Now synching the remote database with the server stopping the muscle, and run rsync. But base grow and with them grows and the downtime.
The question is how likely is it to get a broken table, if not to stop the muscle on the synchronization period? And if you do LOCK TABLES? And then another drive check. Of activity base on 99% SELECT.
PS. I know about the dumps and about the replication and actively use them, but in this case it's unreasonably difficult.
