Dear experts,

I'm using a test enviroment to test freeze & thaw scripts on windows. I executed command:

..\bin\cache -s. -U%%SYS ##Class(Backup.General).ExternalFreeze()

then was saved log in cconsole:

Hello Community,

I'd like to share with you our article with @Regilo Regilio Guedes de Souza on AWS Amazon blog Automating application-consistent Amazon EBS Snapshots for InterSystems IRIS databases. Our team has created this step-by-step instruction to create application-consistent snapshots for InterSystems IRIS databases. In this article, we outline how to automate pre-scripts to pause I/O and flush buffer to disk and post-scripts to thaw I/O, as shown in the following figure:

Hi, I was wondering if anyone already dealt with this issue:
"System has been suspended for over X seconds, exceeding the maximum duration specified. Allowing system activity to resume. Any ongoing backup has presumably failed. Next InterSystems IRIS backup must be a full one"

our backup system "Commvault" is automatic, how do you tell it once you get this message that the next backup should be full?

Hi community,

We have a developed a new version of a production, all the code is new and has changed BP. This application load information for some brands and stored in database.

The customer wants to implement the changes only for some brands because he wants to check for small brands before to implement for all brands.

My proposal is create a new namespace, with the new code, and disabled all load of brands except the brand that he wants to check.

I'm wondering what is the best way to clone the namespace.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)

I am trying to get data out of a cache backup. I am completely new to Intersystems Cache.

I got a docker image of Cache from this post:

I want to get the data from my backup into this docker image. First, I need access to a gui and a cli, then I need some instructions or documentation for actually pulling in the backup data.

Thanks! This is all new, so pardon my lack of knowledge here. If I can provide any more information let me know.

We are retiring a hosted application for an electronic health care records (EHR) system which stored the data on Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.2.2 (Build 867_4_20245) Thu Oct 8 2020 16:58:40 EDT. The hosting company is providing me with a single CBK file. I need to install a database system to restore the database and provide occasional SQL access for reports when necessary. I'll need to maintain access to the data for an approximately 10 year retention period. Not sure how to approach restoring this old of a database and eventually upgrading it to a newer re

Hello Everyone,

We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.

Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.

First Patching:

So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).

I have set up a Docker image with IrisHealth Community Edition and created a backup of all databases with the Management Portal. Obviously, the restore requires a different way, i.e. a terminal or session needs to be started to use a "Do ^DBREST".

Due to the manual first a session (which is probably same as iristerm terminal) needs to be started:

docker exec -it iris iris session iris

If I enter "DO ^DBREST", I get the answer:

I have been trying to do a backup from tape using the D ^DBREST command. I am not able to connect to the tape drive, that recently got replaced. It is configured and I can see it with IBM's ITDT. I did a test and it came back with the error below:

Are there any suggestions on how to fix this or what commands to use to get this opened and connected? I do appreciate it.

In this article, we’ll build a highly available IRIS configuration using Kubernetes Deployments with distributed persistent storage instead of the “traditional” IRIS mirror pair. This deployment would be able to tolerate infrastructure-related failures, such as node, storage and Availability Zone failures. The described approach greatly reduces the complexity of the deployment at the expense of slightly extended RTO.

After any installs upgrades we get the following

04/13/23-18:00:00:978 (18668) 0 [Utility.Event] d:\intersystems\healthshare\mgr\enslib\ (Database is readonly)
04/13/23-18:00:00:979 (18668) 0 [Utility.Event] d:\intersystems\healthshare\mgr\hslib\ (Database is readonly)

I think we must have before altered these to not read-only.

Not sure if the isssue is by default

-Running task as user with %ALL rather than SYS user

- Should the dbs be as default in the all backup list

- Should these be not ro so it backs up without error?

InterSystems FAQ rubric

You can use the system routine ^DBSIZE to estimate the backup file size (see also Note 1).

^DBSIZE estimates the file size of full, cumulative, and differential backups of the databases selected in the database backup list.

The database backup list is created from [System Administration] > [Configuration] > [Database Backup] > [Database Backup List] in the Management Portal.

Restoring a backup

I have a client who' recently acquired a business that was running software that uses InterSystems IRIS as the database back end. In the process of preparing to have my company's software installed the client formatted the hard drive of his server, wiping out his data. I can't convert the data to MS SQL without a functioning database. He had a backup on an external drive, which I have copied down to my local machine. I loaded up a virtual machine with Windows 10 Pro, I installed Docker and IRIS. I started searching for explicit instructions for restoring the .CBK file, but I'm not hav

I am looking for experience of people running Veeam with Caché databases.

Tips/Tricks/General questions like; what Veeam features are you using, what your backup cycle looks like, where does your data end up, what recovery/integrity checks you do, what sort of compression/dedupe you get.

Also what questions _you_ have and what problems you might be trying to solve.

Working in support, I usually get asked how many days I should keep journals. Should it be two days or after two backups? More? Less? Why two?

The correct answer (for most of the environments) is that you should keep the journals since the last validated Backup. I.e., until you don't check if a Backup is valid (restoring the file and checking with the Integrity utility), you can't be sure there is a good copy of your data and can't purge the journals safely.

Hey everyone.

I have been revisiting our backup strategy, and spotted that IRIS supports VSS (Volume Shadow Copy Service) in Windows. This is quite attractive as an approach, as it automatically calls the external freeze and thaw commands.

However when calling these manually, there's quite a few parameters that can be set, and the documentation around VSS only states that the freeze/thaw commands are called.

Is there a way of controlling the parameters used, or at the very least know what the defaults are?

Currently running on limited hardware, Online Backups are becoming a bottleneck for our system.

For now, we are exploring an option to backup individual databases, or groups of them, thus reducing RAM requirements per individual backup task. To do that, however, we'd need a separate Backup List for our Backup Tasks. We did not find an option to do so in web portal, so currently we are looking at inheriting from system backup tasks and Backup.General classes to generate Backup List before backing up and then performing the backup as normal.
