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.

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.
For the answers to these questions, and more, keep reading.

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.

When people talk to us about backup and recovery, one of the most common questions is “how often should I be doing a full system save?”
Given we’re about to install PTFs or upgrade the OS, my response is always, “when was your last full system save?” What I do next
Check your last SAVSYS by reviewing the QSAVSYS data area with the following command, then review the Save Date/Time value of the object.

Deciding to move to the cloud is often a decision made by the business; the idea is to reduce overhead and costs. With so many companies offering cloud-based services, it can be difficult to determine which one is the best fit. The truth is that not all cloud providers are created equal, and it’s important to consider several things when selecting your cloud provider.
The key is that you have to protect your business. Which means you have to find a partner who can deliver the solution you need, and ensure that your data is protected and available.
Below are five areas you should consider when selecting a cloud provider.

This is a special edition of our newsletter due to Hurricane Florence, and our regular monthly newsletter will be delivered in 2 weeks. If you haven’t subscribed, join 15,000 other IBM i professionals by subscribing here.
On Thursday of this week, we are bracing for Hurricane Florence to hit the Carolinas with massive flooding and wind damage up and down the eastern seaboard of the United States. Right after that, we have Hurricanes Isaac and Helene currently forming in the Atlantic, their direction is still indecisive. It’s hurricane season.
Of course, the first concern is keeping you and your family safe. The Red Cross has excellent resources on Hurricane and Tropical Storm preparedness. You can see those here.
There may come a time when you ask if your business is fully prepared.

Here are some things to keep in mind:
The first question you have to ask yourself is “Do I have a full backup in case my machine is destroyed or damaged?”. This is probably the number one issue that I see in our industry today. Most businesses don’t have good backups that they can rely on.
If you are a regular reader of the iTech newsletter, you have probably heard me stress that you need to test your recovery and that it still holds out.
Take a moment to ask yourself:
If you have to pause a moment when going over those questions, we will go over some steps below to help. (Remember, the iTech Solutions team can help you get your machine restored, but if you don’t have a backup tape, there isn’t anything we are going to be able to do to restore your data.)
Once you have your backup, please take the backup tape off-site. If the whole area is being hit by the hurricane, then you can ship the tape to iTech Solutions (27 Mill Plain Rd. Suite 3, Danbury, CT 06811). Make sure you put your name on the tape. This is the second most important step to perform. Most likely if your machine is destroyed and the tape is inside the tape drive (Don’t laugh, I see this all the time), or the tape is on top of the computer, that most likely will also be destroyed. So, move that tape to another location!
Below are the most straightforward steps for performing a full system backup. Now, if you are using BRMS or have your own save strategy that is fine (make sure you are saving everything). I am just providing the most straightforward backup procedure so you can get a full system backup.
Step 1: Determine how many tapes you will require for your backup and initialize them. If you don’t know, initialize 3 tapes which should be ample for the backup. Load the first tape into the drive and use the Command:
INZTAP DEV(TAPxx) NEWVOL(FULL01) CHECK(*NO) DENSITY(*CTGTYPE)
Change the TAPxx to the name of your tape drive. Once the first tape is done, remove the tape from the drive (label it), and put the next tape in and run the command changing the tape name in the NEWVOL parameter to FULL02. Then repeat the same steps for the 3rd tape. Now, put the first tape back into the drive. If you know you only need one tape, then you just need to initialize one tape.
Step 2: Locate your Console (This will be in your controlling subsystem) and sign-on to this with QSECOFR userid or a profile with equivalent authority.
Step 3: We are now going to bring the machine into a restricted state, which means it will end all jobs on the system and knock all users off. From the Console, enter the command GO SAVE and press Enter. Select option 21 by typing a 21 on the command line and pressing Enter (Yes, you won’t be able to see the option unless you scroll down, but it is there). The next screen will be an informational screen telling you what this option does. Read the screen, and then press Enter and go to Step 4.
If you weren’t on the console, it will tell you about transferring your job to the controlling subsystem. If that is the case, you need to either transfer your job to the controlling subsystem with the TRFJOB command or go find the real console. You really should be on your console and know where your console is.
Step 4: We are ready to do the save, and we need to change the parameters. Please make sure under Devices you have the same name of the tape drive that you initialized the tapes in Step 1 above.
For “Prompt for commands” make that an “N.” For “Check for active files” make that an “N.” For “Message queue delivery” make that “*NOTIFY.” For “Start time” make that “*CURRENT.” For “Vary off network servers” make that “*ALL.” You will want to hit page down to see the next screen of options.
For “Unmount file systems” make that a “Y.” For “Print system information” make that an “N,” and for “Use system Reply list” make than an “N.” Depending on if you want to backup spool files, enter “*ALL” to back them up, or “*NONE” to not back them up. I highly recommend backing up spool files, and you should make this “*ALL.”
Now, hit Enter the system will wait 5 minutes to get to restricted state and then it will start the backups. If you are already in restricted state, you can change that value from 300 to *NONE. Your backup time is dependent on the number of objects on your machine, and their size. You will see informational messages at the bottom of the console telling you the status. It will alert you if you need to mount the second tape, or if you see “Waiting for message on QSYSOPR” at the bottom of the screen hit a System Request key and option 6 to read the messages and reply.
Step 5: When the backup completes take the tapes which you used and prepare them to be MOVED off-site.
Step 6: The system will come back up by automatically running your system startup program at the end of the backup. At this point, it might be wise to power the machine down if there is no need for usage and wait until after the storm has passed and the power is back to normal before powering it back up.
If you need assistance next week with a recovery, just contact Pete, and we can schedule one of our System Engineers to help you. Don’t forget, we also have machines and cloud-based partitions we can loan you if you happen to lose yours due to flooding, electrical issues, or other damage.
Best of luck, and we hope you and your family stay safe in the coming days.
