# sample code, use at your own risk
# script to install zfs, nextcloud using snap and moving the data to the new volume with compression and deduplication enabled.
# Do your own research as to pros and cons of zfs dedupe and compression. 
# Short advice is that compression works well unless you're mostly storing compressed file formats like media.

# install and configure zfs, assuming 2nd disk is where you want your data stored. 
sudo apt install zfsutils-linux
sudo zpool create nextcloud /dev/sdb 
sudo zfs create nextcloud/data 
sudo zfs set compression=lzjb nextcloud/data
