I see no point in that. The point of me cloning it was I could actually put the backup disk into the machine if the internal disks had blown up, and it'd boot off it. If that's not possible, then simply copying all the files using xxcopy is fine. What use is one big image file to me? You're not limited to clones OR images. If you have spare drives, you can have one or more clones AND one or more images. Clones have the advantage when you want to be able to replace a failed drive by plugging in the clone, then boot and be on your way. That's extremely comforting and I fully understand why you want that. Images have the advantage in that a single drive, if it's big enough, can hold lots of images, and any of those images can later be burned to an empty drive, thus creating a 'clone' that's current as of the date that the image was created. Clones are more convenient and less efficient. Images are more efficient and less convenient. Take your pick, or choose a mix of both. Whether you go with clones or images, it's easy to reach in and pull out specific files, so that's a wash. The trouble with image files, is you rely on having the software there to read the file. And a corruption can lose the whole thing. Maybe you could add some parity blocks to the archive (QuickPAR) ? https://en.wikipedia.org/wiki/Quickpar ******* I've had a couple Macrium .mrimg files, where I ran a "Verify" over them, and they failed. The file in question, might have been around 1TB or so (Macrium output can only go up to 2.2TB). So damage does happen (even if I cannot figure out where the damage is). VHD files can be read by multiple utilities, but I'm not aware of any utility that offers "repair" for such. As far as I know, that's just a block-level storage scheme (so the blocks are in a way, independent of one another). There might be some bad error multiplication, if a chunk of one of those was bad. The original Windows 7 System Image uses VHD. The same backup feature on Windows 10, uses VHDX, and that format cannot be read by 7ZIP. To convert VHDX to VHD, takes a Hyper-V installation (as then, the utilities in Hyper-V would work for you). Macrium has its own built-in converter, which converts a captured MRIMG into a VHD file. I have my own block compressor for sector-by-sector images, but I cannot recommend that either. If my compression symbol were to go missing in the stream, the result on the output would be "huge" :-( My compressor comes with both input and output checksum, which allows me to detect if anything has changed, between backup and restore. I can run a restore process to NUL if I want, and then just use it for "Verify", without needing an actual verify command line option. The bottom line - use a PAR scheme. At least one of the PAR schemes, is not mathematically sound. It could recover archives "most of the time", but because the math wasn't robust, some people were occasionally finding situations where it wasn't working (numerical sensitivity). You want to review what's known about that, before selecting your flavor of PAR. That was a long time ago, when it was screwing up, and I haven't played with that in years. I guess my solution, is to create more than one image. And use "Full" rather than "Incremental Forever" or similar. It takes me all day to do backups, so running a Full on everything, doesn't happen that often. Good luck with your PAR research. Paul I just copy them straight over, file by file.

"James Wilkinson Sword" wrote You really need to do some research and not just expect software to do it all for you. I can do it myself with xxcopy in a command line. If the software isn't better than that, it's useless. If you're trying to clone to USB sticks that might not work. No. If you just mean a USB-connected hard disk, that should work. Yes. 256GB SSD mirror and 3TB HDD mirror to 3TB HDD USB. But you don't clone to a partition. You clone to free space, which has no sector size. It does. There's a physical parameter of the drive which recently changed from 512 to 4096 or something like that. Most cloning software can't handle that. Cloning means copying the entire partition, bit for bit, to another location and/or disk. (Usually it's cloning for whole disks and copying for partitions, but it boils down to the same thing.) I know. I've done it since about 1995. | The trouble with image files, is you rely on having the software there to read the file. And a corruption can lose the whole thing. Disk images are for OS backup. You get it all set up, install the software, then make a disk image. Then your backup only needs to be data files that have changed. When you lose Windows you restore a fresh image and put back your data from backup. That way you never have to slog through installing Windows again and don't have to reinstall software. That's the point of my analogy to a tractor trailer. With images you just swap out the tractor and you're back on the road. The cargo shouldn't be stored in the tractor (Data should be on other partitions than C drive) if you want disk imaging to be a good solution. Too much hassle. I just backup everything every time. If the whole computer fails, I reinstall the OS, then copy things back from backup. More likely, some things got corrupted, and I just copy the damaged files back. Some software now allows you to extract files from images, but that's not really the point. If you need to extract a file or two then you don't have proper backup and, as you say, there's little point in having the images. Constant syncing also misses the point, as connected backup may be destroyed when you lose Windows. Your method of copying everything is wasteful and clunky, but it's better backup than nothing. The hard work is done by the computer, not me. And I can't miss anything. Yet if you lose Windows your backup does little to help. The clone would, which is what I used to do. All I have to do now is reinstall. It's the data that's important. Reinstalling OS and programs is simple. You'll still have to completely re-install Windows and all of your software, because you don't have disk images. If that's OK then go ahead and use copying for backup, but there's no point backing up Windows system or program files. There is, because there can be settings in there. And it's easier not to bother omitting things. If you manage to actually do a partition copy of C drive that's bootable then you have pretty good backup there, though you'll still need to back up changed files. And you don't want to keep messing with your clone, or updating it, because that risks corruption if the files you update it with are corrupt. (That's another reason for disk images. They represent a fresh install rather than yesterday's setup.) I used to alternate a few clones. Using an old clone with out of date everything is pointless. I think part of the confusion is that disk utilities have blended with backup products, creating bloatware for people who don't know how to back up *or* manage disk partitions. So you pay for something like Acronis or EaseUs and end up with an overblown system of images and synchronized backup, which is still vulnerable to something like a power surge. Those products do a lot of hand holding but reduce efficiency in the process. There is no correct way to do backup. There are different approaches and to talk about it you need to understand the differences. There's also online backup. Yeah, like I want my files under someone else's control.... I know a tech support person who makes all his customers pay something like $70/year for Aconite. Aconite backs up all their file changes remotely. That's an easy solution if you don't want to deal with the details. If Windows gets lost you just restore from the Aconite server. It's also easy for tech support. He doesn't have to make an emergency visit to restore his customers Windows install. He just runs Aconite. Maybe he can even do that remotely. The disadvantages are cost, loss of privacy, and the fact that you're depending on a commercial entity to protect your data. They could go out of business and leave you with no access. It's a solution that's mostly just good for tech support, because they can't get away with charging for $800 labor to restore a computer worth $300. -- I never wanted to believe that my Dad was stealing from his job as a road worker.

Ken Springer replied: In the usa, in a big box store, it's Windows or Windows. Not technically true. :-) Best Buy has a Mac section, and sells Chromebooks, which is based on Linux. Microcenter stores, at least the one in Denver, Colorado, USA, has a Mac section. Just an FYI. Yes. I know. I didn't have the legal words to caveat out the fact that there are Apple devices (which, of course, come with another OS) and there are Google devices (which come with a different OS). But if it's a "PC", it really "can" come with one of three realistic OSs: 1. Windows (usually the latest at the time of manufacture) 2. Nothing (this is what I'd prefer, personally) 3. Linux (of which there are many, but Ubuntu would likely be #1) I wonder how many people remember that "PC" started out meaning "Personal Computer", the OS didn't mean anything. That's the primary way I still use PC. If I want to be specific, I say Windows. :-) I wish X86/X64 PCs came with nothing, personally. That would drop the cost by (I don't know) maybe 100 bucks (I don't know what the cost of the operating system is when done this way though). And, for the thirty-cent price of a Ubuntu Linux ISO dvd disc, I could save that hundred bucks (or whatever) and load the Linux on there. At this point, Linux does everything that Windows does, within reason, in that the only thing that won't work native on Linux that you really need is Microsoft Office. (Yes, I'm completely aware of all the office alternatives, but you have to interact with the rest of the world also, who uses Microsoft Office. And, yes, I'm completely aware of Windows emulation such as Wine and Windows VMs such as VMware although I've never used them myself). Or, you could move on from Office formats and use the PDF format. Then, for the most part, it doesn't matter what word processor, spreadsheet, etc., that you use. Access would be a hiccup unless you are just sharing reports. Granted, there will be times when Office is needed, but it's no longer a given if you are willing to move forward and change. So, I would just like to save my hundred bucks and install Linux off a thirty-cent disc, and I'd have a perfectly good operating system, without all that Windows 10 touchscreen crapware just making a mess of things. One thing I'm considering for this, is a visit to a local pawn shop. Personally, I don't need to own a brand new machine. PS: I probably should not have said the above in this ng, so, please don't respond viscously. I apologize in advance for my hatred of the Windows 10 menus. -- Ken Mac OS X 10.11.6 Firefox 49.0.1 Thunderbird 45.7.0 "My brain is like lightning, a quick flash and it's gone!" |
