There are several threads in the forum about that but I dont have them at hand. In general the slave server connects to the master database once a minute to check for updated records that are relevant for him and copies the changes to its local database and then runs the script to update its local configuration. So a slave is not affected when the master is not available as he has a local copy of its data and the master keeps a backlog of all changes for 30 days, so if a slave is down for maintrnance for a few hours or days, it will pick up all changes from master autmatically as soon as he is online again.
