Oracle databases have two types of backup methods. The first class is a physical backup, this method realizes the complete recovery of the database, but the database must run in the return mode (the business database runs in the non-return mode), and it needs a great external storage device, such as a tape library; the second type of backup is a logical backup, and the business database uses this method, This method does not require the database to ru

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

Data backup and Recovery topology Data backup and Recovery description Basic data backup and recovery with Mirage Virtual Tape library includes a backup server, a backup software, a set of mirage Virtual tape libraries (one Mirage device, one disk array). The backup servers, backup software, disk arrays as virtual tape Library storage media are available on t

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

, that's very large. In addition, primary storage is designed to quickly transfer over process data. It basically does not support data recovery regulations or years after it has been written to storage, and cannot verify the integrity of this series of data. These are important requirements for archived storage. 　　Archive Target The first step in archiving is to select a storage platform for the repository. This element must be the first step, because the selected platform determines how the po

Article Title: backup and recovery on Linux servers. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source and other basic categories for general backup should be the highest priority for responsible system managers. Although Linux is a highly reliable operating system, system failure may still occur. It may be caused by hardware failure, power interruption, or other unexpected problems. More

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

A common question for Linux system administrators is: how do I back up my system? For Windows systems, it is easy to back up data (you only need to click the mouse in menu mode ). Linux backup is much more troublesome. If you are not familiar with Linux system files and devices, the situation will become worse.

We will begin by discussing the source of backup and recovery issues, exploring generic types of solutions, introducing selection criteria, and providing information about specific netapp® backup products, including NetApp Virtual tape library (VTL) solutions and NetApp snapvault®.

HP always believes that backup is only a means. The purpose of backup is to prevent data disasters, shorten the downtime, ensure data security, and upgrade server hardware. The ultimate goal of backup is recovery! The tape drive provides cost-effective backup ~ 20% of investment, achieving 100% reliability. Many system administrators and CIOs have some misunderstandings about backup. One of the misunderstandings is that copy is used instead of backup

, this is the core challenge of NAS backup, and the network performance of the NAS is uneven. 　　Q: Is ndmp a good choice for NAS backup? How does it work? 　　Answer: NDMP was introduced to the industry about 10 years ago. That's when NetApp started to become active, and NetApp NAS devices are the kind of equipment that you can back up with headaches. Then people would ask, "How exactly do you back it up?" ", the first answer is:" It is NFS, so just use the NFS backup on the line. ”。 However, m
