Therefore, the recovery model is typically changed to the bulk-logged recovery model only when a large number of data operations are required, and the recovery model is changed back to the full recovery model immediately after the data has been processed.

restored from the specified file. -X FileName does not process files listed in the given file. --exclude=pattern The specified file is not processed. backing up files with tarTypically, the backup file is stored in a separate partition, either a partition on the system's local hard disk, or a partition in another mounted mobile device. Therefore, before backing up, you should create a mount directory and mount the file system.# mkdir/

is the basis for an incremental backup of the InnoDB table, that is, Innobackupex is implemented by backing up pages that have changed since the last full backup.To implement the first incremental backup, you can use the following command:# Innobackupex--incremental/backup--incremental-basedir=basedirWhere Basedir refers to the directory where the full backup is located, the Innobackupex command creates a new time-named directory in the/backup directory to hold all the incremental backup data a

Why a backup is requiredIn a real-world production environment, it is a mistake to delete the operation, the hardware damage will result in the data is not available, this time we need to backup to achieve disaster recovery. Hardware-level redundancy is also required, such as RAID, and it is not a substitute for backup operations, since data is not deleted after it has been mistakenly erased, so back

recovery model. To put it simply, it is necessary to minimize logging of bulk operations and save space for log files (such as importing data, batch updating, SELECT into, and so on). For example, when you insert hundreds of thousands of records in a database, in the full recovery model, the action of each inserted record is recorded in the log, making the log file very large, and in the bulk-logged recovery model, recording only the necessary actions and not logging all, which can greatly impr

supported. What is recovery mode? Many people only focus on the backup, not the recovery model, in fact, all the backup should be from the recovery model as a point of entry. The recovery model is actually a database-level option that controls the behavior of the backup restore. SQL Server has only three recovery models in all current releases: The Simple Recovery Model (hereafter referred to as simple mode), the bulk-logged recovery model (hereafter referred to as the large capac

One: There are several ways of database backup, there are several ways to restore the database 1: Restore of full backups 2: Restore of differential backups (you need to restore the most recent full backup, then restore the most recent differential backup, and if you have a transaction log backup after a differential backup, you should also restore the transaction log backup) 3: Restore of the transaction l
