[130 _ Storage Service] 005 _ Fujitsu storage system eternus _ online high-speed backup/recovery for the global environment

Original article:

Eternus disk storage systems provide advanced copy functions that enable server-less volume copying within the disk storage system unit. used in cooperation with backup software that supports continuous system operation, these advanced copy functions significantly minimize the time taken for backup or recovery.

The equivalent copy function, advanced copy (EC), is used by the disk storage system to create a backup volume equivalent to the online source volume. This is done in parallel to online operations.

By this method, data backup, which traditionally takes several hours, can be stored med within the disk storage system in several minutes. then replicated data can be backed up to a tape library at anytime. such combinations of eternus disk storage systems and a tape library enables high-capacity long-term data storage in 24x7 environments.

In the case where an online volume is already upted, data can be quickly recovered from the backup volumes using the one point copy function, advanced copy (OPC ). this means the online service can restart immediately.

Translation:

The advanced copy feature provided by the eternus disk storage system makes it possible to copy data within the disk storage system, and weakens the role of the server. If advanced copy and backup software supporting uninterrupted services are used in parallel, advanced copy can obviously shorten the data backup or data recovery time.

The peer copy, that is, the advanced copy (EC), is usually used to create a backup data equivalent to the online business data. This is parallel to online operations.

In this way, it would have taken several hours to back up data, but now it takes only a few minutes to back up data within the disk. You can back up data to the tape storage system at any time. The relationship between the eternus disk storage system and the tape storage system can maintain uninterrupted services.

When the online data is corrupted, you can use the OPC method of advanced copy to quickly restore the data. This means that the service can be quickly restarted due to instant downtime and other problems.

It is about the advanced copy in the global environment:
