Thanks a lot. So I should create a snapshot first then I can move it with btrfs send
?
Specifically what I would like to do as a test would be to move one directory to my HDD with this technique aforementioned.
So the data I am copying is at this path
/home/solomon/Documents/Tax
And I want to move it to the sdb drive.
[solomon@fedora Tax abatement strategies]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 232.9G 0 disk
└─sda1 8:1 0 232.9G 0 part
sdb 8:16 0 2.7T 0 disk
└─sdb1 8:17 0 2.7T 0 part /run/media/solomon/3TB WD Red
sdc 8:32 0 223.6G 0 disk
├─sdc1 8:33 0 600M 0 part /boot/efi
├─sdc2 8:34 0 1G 0 part /boot
└─sdc3 8:35 0 222G 0 part
└─luks-2aafcb54-d261-46b8-8423-2ccc7ddc45cb
253:0 0 222G 0 crypt /home
/
sdd 8:48 1 0B 0 disk
sde 8:64 1 0B 0 disk
sr0 11:0 1 1024M 0 rom
zram0 252:0 0 8G 0 disk [SWAP]
[solomon@fedora Tax abatement strategies]$
so according to the path on the partition it would be
/run/media/solomon/3TB WD Red
So would I enter
sudo btrfs send "path of the location where the snap shot is" | sudo btrfs receive /run/media/solomon/3TB WD Red
I dont seem to have a snapshot directory anywhere in the system though.
I also must ensure the receiving disc drive has a btrfs filesystem which is does
