OrientDB health check and recovery best practices

Hello folks

I’d like to hear from folks who had to tinker with the orientdb in NXRM 3x. Particularly interested in how you-

  • Perform backup
  • How often
  • Run proactive health checks on the DB (or if NXRM does it somewhere)
  • Red flags that you see that must be addressed right away

From a Community topic, I was able to look this up as a procedure to perform database repairs:

connect plocal:/nexus-data/db/component/ admin admin 
repair database --fix-links 
rebuild index * 

Are there any other types beside the links that are needed? When?

Also, what do you do when some operation leaves database in frozen state (forzen.marker)?
