Hi @dpell352,
So you are already using a recent version of Grafana and as the issue was solved by the user so seems like an issue with the Database stability.
SQLite is good for local test env. or in small production env. where there is not much going on. However, the recommendation is to use e.g. MySQL or Postgres etc as the backend Database which provides more stability and better performance in the longer run.
For the back question, we do have documentation which describes how to take backup.
Also, check this post where community users shared some more valuable tips for the backup n restore.
For the last part of backing up Dashboards, you can check here as it list some 3rd party scripts which are related to Dashboard import n export.
Let us know if this helps.
