###Notice You will have a folder in ~/lisk-snapshot/ called snapshot/ where all your snapshots will be created and stored. If you want to use a snapshot from different place (official snapshot for example or other node) you will need to download the snapshot file (with prefix: lisk_db*) and copy it to the ~/lisk-snapshot/snapshot/ folder. After you copy the lisk_db*.tar file you can restore the blockchain with: bash lisk-snapshot.sh restore and will use the last file found in the snapshot/ folder.
If you use the schedule command be aware you will have a log file located in ~/lisk-snapshot/cron.log with this you will know what is happened with your schedule.
