Backup method: Logical backup and physical backup Logical backup: The data is backed up by dragging the logical export. The logical backup data can only be dumped at the backup time. Therefore, the recovered data can only be recovered to the data saved during the backup. logical backup is suitable for backing up data tables with few changes. If you use logical backup for full database recovery, you usually need to recreate the database and import the

Informix is a relational database management system that can be used to develop powerful applications that can run on multiple platforms. Informix Database Dynamic Server (IDS) is the core of INFORMIX database technology products, featuring scalability, scalability, manageability, and efficient operation. Because Informix is mostly used to manage large applications, data backup and recovery is an important task for database administrators. Therefore,

Timeout retransmission is an important mechanism for TCP to ensure data reliability. Its principle is to enable a timer after a data is sent,If no ACK packet is sent within a certain period of time, the data will be re-sent until the message is sent successfully. This is dataA repair mechanism is provided when the package is lost. Generally, retransmission occurs after timeout, but if the sender receives more than threeThe duplicate ack should realize that the data is lost and needs to be re-tra

The target database version is oracle8.1.7, the directory database version is oracle9.2.0, and all data files (including control files and On-line log files) are lost. Examples of using RMAN for backup and recovery are as follows: Tutorial steps: 1.

This article describes how to improve the efficiency of DB2 data backup and recovery. When designing a data backup and recovery solution, we mainly consider two aspects. The first is whether the backup and recovery policies are secure, that is, whether the database can be backed up in a timely and accurate manner. Second, the efficiency of data backup and

In RAID array data recovery, we often encounter simple structure such as RAID1, RAID0, RAID5 and so on array data recovery, such array data recovery is generally difficult, the data recovery success rate is higher. However, when encountering complex structure of array type, such as composite array structure raid0+1, ra

The two problems are: whether the backup and recovery policies are secure, that is, whether the database can be backed up in a timely and accurate manner. The second is to consider the high efficiency of the DB2 data backup and recovery solution.
