The 11g active data guard implements rman backup for the standby database, so that the database can be backed up without affecting the external services of the primary database.
The test is as follows:
SQL> select OPEN_MODE, PROTECTION_MODE, PROTECTION_LEVEL, DATABASE_ROLE from v $ database;
OPEN_MODE PROTECTION_MODE PROTECTION_LEVEL DATABASE_ROLE----------------------------------------------------------------------------READ ONLY WITH APPLY MAXIMUM A

We can perform full backup for a small number of databases every day, because it does not take much time. However, when the database is very large, we are unlikely to perform a full backup every day, in addition, it is changed to a weekly full backup, and an incremental backup every day is similar to this

LVM (LogicalVolumeManagement logical volume Management) achieves almost hot backup principle: the snapshot volume of LVM can be used to save the instantaneous state of the database at a certain time point. You only need to back up the snapshot at that time. LVM snapshot principle: After lvm creates a snapshot volume for a volume, the snapshot volume serves as another access point for the original volume.
LVM (Logical Volume Management) achieves almost
This article describes how to use shell to implement full and incremental mysql backup. Incremental backup copies the mysql-bin.00000 * to the specified directory at Monday-Sat, while full backup uses mysqldump to export all the databases at every Sunday, and will delete the last week left by the mysq-bin.00000 *. Then, the mysql
I wrote two blog posts on VPS security settings in a few days. In fact, no matter how secure we are, backing up VPS data in a timely manner is the most important thing. Because the VPS is different from the host, the host may often be backed up by the service provider on our behalf. Most of the operations and security of VPS require us to be responsible for this. Even if many VPS provide daily backup services, but there are too many uncertain factors.
