It is normal for the production environment to mistakenly operate in MySQL, so it is necessary to use the incremental backup of MySQL for recovery.Incremental backup is a common use, it can specify a wrong operation time and location point for data recovery, more accurate recovery of the data we want to restore.The following experiment shows you how to recover data by using incremental backups for the wrong

This article does not introduce the simple import and export operations on database data using mysqldump. Here we will introduce how to perform Incremental Backup Data and restore Data Based on mysql binlog logs. Mysql Incremental Backup A small number of databases can be fully backed up every day, because it does not take much time. However, when the database is very large, it is unlikely that a full backu

Original file Address: http://blog.itpub.net/29806344/viewspace-1400942/When the database data is very large, and there is new data inserted in real time, if we do not update the index, the new data will not be search, all re-index and consumption of resources, in this case we need to use " primary index + incremental Index " to realize the real-time update function. Because at this point we have the primary index and the

ProblemRsync is very useful for synchronizing data, especially for incremental synchronization. But there is a situation where it is not very useful to add a specific parameter. For example, you want to sync multiple files of dozens of G, then the network suddenly disconnects, you restart the incremental synchronization. But the discovery waited for a long time not to carry out data transmission, but the ma

When backing up Mysql Data, you may encounter a large data base. If you back up the entire database every day, it will consume a lot of resources, at this time, you can use BINLOG for Incremental backup and record a breakpoint every day. During the backup, you can perform Incremental backup from the previous day's breakpoint. In another case, you can also use Incrementa
