FDRINSTANT AND IBM/STK SNAPSHOT

FDR InstantBackup, an additional cost FDR facility for non-disruptive backup, is a key must have ingredient for the e-business initiative and critical business continuance plans of every Hitachi Lighting 9900 customer.

HS ShadowImage is an optional feature on Hitachi Lighting 9900, 7700/E and 7700 Freedom Storage, which allows for the "instant" creation of exact duplicates of existing DASD volumes.

FDR InstantBackup works in concert with ShadowImage to provide instant disk backup, non-disruptive full volume, data set and incremental tape backup as well as ABRInstant restore from ShadowImage disk.

FDR InstantBackup together with ShadowImage, enhances the FDR Storage Management functions of:

• FDR full volume backup - FDRDSF data set backup - FDRCOPY data set copy

• ABR full volume backup - ABR data set and incremental backup

And introduces new capabilities for:

• ABRInstant full volume and data set restore

Using technology developed by Innovation Data Processing, FDR InstantBackup provides non-disruptive backup of, both SMS and non-SMS, offline MVS DASD volumes Conventional disk backup is disruptive of normal operations. It must obviously take time to backup a data set or disk volume. If data sets are being updated by an application during the back up, the backup copy may not be valid and the data sets may not be usable when restored. The usual response to this problem is to quiesce all updates to data during the time a backup is running. This disrupts normal business operations until the backup is complete.

Using FDR and ABR together with FDR InstantBackup and HDS 's ShadowImage feature, you can instantly freeze a copy of an online disk volume at a specific point in timeand then easily backup or copy data from that frozen point in time copy as if it were the original volume.
