How to make a good backup?

[codo1]

I installed, started and synced Fulcrum. Now I would like to make a backup, so if something goes wrong I need not do the full sync again. What is the best way to make the backup? For example would the following do OK?

1. shutdown Fulcrum
2. insert external storage with enough free space (du -hs $datadir)
3. mount under $destination_dir
4. cp -rp $datadir $destination_dir/
5. cp -p /path1/to/Fulcrum.conf /path2/to/Fulcrum.service $destination_dir/
6. Fulcrum -v > $destination_dir/Fulcrum.VERSIONS
7. unmount and take out external storage
8. start Fulcrum
