Lets say i need to move 10TB node

Facing dying hdd

my experience is forget rsync, just take it offline and clone it in less than 1-2h with some program or with some docker station (like this https://www.youtube.com/watch?v=mFwdZplM9bg) even 1-2 days offline is nothing, and will recover fast, but You have fullcontro and can check the disk and make sure everything cloned.

10TB cloning can take few hours, but still a lot faster than robocopy (1-2 weeks)
Unfortunately its safe to turn off the computer, some things You just cannot jump over.
You can try just disconnect the HDD, if hotswap is ON, but if You never tried before, You can easily cause some problems and need to turn off the computer anyway so, why complicate, just turn it off in first place.

Edit: i used this inateck docking station offline, just put 2 disks and press for 3 sec, and then 1 quick press to clone it. Paid like $20 for this, and im super happy. it just clones offline without need of any PC or software.
