Mirage Enterprise Data Backup System solution

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 the market, and if users have the equipment and software to take advantage of before, they will save the cost of a new purchase and retraining without spending more investment. Mirage is a pure hardware product, maintenance-free, plug and Play, through the standard interface (note: such as SCSI, FC, etc.) and backup server and as a virtual tape library storage media disk array connectivity, good compatibility.

The backup server is recommended as a separate server for backup, or by other servers. The server side of the backup software is installed on the backup server, and for the Mirage device with the SCSI interface, the Mirage device is connected directly to the SCSI interface of the backup server (Note: Mirage device supports the SAN storage environment), The disk array for the virtual tape library is connected to the SCSI interface of the Mirage device, and for the Mirage device with FC interface, the Mirage device and the backup server are directly connected to the fibre switch, and the disk array for the Virtual tape library is attached to the FC interface of the Mirage device. In this way, the backup server provides control of the virtual Tape library manipulator and the development and centralized management of the entire system backup strategy, you can automatically or manually back up data that needs to be backed up directly on a virtual tape library's disk array without the extra start and swap actions that are required for traditional library operations, which greatly improves backup efficiency. Shorten the backup window.

In order to meet the requirement of long time storage and important data storage, Mirage users can use the clone of backup software to archive; Mirage Enterprise users can also use the Mirage device's SCSI port to connect the tape device to the serverless stream state to archive, The archiving operation is implemented on the panel keys of the Mirage device, without any resources from the backup server, and therefore does not have any impact on the continuity of the business.

How data is recovered

When there is a problem with the system, the required data can be recovered immediately from the Mirage Virtual Tape library, as is the case with traditional library, but the virtual tape library brings a system recovery speed that is unmatched by traditional libraries; If you need to recover data from an archive tape, put the tape in an external tape drive, The data will be restored directly from the external belt machine to the system without first restoring the data to the Mirage Virtual Tape library's disk array.

Recommended Backup Strategies

Description

1, Backup capacity calculation: Backup capacity = Full backup x Backup frequency x Save cycle + incremental backup x Backup frequency x save cycle;

2, the use of Mirage Virtual Tape library, rely on the virtual tape library to use the disk as a storage medium for the high reliability, as well as backup, recovery time, compared to the traditional tape library (note: Traditional library due to worry about the reliability of tape and the Backup, Recovery window limits, Typically with weekly as a full backup cycle, do incremental backup of data every day, and also need to save a lot of redundant data, Mirage Virtual Tape Library backup and recovery scheme, in the development of backup strategy, can greatly increase the full backup cycle, reduce backup capacity requirements, improve backup equipment utilization, save capital investment.

Features of Mirage virtual Tape library backup and recovery

Virtual Tape library Backup is a kind of backup and recovery technology emerging from abroad in recent years, the market potential is more and more big. After a long period of market dominance in traditional libraries, traditional library in the backup and recovery work of some of the problems also gradually revealed, such as: manipulator, drive, tape multiple exposure mechanism of any single point of failure, will cause backup failure, Backup tape group any disk wear, tape, deformation, Damp and so on may cause the whole backup to be unable to restore, the time-consuming file lookup, the disturbance daily operation, the serious restriction IT service to the business ability. The Virtual tape library, which is based on traditional library, overcomes these common problems existing in traditional belt library, and simultaneously has some advantages of disk storage, and develops into a new generation of backup and recovery tools. From the recent market trends abroad, virtual tape libraries are becoming backup?
