How to use Acronis to backup o/s ?

wrote: OK, I think this is the point of confusion. If one uses Casper to clone a source drive with say 3 partitions over to a destination drive, it is a bit inaccurate to say "you can clone those three INTO an existing partition on the destination drive". Because what is really happening must be this: when Casper (or any such program) starts cloning TO the currently existing partition on the destination drive, that existing partition is destroyed (marked as unallocated, behind the scenes), in preparation for the cloning of the 3 partitions. How does that change anything?? If the resulting partition is the same size as it was created to be before the cloning operation and contains the clone of the source drive afterwards, I don't care if it changes the partition into a pretzel before making the clone. All I care about is that it contains the clone and that the clone is usable for restoration purposes. It can be a partition that is either smaller, the same size, or larger than the size of the source drive, as long as it's large enough to contain all the data on the source drive. Which will be the case. |

I apologize. You are 100% correct. I am SO embarrassed! Let me backup... As I've said in previous posts, I use Casper on a daily basis to clone disk-to-disk so that I have a bootable backup for my system disk. I have ONLY used it that way. I've relied on what Anna has said - or what I *thought* she said - to talk about other uses. I shouldn't have talked about something I wasn't completely sure about. Either I read wrong (she is so damned verbose that she's hard to follow) or she posted bad info. Whatever. I ended up propagating bad info: that the 3-partition disk could be cloned INTO a preset partition on another disk. IT CAN'T BE. I just finished partitioning my system disk into 3 partitions and I copied some data into each of the extra partitions. I then partitioned one of my other internal disks into 2 partitions. I tried to clone the 3-partition disk to one of the partitions on the other disk - ain't gonna happen. Casper wants the entire drive as I originally thought it would a month or two ago. To keep Casper from using the entire drive, I had to use Casper to reduce the size of each partition on the source disk prior to performing the clone. RESULT? The recipient drive has 3 partitions AND a lot of unallocated space which would be totally useless for holding another Casper clone. WHICH APPEARS TO MEAN (as I've claimed in the past) that one can NOT have multiple complete backups using Casper without having multiple disks to hold them. If one wants multiple backups - and most everyone here except Anna seems to feel that's desirable - an imaging program such as Acronis True Image would be required. If one is merely cloning a partition, then that limitation doesn't apply. I hope I didn't miss anything, because I'm gonna crash for the night. Again... Bill, I apologize. Richie |

Short version: Casper wants to use the entire drive, or at least enough of it to hold all the partitions and all their data... meaning that the partitions can be shrunk - if desired - but not smaller than the data each holds. When cloning is complete, the drive will either be fully used, or - if the partitions were shrunk prior to cloning - there will be unallocated space. |

Using your example with a source HDD of say, 250 GB, containing three partitions -let's say a C: partition of 50 GB, a second D: partition of 125 GB and the third E: partition of 75 GB. Now let's say the user has a 500 GB external HDD which will serve as the "destination" drive, and (for whatever reason) he or she has created two partitions on that external HDD - one of 300 GB, and the second as 200 GB. Using Casper it is a simple straightforward procedure to clone the source HDD containing the three partitions to the *first* partition (300 GB) of the external HDD, in effect a disk-to-partition clone. As I've previously indicated, the only proviso is that the destination partition be sufficient in size to contain the cloned contents of the source disk. Since the user would be cloning a 250 GB disk to a 300 GB partition on the destination drive there is obviously no problem here. Following the cloning operation, the destination partition (the 300 GB one) will now be split up into the *three* partitions of the source HDD. Since the user would be cloning 250 GB of data into a 300 GB "space", (in effect a disk-to-partition clone), the program will automatically *proportion* the three partitions that will make up that formerly single partition. So that in this specific example three partitions will be set up in that former single partition as follows: 1st partition (the former C: partition of the source HDD) = 60 GB 2nd partition (" " D: " " " " " = 150 GB 3rd partition (" " E: " " " " " = 90 GB The upshot of all this is that now the external (destination) HDD will, contain four partitions - the three partitions from the source disk (above) and the 300 GB partition (untouched) previously created by the user. Please keep in mind that the drive letter assignments on the *external* (destination) HDD are of *no* relevance should the time come when the user would want to restore his/her system from the contents of the destination drive. Obviously should the user desire to restore their system to its previous state, they would simply clone the contents of (in our example) the first three partitions on the destination HDD back to their internal (source) HDD. (I mention this because it seems there is some confusion over this point among some users.) But also understand (for restoration purposes) that there would be nothing to prevent the user from making a *disk-to-disk* clone from the external HDD to the internal HDD as long as the internal HDD (acting as destination drive in this situation) was sufficient in disk space to accommodate the contents of the external HDD. And, of course, nothing to prevent the user from making a simple partition-to-partition clone should he or she wish to do so. The process, is as I've stated, simple & straightforward for the user to achieve. Little more than a few mouse clicks with the Casper 5 program. Hope this helps. Anna |

So, the answer is: The detination drive will have one partition, which is unchanged, and three new partitions where the other one of two once was. Got it. I still think that the main appeal of cloning is that one can simply physically place a perfectly cloned drive into the PC that contained the original drive, which for whatever reason can't or won't work anymore. Or if the cloned drive is *already* connected and "in the loop" (as another internal PC hard drive or a connected eSATA drive, which also functions as an internal drive), then it's just a matter of using the boot menu to select it. Cloning a clone back to the original drive (or a replacement drive) -- for instance, the clone resides on an external USB hard drive -- doesn't seem to me to have much of an advantage over restoring an image. Is it quicker, perhaps? |

We have a problem he Anna's info does not jibe with what I found last night (actually early this morning) when I put it to the test. Casper ONLY SAW THE ENTIRE DESTINATION DISK, not the partitions. However... the destination disk was smaller than the source drive, not larger as in her example. Maybe that made a difference, but I can't see how. Casper readily sees entire disk that are smaller than the source disk and will shrink everything proportionally to fit the destination disk. Casper DID NOT SEE the two partitions I created on that destination disk (each large enough to hold the partitions/data that needed to be saved), it only saw the entire disk. I still think that the main appeal of cloning is that one can simply physically place a perfectly cloned drive into the PC that contained the original drive, which for whatever reason can't or won't work anymore.

Is it quicker, perhaps? You have rightly identified the largest drawback of using Casper: it can only clone. Restoring from the clone is no faster than restoring from an image. PLUS... if you need to boot to a CD to perform the restore - a very likely possibility - you better have bought and downloaded the burnable ISO image to do that because it isn't included in the main program purchase. |

P.S.: Acronis also will clone your disk if that's what you decide to do some day. SO... one gets both cloning AND imaging utilities with Acronis - and MORE. It will backup - manually or on a schedule - entire disks or just selected data, even a single file. And you can browse any image to find selected data to restore if you don't need to do a full restore. Try doing that with Casper. I'm not totally trashing Casper as a program because as I've repeatedly stated: I use it daily. But ONLY to maintain a clone that is second in the boot order in case my system disk totally dies. I also use Acronis on a daily basis to image that drive for use in the case I need/want to do a full/partial restore. Richie Hardwick |
