Indeed! I finally found some time to make progress:

```
btrfs replace start -B /dev/mmcblk0p2 /dev/sda1 /
btrfs filesystem resize max /
reboot

```

moved the file system to the new ssd. I also managed to set up a btrfs RAID 1 on my two 1TB HDD’s connected via USB. After creating two empty partitions on /dev/sdb and /dev/sdc (I used Cockpit for this) I did:

```
mkfs.btrfs -L "Nas" /dev/sdb -f 
mkfs.btrfs /dev/sdc -f
mkdir /mnt/nas
mount /dev/sdb /mnt/nas
cd /mnt/nas
btrfs subvolume create backup
cd
umount /dev/sdb
mount -o compress=zlib,subvol=backup,autodefrag,noatime /dev/sdb /mnt/nas
umount /dev/sdc
btrfs device add -f /dev/sdc /mnt/nas
btrfs filesystem balance start -dconvert=raid1 -mconvert=raid1 /mnt/nas
btrfs filesystem show /mnt/nas

```

With the help of [northerncoder.ca](https://northerncoder.ca/best-affordable-diy-nas-with-btrfs-raid1-on-ubuntu-server/).  
Then set up Samba to back up my Windows 10 Box. Then backed up my Linux box with rsync. So far everything works as expected.
