#Backup

Hi,

I'm trying to run some scripting in Windows. I'm using an instance of the IRISHealth community. 

I'm just trying to run a simple sequence of commands so I can run irissession in a non-interactive mode, like:

irissession.exe IRISHEALTH -U "%SYS" < "myprogram.iris"

set $namespace="%SYS"
set cbk = "C:\Test1.cbk"
set log = "C:\Test1.

At the moment, we have 10 HealthShare instance servers (5 x mirrored pairs), where we implement an External Backup approach, using the freeze/thaw commands against whichever server of the pair is the backup mirror member, to complete a VM level backup. These backups are stored to a disk within our control, to purge as required. This approach allows us to deliver a zero downtime backup approach.

Hi all,

I'm reviewing an older Cache routine and came across this line of code: from file ^ZDBKCRON

S $ZT="^%ETSDK"

Error trap

/home/oper/script/cache_db_backup -t        # Daily CacheDB Backup

 produced the following output:

 <NOROUTINE> *%ETSDK
<ERRTRAP>

-----------

From what I understand, this is setting up an error trap, but I'm not entirely clear on how it works, especially in modern InterSystems IRIS environments.

Could someone please help explain:

1. What exactly does this line do?
2. Is %ETSDK a standard system routine? I can't find it in our environment.

I have two instances of IRIS, one is Production and another one is Staging (both managed by Docker) and I want to set up a full daily recover of the Staging server from a full backup of the Production server. I know how to do this manually using the DBREST utility, as well as how to make a copy of the database by making a full copy of the durable directory (however this option requires a full stop of the Production-database). What is the best way to automatically restore all databases from a full backup using scripting?

Hi experts, 

Please, I'd know how the best way to do freeze and thaw databases on windows.
I'll do freeze databases before snapshot and thaw after snapshot.
I think is necessary execute scripts. Please, do you know where can I found it?

Thank you.

A customer is using Caché online backups and needs to automatically purge the cbk files with a scheduled task.

This is a wheel has been reinvented uncountable times already and I know somebody out there has a well written, extremely robust version that has already stood the test of time.

Does anyone have a nice routine/class/task for purging old Caché backup files? 

Hello,

While doing research on the upgrade to InterSystems IRIS 2024.1.2 version, I was wondering if it would be possible to rollback the installation and return to the previous version in case something went wrong ?

I didn't see anything talking about this in the documentation and when I tried to re-install an older kit over an upgraded instance, I couldn't use it.

Thank you in advance for your reponse

Customer is trying to use Veeam as backup of Cache database and we need a script to freeze (quiesce) the database for a clean snapshot. i am looking if there is a script already done.

Hey,

since our instance of iris is just utilized during working hours, I would like to simply copy all data via FTP from the server to a NAS during the night.

Are there reasons against this approach?

Are there batch examples of how to stop and start the database?

Thank you in advance!

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:

04/28/24-10:38:55:070 (6588) 0 Backup.General.ExternalFreeze: Suspending system
04/28/24-10:38:55:070 (6588) 1 Backup.General.ExternalFreeze: Warning, d:\test\databases\logic\ is not being journalled
04/28/24-10:38:55:070 (6588) 1 Backup.General.ExternalFreeze: Warning, c:\test\mprllib\ is not being journalled
04/28/24-10:38:55:085 (6588) 1 Backup.

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?

thanks,

Eyal

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.

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.

Good afternoon, everyone,

I would like to know if it's possible to restore a backup directly from a .DAT file, or if it's only possible to restore a backup made with a .cbk file?

Best regards, Flávio."

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.

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 tried using the code below in terminal to start httpd service for SERVER2 with no success.

I did not find any answer in the documentation and in the posts here to check if it also possible to migrate all databases from a native installed IRISHealth on Windows to my Community Edition in the container? Maybe anybody had tried this and can give me a hint.

Hello everyone,

I'm trying to perform a full backup using DO ^BACKUP, but the database keeps skipping the restoration. Does anyone know what I could do to allow the restoration?

Device: /usr/OLD/BACKUP.cbk
This backup volume was created by:
   IRIS for UNIX (Red Hat Enterprise Linux for x86-64) 2021.1
The volume label contains:
   Volume number      1
   Volume backup      AUG 21 2023 06:45PM Full
   Previous backup
   Last FULL backup
   Description
   Buffer Count       0
Is this the backup you want to start restoring?

Hello,

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:

<NOROUTINE> *DBREST.

I assume that when I start the session that way I get logged in as "USER", at least the prompt "USER>" indicates this.

Dear experts,

Please, how can I estimated completion time for backups and restores. Is there a script to run and estimated that time?
Thank you so much.

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.

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? 

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 .

Hi all,

Does anyone backing up with CommVault version 11 (but lets forget the version for now) and had problems using vss to backup Cache/Iris ?

Can you tell me what you did to overcome that problem/problems?

Thanks,

Hello everyone,

I want to restore a database from an external backup with the journal files.

The manual says I should (in short):

1. Stop journaling with ^JRNSTOP
2. Restore the database file IRIS.DAT
3. Run the journal restore utility with ^JRNRESTO
4. Restart journaling ^JRNSTART

Since I want to restore one database only step 1 would disable journaling for the whole instance, not only for the database to be restored. As I understand, it would be impossible to restore a different database if there occurs a problem while journaling is disabled during the recovery process?

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.

Hello gentlemen,

I hope you can help me because this is a very serious that I can't wait to resolve... Our back-up is currently taking 3 up to 4 Gb per day and we don't know why. We had 270 Gb yesterday and we are today at 274.3 Gb. We keep a computer history of the messages for only 50 days. Here is a picture of what's currently taking the most data place in our healtshare system:

(don't forget that our DB is also connected to the back-up, maybe it is related, I don't know)

Thanks you in advance,

Thomas

Hi

I have had customers who would rather use a backup application rather than using IRIS Backups. In my experience, I have tried a number of free backup tools and I have paid for at least two "very good Backup Tools" and all of them have failed to create usable backups especially if my Ensemble/IRIS Instances are still running and even if Ensemble/IRIS have been shut down I have found that the backups created by these tools have around an 80% chance of being able to restore a system (let's assume that I am not trying to backup core Windows elements like the Registry and Windows system files).

If I have an online backup running and a snapshot backup is run whereby a freeze/thaw is done, will the online backup be affected ?

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?
