Online high-speed backup/recovery for GlobalServer environments
ETERNUS DX provide Advanced Copy functions that enable server-less volume copying within the ETERNUS DX. 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 ETERNUS DX 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 performed within the ETERNUS DX in several minutes. Then replicated data can be backed up to a tape library at anytime. Such combinations of ETERNUS DX and a tape library enables high-capacity long-term data storage in 24 x 7 environments.
In the case where an online volume is corrupted, 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.
