What is IBM Full System Flash Copy (FSFC)?

Pete Massiello, iTech Solutions

The IBM Full System Flash Copy (FSFC) for IBM i was created to automate performing backups with minimal impact to a production LPAR. With this toolkit, a full system backup in a restricted state can be performed with the users experiencing a pause for (typically) less than 30 seconds.

This is achieved using a combination of the HMC to manage the partitions, the ability of IBM i to pause database transactions on a commit boundary, and the FlashCopy function of external storage to create a copy of the production LPAR, from which the backups are taken.

The Full System Copy Services Manager (FSFC) for IBM i is unique as it does not require an IASP, but instead Flashes the system ASP. This powerful and flexible toolkit provides additional functions to assist with the automation and management of FlashCopy via a set of commands you can use to create a “point in time” copy of a full system for the purposes of performing backups.

Imagine getting a full back up every night from an “alternate” set of virtual disks, with only 30 to 60 seconds of interruption.  It’s everything you wanted.  Of course, you need an HMC, external IBM Storage, and some additional resources to bring up that second partition.  If this is something that interests you, give us a call or send us an email, we will be happy to get you pricing on the tool kit and implementation services.
