We didn't add var/lib/mysql to the list of backups until after the server problem. When the disaster restore didn't restore the MySQL databases we thought that was the problem until it was explained earlier how DAR2 backed up these files. We have, of course, deleted the var/lib/mysql folder from our backup lists now that we know how the backup of the MySQL databases actually works by dumping the databases to a folder that is already in the backup list. The log files don't appear to have been transferred when we moved back to the original server computer so I'm not going to worry about finding the cause of the original failure to restore the databases now.
