Best/Satest way to move data out of Unraid Array

[JustOverride]

So, asking for a friend...

 

What is the best way (verifying data integrity) to move the data out of Unraid into another data storage system like Truenas or just back into a regular disk? Like what is the actual safe process, because technically there are a bunch of ways of achieving this.

 

My assumption is:

 

1. Buy a new hard drive as large as the array.

2. Run pre-clear to ensure it is clear and to pre-test it.

3. Turn off dockers/VM's, have nothing using the Array.

then..
?4. Add the hard drive as a UD and copy everything from the array '/unraid/user/' using Krusader.
?4. Add the hard drive in another system, and then copy everything using robocopy (with a 10G nic).

5. Wipe the USB and array drives and use a new system.

6. Move data back into new system.

If you want to verify integrity you can use rsync with the checksum option, note that it will take a long time, unless there are suspected issues a normal rsync transfer should maintain integrity.

Could you provide me with directions on how I would go about using rsync?

You can Google "rsync man page" for all the options, but basically would be:

 

rsync -avc /path/to/source/ /path/to/dest/
