How to copy backups to multiple drives? (the "3" in 3-2-1)

I'm setting up a backup process from scratch.
Currently planning to use Macrium Reflect (MR).

I want to store backup images on multiple drives (3 of them).
How to copy images produced by MR to other drives?

First, I wanted to use FreeFileSync or TeraCopy, but seems that Macrium Image Guard (MIG) doesn't allow that.
From the first look at its settings, I understand that it only allows images to be copied by robocopy.

And now the questions:
  1. Is the robocopy really the only option to copy MR images?
  2. robocopy can't verify that the copied files are the same as the source. Is it necessary at all? If yes, how to do that efficiently?
  3. If I switch to a new external drive, it is empty, but I don't want to fill it with all previous backups, I want to only copy newer images. Should I fiddle with PowerShell scripts to make robocopy copy images only starting from a certain file creation/modification date?

To my knowledge, Macrium's MIG feature DOES NOT keep you from copying files, it only protects those files from unauthorized "modification" (Write/Delete). You should be able to use any file sync/replicate app to move that DATA elsewhere.

1. No, anything can copy a file, it's only write/modify/delete access that's blocked. This includes the file attributes, so if an app like FreeFileSync or TeraCopy tries, for example, to clear the Archive attribute after copying, that will be blocked.

2. No, RoboCopy only compares source and destination file size and date. I have never had any issues copying image files. If it is of concern you could use Reflect to verify the copied image later.

3. You could use Xcopy rather than RoboCopy. That has a 'date' option.

Code:
XCOPY source [destination] [/A | /M] [/D[:date]] [/P] [/S [/E]] [/V] [/W]
                           [/C] [/I] [/-I] [/Q] [/F] [/L] [/G] [/H] [/R] [/T]
                           [/U] [/K] [/N] [/O] [/X] [/Y] [/-Y] [/Z] [/B] [/J]
                           [/EXCLUDE:file1[+file2][+file3]...] [/COMPRESS]
                           [/[-]SPARSE] [/NOCLONE]

  source       Specifies the file(s) to copy.
  destination  Specifies the location and/or name of new files.
  /A           Copies only files with the archive attribute set,
               doesn't change the attribute.
  /M           Copies only files with the archive attribute set,
               turns off the archive attribute.
  /D:m-d-y     Copies files changed on or after the specified date.

I am a user of Macrium Reflect (Paid version).

I, too, generally follow the concept of copying backups to more than one drive.
Here is the method that I use:
1.) Choose which drives will be your backup targets
2.) Create one (or more) backup scripts within MR targeting those drives. In my case, I have MR execute different scripts on different days of the week.
3.) Each script does allow for one to select alternate targets in the event that the primary target is offline or unavailable at the time backup script begins.

Also, in regard to Image Guardian, one can use MR interface to remove this guard, temporarily, on a drive for things such as file deletion and modification.

Hope this helps.

True, and if (as I often do) you forget about this, then when MIG blocks you the popup gives you the option to go to MIG settings and change it on the fly.

First, I wanted to use FreeFileSync

If Macrium is running, FreeFileSync may be having a problem with accessing the file/s.
FreeFileSync can have issue with some files if a program is open (locked files)

    …still on a horse.
My 3-2-1 approach is different and doesn't involve copying images. My approach is that the offsite image will be used to at least protect most of my data if absolute disaster happens. Oldest image will always be there with newest images on 2 different ssds in my office. Each of the 3 backup disks has at least 2 images on it. I rotate one of the disks from my office to offsite every 3-4 months.

Even if I wanted to have a current image on all 3 disks, I wouldn't copy when it's much faster to create a new image. Personally, I keep little in the cloud, but IMO if one's personal data is so important they feel they can not live without ALL of it if disaster strikes, then that data should be syncing to some cloud provider.

robocopy can't verify that the copied files are the same as the source. Is it necessary at all? If yes, how to do that efficiently?
  1. Forget Robocopy
  2. Use FastCopy with the Verify option.

No, you most definitely should not.

Oh, thank you all so much for the responses. I didn't expect this forum to be this friendly and helpful (after visiting r/DataHoarder).

Thank you! Will try to figure out how it works. Honestly, didn't expect it to be that complicated.

@Froggie @Bree
I just re-ran the same copy and it completed without any problem (with the Guardian on).
Probably what I've experienced before was a combination of conditions. I'm still clumsy with this software. What could be the reason is that the destination was included as an alternative target in one of the Macrium Reflect backup definitions.

I wouldn't copy when it's much faster to create a new image.
I read a lot of forums and threads and it occurred to me that there are two camps: the ones who backup then copy, and the others who repeat the same backup for multiple drives. So I just got frustrated and made just a coin flip decision to backup then copy. Still not sure which is better.

  1. Forget Robocopy
  2. Use FastCopy with the Verify option.
Okay, that's another stumbling rock. I remember seeing robocopy being mentioned on Macrium's blog. Some swear by it, some say that software X should be used (FastCopy, TeraCopy, whatever-copy, ...).

I think I'll start with this approach, because it appears the most straightforward to me at the moment:
  1. Schedule automatic backups (from different locations) 'cause it'll be hell to do them all manually. Backups should go to an internal HDD (intermediate location), so I don't have to keep external drive(-s) attached to the PC.
  2. Still copy images manually from the intermediate location to all the external drives. When I finally get bored with it, I'll try to automate the process. No clue how.

Welcome to Eleven Forum. We pride ourselves on being a friendly bunch here....

Probably what I've experienced before was a combination of conditions.
IMG does not block copying an image file to a drive on which Guardian is enabled. I've just tested that in File Explorer (deleting the test copy was another matter, when it was blocked I had to turn off IMG for 1 minute, then click the 'retry' button).

I remember seeing robocopy being mentioned on Macrium's blog. Some swear by it, some say that software X should be used (FastCopy, TeraCopy, whatever-copy, ...).
The reason Macrium mention RoboCopy is simply because it's the only other thing, besides Reflect itself, that can be given permission to work while IMG is enabled.

My 3-2-1 approach is different and doesn't involve copying images. My approach is that the offsite image will be used to at least protect most of my data if absolute disaster happens. Oldest image will always be there with newest images on 2 different ssds in my office. Each of the 3 backup disks has at least 2 images on it. I rotate one of the disks from my office to offsite every 3-4 months.

Even if I wanted to have a current image on all 3 disks, I wouldn't copy when it's much faster to create a new image. Personally, I keep little in the cloud, but IMO if one's personal data is so important they feel they can not live without ALL of it if disaster strikes, then that data should be syncing to some cloud provider.
I agree with you @glasskuter. It's much faster to create a new Macrium Reflect image than to copy a backup. A complete image of my 1TB C drive takes only a little over 3 minutes to make!

I make daily Macrium Reflect images on two separate Samsung 4TB T9 Portable SSD drives. Each T9 SSD contains 7 rotating images.

I keep all my data and photos in my local OneDrive folder. I set my local OneDrive folder to mirror to cloud OneDrive in real-time so I will never lose anything as I work adding and modifying data and photos throughout the day.

Thus the 3-2-1 rule.

3 copies of my data
2 different backup technologies
1 copy must always be offsite

Why not simply run Macrium concurrently 3 times with output target to different devices. Macrium I'm sure can run multiple instances at the same time especially if data is being imaged rather than "cloned".

The reason Macrium mention RoboCopy is simply because it's the only other thing, besides Reflect itself, that can be given permission to work while IMG is enabled.
Allright, fair enough.

It's much faster to create a new Macrium Reflect image than to copy a backup.
I didn't measure my speeds yet. If it's as fast or faster than a copy, then why not? It's just another thing people argue about: creating multiple images to different destinations vs. creating one image and copying it to different destinations.

I've been even told that the first approach is more error-prone (although I can't come up with any reasons why) and I definitely should not do that.

For the reason I mentioned above. Of course, I'm not sure if it is legit reason. I'm still confused by the fact people do something straightforward like this two different ways without actually having explanations. (I don't mean you but rather other forums where people just don't listen to each other and suggest two opposite opinions, leaving the OP with what he started with or even bigger frustration).
The only reason I'm personally afraid of starting 3 parallel backups could be:
  1. to not test if Macrium Reflect corrupts images in this case;
  2. to not have all backup drives connected to the PC at the same time.

It's funny that Macrium doesn't have a guide on this. At least, I didn't find any.

Hi there
If you don't have different devices concurrently connected to the computer then you obviously can't run parallel backups. Running sequentially will take longer of course and unless you run these from a different host OS then something couyld change between the backups.

I'd do the parallel run myself. But each to their own.

There may be issues using the same application, at the same time, invoking FileSystem snapshots via VSS. Never tested by me but have seen issues by other users. Maybe someone can fill in here...

Okay, that's another stumbling rock. I remember seeing robocopy being mentioned on Macrium's blog. Some swear by it, some say that software X should be used (FastCopy, TeraCopy, whatever-copy, ...).
For reasons that are not wholly dissimilar to why I avoid whatever-copy like the plague, I avoid Macrium like the plague.
I think I'll start with this approach, because it appears the most straightforward to me at the moment:
  1. Schedule automatic backups (from different locations) 'cause it'll be hell to do them all manually. Backups should go to an internal HDD (intermediate location), so I don't have to keep external drive(-s) attached to the PC.
  2. Still copy images manually from the intermediate location to all the external drives. When I finally get bored with it, I'll try to automate the process. No clue how.
I don't schedule automatic backups, as I only have 2 laptops, and I don't need to create images besides ones that let me avoid the potential risk of losing too much valuable time, i.e., in the possible event that the laptop's internal SSD breaks or the Windows installation on it gets so severely damaged that I would be forced to perform a clean install of Windows otherwise (losing all apps, settings and configurations, Windows updates and driver updates).

I know I could always decide to set up iPXE chainloading to run my own custom script that would let me achieve automated image creation with Ventoy through an iSCSI device, for example, but IMO this would be a tad overkill when all I basically need is just a (customized) incremental system backup maybe once or twice per year and a new (also customized) base image maybe every couple of years.

I use FastCopy (with the Verify option plus the option to calculate and wrtite file hash codes to the log file) to copy images manually from the laptop's internal SSD to multiple external USB 3.0 HDDs, but I only make customized system images of the Windows partition plus the other partitions that are required to keep Windows fully functional. "Customized" here means that things like cache files, temporary files, and all personal files are excluded from image.

I also use FastCopy to, also manually, copy important personal files from the laptop's internal SSD to multiple external USB 3.0 HDDs (and occasionally the other way round). The Verify option used in conjunction with on-the-fly calculation of file hash codes written to the log offers a reliable way to ensure that the method used to check the integrity of the copied data is robust. Additionally, FastCopy has per-file error logging with full Unicode support also in the log files.

I use a little bit of a different approach. First, I use a product called "StableBit DrivePool". Think of this in very rough terms as something like Windows Storage Spaces, but far superior. I have StableBit set to make triplicate copies of any data in the folder where I store my Reflect backups. As a result, when my daily backups happen, they are automatically stored 3 times.

@hdmi, after reading that, I honestly don't know what to say. We live in different worlds.
To clarify, the main point I was trying to make is that my own personal backup needs are pretty much identical to the average home user's (although most users don't know very many specific/technical details about what their own personal backup needs are, which is unfortunate).

It also means that making system backups (i.e., backups that contain the operating system, applications, and all the various settings/configurations that have been applied to it/them) frequently enough to warrant an automatic, or scheduled backup scheme specifically for this purpose is not on my list of requirements. In essence, it means that any reliable method to manually create an image of one or more partitions (i.e., the Windows partition plus the other partitions required to keep Windows fully functional such as the EFI System Partition, or ESP and the Recovery partition that contains the Windows Recovery Environment, or WinRE) could be already sufficient to suit my needs in that department.

Booting to WinRE to run the DISM command from there is only one example of how this can be possible to achieve. Capture and apply Windows Full Flash Update (FFU) images
However, I don't tend to do a lot of that, as the bootable Rescue Media of Acronis True Image on a Ventoy-formatted USB flash drive offers several advantages over it (that I find important).

If I ever need to restore from image (which I never do, but I can't guarantee that I never will), then after the restore, at worst I will need to let Windows Update automatically download and install the Latest Cumulative Update, or LCU again, install a few other updates again like driver updates, update/install a few applications again, and go through some settings to re-apply them. None of all this can in any way justify the hoopla of setting up automated system backups in my view, and, for backing up personal files, image creation neither is necessary nor is feasible at all. That's just because my personal files are not partitions. Simple plain.

In short, I prefer proven reliability in conjunction with the kind convenience options that truly help to save more valuable time. That is, in lieu of a quick sales pitch about features that I already know I will never need or use. With the vast majority of image creation software products, the default method to create a system backup is a (VSS) snapshot-based backup that is created while Windows is still actively running on the system. What they don't explain to the average home user is that this method isn't ideal if reliability is what should take the highest priority.

I live in a world where people understand the fact that a very large part of these kinds of discussions demonstrate a persistent lack of awareness among most avergage home users. I am a trained Java Enterprise software developer who has a formal degree in IT. I have been programming computers over the past 39.5 years. I started out with the MSX BASIC 1.0 programming language at age 11, and, within 3 years later, I had already become highly proficient at programming in assembly language on the MSX platform, including its various hardware.
