The second type of backup mode is logical backup, which is used by the business database. This method does not require the database to run in the back-to-back mode, which is not only simple, in addition, external storage devices are n

the backend of an uncompressed file ''. tar '', the compressed file with the ''tar.gz ''' -- directory ''option tells tar to jump to the following file path (in this example, the '/' directory) before starting the backup ). The '-- exclude' option instructs tar not to back up the specified file or directory. The '.' symbol tells tar to back up everything in the current directory. Note: It is important to know that the tar options are case-insensitive! In addition, most of the options can be sim

Rman usage in Oracle 10g is primarily concerned with the best way to restore disk backup as a media recovery solution. As disk prices have fallen, a large number of storage area networks (Storagearea Network:san) have found permanent storage space in many data centers. As the business progresses towards a more affordable and affordable disk, the functions of rman, such as flashback, are upgraded to make the most efficient use of available storage space. The RMAN Backup utility is a logical proc

During the recent period, two of the many priorities that storage managers face seem to be mutually exclusive: disk to disk (D2D) backups seem to contradict the energy savings. Storage experts deploy disk to disk Backup in 2008, or expand their investment in this area to improve data protection performance and secure data recovery. Compared to traditional tape-based data protection, disk to disk has proven to shorten backup windows, improve recovery

RMAN performance optimization full strategy (I) It is easy to say that RMAN is doing operations during backup and recovery: Reading data from the "Source" to the buffer zone, then the self-read buffer is written to the "destination", and a lot of operations will occur in this process to complete the data block verification. If an operation is slow, we call it the key to bottleneck detection is to pick out the bottleneck ① determine the maximum speed of the backup source and backup device from th
