check the drives filesystem and only use snapper on btrfs

[ecruzolivera]

Hi, in my setup I have two drives, one btrfs for root and another ext4 for home, the current omarchy-snapshot script assumes that all drives are Btrfs.

Hi @ryanrhughes, just a friendly reminder of this.

@ecruzolivera What's the issue this solves exactly? If you don't have btrfs for a drive, it won't have a snapper config so it'd already be ignored unless I'm misunderstanding.

Hello, this script will limit snapper to only be called on btrfs partitions.

I have two drives, one for /root that has btrfs and another for /home that it is ext4. Without this script, the snapper script will report all partitions to be snapped including the ext4 ones.

sudo snapper --csvout list-configs | awk -F, 'NR>1 {print $1}'
home
root

And therefore the script will fail when trying to snap an ext4 partition.

My script will check if the partition is Btrfs before trying to snap it

 if [[ -d $path ]] && [[ "$(findmnt -n -o FSTYPE --target "$path")" == "btrfs" ]]; then
      sudo snapper -c "$name" create -c number -d "$DESC"
 fi

Please let me know if I was able to explain myself properly.
