and knowledgebase a couple of times each, did I begin to understand this program. Its those patented, advanced and complicated algorithms that do all of this "magic". :cool: Throw much that you know about files, defragging, and backing up away with Rollback. This strange creature really does force you to "think outside the box".

    Boy you hit the nail on the head. What's really scary is when you realize you might actually understand what is going on.:D Doggone thing does indeed work though.

    Of course, I also might have understood RB a little quicker if I actually had the darn thing and was using it, using something is usually the best way to learn, but like I said elsewhere, "If it ain't broke ..."

    Achtung Acadia!!! Do you haff relatives living in Chermany? Ve have vays to MAKE you buy das Rohlllllback-schnitzel.:ninja: :ninja: :ninja:

    Chust kidding. Seriously folks, it's getting difficult to find Rollback posts because there are soooo many different threads here at Wilders. Could someone -- a Mod, anyone -- consolidate this schtuff or otherwise instill some order here (please)?

    Also, I thought I saw somewhere that the Rollback site would start its own forum. I searched the Rollback site to see if they have one, but I couldn't find it -- but then I need GPS to find my way back home from the local supermarket. :blink:

    Is there a Rollback forum? If so, where?

    Hi Bellgamin,

    There is no official forum of Rollback RX for the moment. From what people of Horizon datasys have told me, they are working on a new website wich will include a forum and will be launch in a few months...

    At this time there is no forum for Rollback Rx. Of course besides these disussions here.

    Thanks,

    Hi Guys,

    I have recently been putting FD-ISR through its paces, to see how it suits my needs, and I have also recently come across this thread about RollbackRx, which I have followed with interest.

    I would now like to chime in, following an online chat I have just had with Horizon Datasys. I must say it was a pleasure chatting with a support pro who didn't simply use canned responses. With Horizon's permission, I reproduce the whole chat transcript here (warts, typos and all, and missing the embedded smileys), as I believe it adds some clarification to issues and questions raised in this thread. I have changed the name of the Horizon DataSys support person to honour his privacy. They don't really have someone called Urquhart :)D)...
