The following commands are step by step instructions for TomoChain Masternode operators that can be used for two major use-cases:
Fixing nodes that are stuck; evidenced by a node that stays on a block and doesn't progress
Jumpstarting a newly setup Masternode; avoid waiting a week for synchronization
Basically, a compressed version of the last-known "good" chaindata is downloaded. This comes from TomoChain on a weekly basis. Remove the node's old data and update it with the newly downloaded data. Finally, restart the sync-process from this known-good checkpoint.
Note: Ensure there is enough disk space for both the tar file AND its uncompressed contents. Double the space or more.

Tip: extract the data in background
In case you can not wait for the extraction finish, you can run it in the background
nohup tar xvC /var/lib/docker/volumes/NAME_OF_YOUR_VOLUME/_data/data/tomo/ -f 20190813.tar &
