It’s not often that we hear the stories of a data center being destroyed, but it happens. If your backups remain onsite, or even worse — they stay in the tape library for a week before you remove them, then you are at risk if a disaster strikes. We actually had a customer who had a fire in their building. The tape was still in the tape drive. Pete’s advice was to cut the cable and grab the tape drive and run. This is not a good disaster recovery plan.
When I was a System Administrator in the early 1990s, my colleague and I took our backup tapes home to keep them offsite. I didn’t have a fireproof safe, I just had a box with tapes that I kept safe. On Friday night, the backup would run sometime after the JDE nightly process would finish and the tape would stay in the tape drive until Monday morning at 6 AM when one of us arrived. That tape stayed in the building all day until after work when it would leave with whoever had the early shift that week. We had a backup, we even took it offsite, but was it really the best solution? No. It was what we knew at the time.
It’s plain and simple. You must execute backups daily. No excuses! It’s not just about being able to recover in a disaster; you also need to be able to recover a file that is accidentally overwritten or deleted.
If you have high availability and you think you don’t need to back up every day, you really should reconsider your strategy. Replication ensures that your target and source data are in sync, but if you delete a record or several records you need, you can’t get them back with replication. Backups protect your business data, which is a valuable asset.
It’s that time of year again, hurricanes, tornadoes and severe thunderstorms are back again. Which means you’re at risk, especially if you haven’t done a recovery test of your backups recently. What are you waiting for, a natural disaster?
While it may be common sense that you need to keep a copy of your backups offsite for recoverability, we encounter many companies who are not religious about removing tapes from the drive. It’s imperative that you store your backups offsite in case of a disaster. It doesn’t matter if you use physical tapes or virtual tapes, you need to make sure there is a copy in a second location.(more…)
On April 23rd, 2019, IBM announced the newest release of the operating system IBM i 7.4. The announcement contained hundreds of updates to the OS and licensed programs.
One new licensed program, DB2 Mirror for i was also announced. It provides continuous availability for IBM i applications. “Continuous Availability” is a new term, which previously we had High Availability.

Now that I have your attention, I want to discuss a serious topic; disaster recovery. In the event of an actual disaster, you want to be able to recover as quickly as possible to reduce the number of transactions that you lose, and the business you will lose as a result.
The real question is: Have you ever tested your disaster recovery process?
If the answer is, “no” or “not in a few years”, then your DR system might be nothing more than a boat anchor.(more…)
