That is correct. Since I multi-BOOT with Windows, I image the Linux side of the System while I'm running in Windows. Otherwise, Rescue Media is the only way.
I'll probably do the same, but when I ultimately abandon Windows (which I plan to do on both my desktop and laptop), it would still be nice to be able to do hot backups!
Without a sub-System like VSS on Windows, this is almost impossible to do without special drivers (which is what the original imaging people did with Windows prior to VSS). There is no similar function under Linux (LVM partially accomplishes similar tasks), although they've messed around with it from time to time. Without being able to freeze that FileSystem (required for stable, accurate HOT images), the image could be very unreliable for many filetypes as well as the FileSystem itself.
I think the Linux Devs are working on a feature similar to VSS. BTRFS will probably be the future of Linux snapshotting...
Frog, are you aware of this? -- it's way over my head!
It's actually not too far over your head, Scott... it's more of a Linux MOUNTED volume vs a Windows LOCKED volume apples to oranges scenario.
The app states it cannot, reliably, snapshot a mounted read/write volume which is exactly the same in the Windows environment without VSS or a special supplied driver by the app author (IFW/phylock or Reflect/pssnap). It can easily perform that function on any unmounted volume (it's not changing if it's not mounted... aka "unlocked" in Windows). The ability to snapshot a LVM (Logical Volume Managed) volume has the shortcomings of LVM in general... there can be issues.
There's another app from R1Soft called SERVER BACKUP MANAGER that can snapshot a mounted read/write Linux volume. It does so successfully because it does supply its own special driver (like Reflect & IFW do if VSS doesn't exist). I believe it also works in the Windows environment as well.
All the snapshot apps that run without VSS, even with their own drivers, cannot guarantee the consistency of many of the databases used in either of the OS environments. VSS has the ability to "warn" database apps (if they register themselves to receive that warning) about an upcoming FileSystem freeze which allows those apps to make their databases "consistent," usually by flushing all their high-speed DATA caches out into the database file itself, making it now consistent.
Accurately backing up consistent LIVE FileSystems is not an easy task for any application in any OS environment. That's why COLD IMAGING (hello @oliverjia ) is always accurate and consistent... the volumes being imaged are never Mounted/locked/in-use in any way other than in the imaging operation itself (no changes going on).
Gotcha (I think).
By the time you get to Linux full-time (I will be running a Windows VM under Linux just to run those pesky apps I really need that don't exist under Linux), there should be alternatives available for HOT imaging, maybe not as efficient as Reflect when it comes to restorations but at least as efficient when it comes to imaging.
Well, I'm now looking at live Linux distros on my old XP desktop to see which are light enough to run as fast as XP, or faster (and hopefully, Windows-user-friendly)! Once I find the right one I'll replace XP on that desktop so I guess I'll be doing cold backups with either MR or IFL.
I probably won't be installing Linux on my laptop until 2020 (end of support for Win7). Win10 is definitely not in my future!
Can someone please tell me my ReflectMonitor.exe seems to use a lot of memory even though there is no scheduled backups? (all backups done by booting from USB recovery media) It seems to increase in memory use memory use the longer the PC is not rebooted or shutdown. My PC is on 24/7 & is only restarted if needed by windows update or anti-virus program update. T the moment it is using 1.4gb of memory.
This could be a sign of memory leak in the program. Is this behavior being consistent even after a system reboot or at least restarting of the application?
Yeah if I reboot the system the memory use of ReflectMonitor.exe is about 3mb, the longer the system has been running the more memory that process uses, I have seen it as high as 3gb. If I end task that process it restarts & uses about 3mb then it increases the system is up. Screenshot is taken after ending the process & it restarting itself.
I have seen several reports of similar behavior from the program, I think the only solution is to contact the developer and provide logs to go through the issue to get a possible fix.
You could also try adding it to your antivirus exclusion list and see if that makes any difference.
Also from task manager, in 'Details' tab, from menu 'View' show: memory commit size, non-paged pool, see how much it goes up for reflect process.
Will try your suggestions, it's annoying me as I used the free version for a year or two with no issues, I then got a good deal on a 1 year license for the home version & that's when this issue started, the free version was fully uninstalled then a reboot before installing the new v7 home version.
Has anyone installed Reflect V6 Free on a tablet?
I just had the auto update from W8.1 to W10 on the tablet and I'd like to make an image, nothing more, no incrementals, no schedules, just bare bones imaging of the W10.
Can I download not only the "installer" to my main PC but also download the full app to my main PC and then copy the full app to the tablet to install it?
Edit: I tried running the installer on my PC and found that it would download and install the main app on my PC so I have to run the installer on the tablet. I guess the worst case would be that Reflect won't install on the tablet but won't trash the tablet in the process, I'll give it a try later today.
A new update has been released, version 7.1.2885...
Updated using internal updater. Download was 43,8 MB in size.
You are most welcome ...
If I wish to restore my Windows partition which in on a GPT disk using the Macrium recovery installed on a USB drive, do I need to boot the USB in UEFI mode or does it not matter?
It doesn't matter. As long as your machine can successfully boot the rescue media into the rescue environment, then Macrium can do its job of simply writing the imaged partition to the destination. Hopefully, you used the option when creating the rescue media to prepare it for booting BIOS or UEFI either one - then it's even less of a question.
Thanks. And yes, I did create the rescue media for booting both BIOS and UEFI
With Windows UEFI booting you should have CSM disabled. Then you won't see Legacy/MBR choices in the Boot Menu.
I leave the CSM (Compatibility Support Module) in the Bios settings on Auto, so if i do have a bootable mbr disk or usb device it will be selectable on boot overrides. on a macrium restore if you are restoring from a mbr image to a gpt/uefi use the advanced option to deselect rewriting the imaged mbr back to the disk. same on visa versa...
Hi Guys, Soon I'll switch 1 tb hdd and move to 512 gb ssd. I have the latest paid Macrium, does it matter, choice of "Image or Clone" for the transfer. I understand that image is one big file, and expands, so as to be the same, as when imaged onto the new drive. Some say it does not matter, others say Clone.
Which ever one used I plan to transfer all, existing partitions to ssd. The 512gb ssd will be 10 - 20 times, more storage space, than the transfer. Depending on clone or image used for transfer, can i easily assign all non used space to (c using clone or image.
I've used Macrium image to restore & every no & then practice, restore on an old laptop
Use Clone. After the cloning operation is complete, shut down the computer, physically disconnect the old HDD, then boot from the new SSD.
The activation of Windows will fly off, you will need to activate it again.
Reflect supports cloning a smaller disk to a larger, larger disk by a smaller one.
