Set of 2 or more Hard-linked Folder Trees while maintaining this specific archive structure?

[A X]

I have these 2 folders that have HARD LINKING between them. 

C:\Users\UserName\AppData\Roaming\iMazing\Backups\f22ebcffcdd1b508d3f7564431a9db98d69208ef-20190414-170122\

C:\Users\UserName\AppData\Roaming\iMazing\Backups\iMazing.Versions\Versions\f22ebcffcdd1b508d3f7564431a9db98d69208ef-20190414-170122\

Could I copy them to an external drive, while keeping their tree structure; HLinks, Created/ Modified Dates etc Intact? 

I came across this - https://superuser.com/questions/498235/100-reliable-directory-copy-on-windows-systems-ntfs 

Suggesting that FastCopy can do this. 

How to do this using FastCopy? 

I had asked about it Unix SE and got the following on how do do it using RSync. 

https://unix.stackexchange.com/questions/541231/working-syntax-for-rsync-copy-of-a-set-of-2-or-more-hard-linked-folder-trees-whi 

This is how one would do this using RSync (I also have s similar setup using ln.exe)

Reference list of Tools for Hard Link preserving Copying:
https://superuser.com/questions/997190/copy-to-another-ntfs-disk-and-preserve-hard-links/

• Rsync variations under Windows
  • (Several *Nix & Windows: Cygwin variations, CW RSync, Delta Copy/ Syncrify/ Synaman, GRsync, RsyncBackup, Rsync.exe pkg, Rclone, AcroSync, YInterSync)
• ln.exe - command line hardlinks - http://schinagl.priv.at/nt/ln/ln.html (Win)

Hard links between these 2 and need to maintain this STRUCTURE INTACT at DESTINATION. 

More details in the Unix.Stack Exchange post

When I DRAG and DROP these 2 as SOURCES, they end up WITHOUT the structure at DESTINATION FOLDER, and since they are same name, they end up OVERWRITING. 

Is there some way to maintain RELATIVE structure that EXISTS between 2 SOURCES with a COMMON BASE FOLDER? 

Or do we add BASE FOLDER as SOURCE and use some "Filtering" by INCLUDE/ EXCLUDE ways?

Yes.

[A X]

So I tried that - And it seems to work. I'm curious about a few things though

Source: 

C:\Users\UserName\AppData\Roaming\iMazing\Backups\

Dest: 

S:\_HDD_WD750\T61\HL_TEST\FC\ 

Include: 

f22ebcffcdd1b508d3f7564431a9db98d69208ef-20190414-170122\

(matches both folders and seems to maintain structure - will post detailed listing below that was executed)

Copy (Overwrite)

FLAGS ENABLED: 

ACL

AltStream

Nonstop

Verify

Estimate

---

TotalSize  = 634 MiB

TotalFiles = 6,158/2,334 (1,320)

TotalTime  = 0.8 sec

---- Listing Done ----

---

TotalRead  = 634 MiB

TotalWrite = 634 MiB

TotalFiles = 6,158/2,334 (1,320)

TotalTime  = 03:16

TransRate  = 3.25 MiB/s

FileRate   = 31.5 files/s

VerifyRead = 634 MiB

VerifyFiles= 8,492

I guess if ACL is enabled and Admin mode is used, exact same ACLs are copied? 

If DISABLED is it stripped of ACLs? i.e. More accessible or restrictive folders at DESTINATION? 

When it comes to Alt Stream? 

So what is the SIGNIFICANCE of ENABLING/ DISABLING this: I can read the manual but how/ why / details of what really matters? 

Pros/ Cons differences? 

Alt Stream

Copy Alternate Stream. (Only applicable to NTFS)

ACL	Copy Access Control List (ACL). (Only applicable to NTFS) (It is recommended to use with Administrative privilege) In addition, Extended Attribute(EA) will also be copied.
Alt Stream	Copy Alternate Stream. (Only applicable to NTFS)
Wipe & Delete (prevent deleted files reviving)	Rename filename and Overwrite random data before deleting. Alternate stream is not overwritten. If NSA method is checked in setting dialog, Overwriting Random data process runs twice, and overwriting NULL data process runs once.

/stream

Copy Alternate Stream (only NTFS) (to disable, /stream=FALSE)

Alt Streams information is extra data, like tags in pictures as an example.  Also, some anti-virus vendors will use the alt streams (just a place to store a little extra data)  as a flag to whether the file as already been scanned or not.  Usually you would want this information.  Regarding the permissions, as ADMIN user, you have permission to copy the permissions over.  Default behavior for permissions is to apply the default, inherited permissions in the inbound (target) destination.   Normally you would use this, unless there are custom permissions applied to files, like in the case of domain users and redirected folders.  As a general rule, don't worry about permissions and let them be applied by the target / destination server.

To describe the details of all behavior is not easy.

You should try and confirm.
