What is the best way to copy files from one computer to another using ZFS or checksumming?
I have a FreeNAS server with ZFS and a Mac with Mojave and ZFS.
I want to copy a large (4 TB) Time Machine sparsebundle from the server to the ZVOL on the Mac over the network.
I wonder if there is a ZFS-enhanced way to do this, which perhaps includes metadata or checksums.
Apparently ZFS only includes options for copying (send/receive) complete filesystems or volumes, not individual files.
I found the command
cp -z
on an Oracle online manual, but this apparently does not work in the macOS terminal.
Any idea?
There is no way to leverage ZFS for this using any of it's features other than send/receive. Unless you are transferring an whole fs or volume snapshot (full or incremental), ZFS can't help you.

Is it possible?
I've tried adding the external drive (i.e., drive to be backed up) in Windows backup options, but I just get an error (0x80070032).
If it matters, I'm using an HDD for backup, and an SSD that needs to be backed up.
I came across "AOMEI Backupper". It does the job, and actually did save me from losing 6 months of work (from home). However, I ended up just buying a bigger SSD and backing up to an external SSD (so I have a portable copy if needed).
AOMEI works, but is a little "rough around the edges", if you know what I mean..

How do I access an external hard drive through bash-on-Ubuntu-on-windows. It doesn't seem to appear in either /media, /mnt or /dev, which seem the common places that people say to look for them in Ubuntu systems.
Note: the hard drive is HFS+ formatted: I use Paragon's HFS+ for windows and have already done an apt-get install hfsprogs which I think should allow the Linux part to read the HFS+ format. I have also tried with normal USB sticks, no of which seemed to appear anywhere.
The drive does appear in /cygdrive in cygwin, but when I navigate to cygdrive in bash it doesn't appear. Clearly it is not properly mounted there, but is some form of symbolical link that bash cannot see.
I'm not really sure if this is a Linux or a Windows issue, but there doesn't seem to be anything from Microsoft about it, though I realise it is early days for them.
The Ubuntu on Windows on the current build (Build 14393, a.k.a. anniversary update) doesn't support accessing external drive. This feature is on their backlog for future consideration.

Edit: Mounting removable drives are supported since Build 16176. [1][2]

I am very new to programming in anything. I want to get started with Ruby. I have a pc and laptop. I don't want to limit myself to just the pc. As long as Ruby is installed on both, of course, can I keep my project files in DropBox so I can work on them from either device?
Thanks for your help.
Don
Yes. Source code files can be kept in Dropbox just like any other file. You can use Dropbox to keep your files in sync between your two computers.
As you find yourself more comfortable with programming and make programs of greater complexity, you will probably want to use a version control system (VCS), such as Git. Among many other things, a VCS will keep your project files centralized in a repository. If the repository is in the cloud (e.g. on GitHub) you will be able to access it from all your computers.

I'm using a Mac to remotely access a computer in my university's computer lab. The Mac serves as a terminal. If I need to transfer some files from my computer into the one in the lab, is it, firstly, possible? If yes, then please guide me to it.
Absolutely, use the UNIX / Linux command scp (secure copy):
$ scp user#server:directory/SourceFile TargetFile
Update based on OP's response:
$ scp path/to/my/file.txt user#server.com:/path/to/copy/to/file.txt

I can access most of the folders on my mac partition but some I can't.. there is no pattern..
it says "xxxx is not accessible. Element not found."
Also I noticed that in some folders there is an old "snapshot".. the files have already moved but it is not reflected from the windows side... the strange thing is that I can still open some of the files that are actually no longer there (they moved to a subfolder for example).
What is going on? Can I make all my Mac files reliably accessible all the time?
thank you!
david
The solution: I installed MacDrive program in my Win7.. now the Mac partition is reliably readable and I can write to it also..
