method is recommended, mainly low costThere are several advantages:1, compared with the physical image of such technology, this scheme is more economical. Backup service hardware requirements are not high, as long as the hard disk is large enough.2. Although SQL Server provides several backup verification mechanisms, the only way to ensure full reliability of backup is to actually recover it.3, early recovery backup, so that when a real disaster occurs, only need to restore the last log backup.

included with SQL ServerDatabase Not supported The resource database is located in the Mssqlsystemresource.mdf file,The file contains nearly the code. Therefore, SQL Server cannot back up the resource database.However, it can be done through file backup and backup to disk, and not through SQL Server when restoring.To restore these backups, you can only manually restore the backup copy of Mssqlsystemresource.mdf.And be careful not to overwrite the current resource database with a

database, MYSQL-BIN.000023 also records the updated content, recovery of mysql-bin.000023 updates after full and incremental recoveries, backup mysql-bin.000023 refresh Binlog, incremental recovery of mysql-bin.000023 and incremental recovery of updated Binlog, so that the deadlock is old to recover.The second problem is that when we recover incrementally, mysql-bin.000023 also records the updates for full and incremental recoveries. After the full and incremental recovery to restore the record

You can usually shorten the duration of an activity by using some of the following methods(1) Invest more resources to speed up the process of activities(2) Assigning more experienced people to complete or assist in the comp

considered much about security, as stated in the redis Getting Started Guide. "Redis's security design is in" Redis running in a trusted environment ". during production, external connections to the Redis server are not allowed, but applications should be used for transit" In this way, penetration personnel may be able to see the wealth of redis and make good use of it. Ii. Start/close operationsNow you can run it. Start the serverRedis-server redis.

Again, the purpose of this series of articles is to strengthen operational management capabilities, i.e. not deployment or general configuration, which requires some basic theoretical knowledge. If you have friends who need to understand the deployment of exchange or basic operations, you can refer to other resources, or see my previous Exchange series articles.This article will learn about the storage prin
