In information technology, a backup, or the process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a data loss event.
In InterSystems Data Platform backup means procedures for backing up data in database files and all the related procedures which assure that no any application data is being lost during backup and recovery.
If I have a cache.dat file from a Windows 2012 (64-bit) machine and I want to mount it on a Caché instance running on RHEL, will it work? Assume the versions of Caché are the same.
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.
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?
I was understanding the cluster configuration supported by the Cache. Have couple of queries around that:
1. In Cache version 2018.2, there is a shrading concept which splits the data of a Master Data server into multiple small data server which store shraded data.
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.
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.
A site has a Mirror set, and an Asynchronous DR. The disk drives for each of the instances are local disks and the databases are large (>2 TB)
The current backup strategy is started off as using Cache Backup and is still the case today, but the size and time it take t do the backup is obviously prohibitive.
My project need to restore the previous part of the log, and I use the rountine "^JRNRESTO" and filter. After recovery completed, the table structure is restored, but the table data is not restored， also unable to insert data into the table.
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 created some roles, and would like to know if there is a way to export the Roles and save them off to a file? I want to create a backup file of these roles for DR purpose, and in case I ever get hit by the preverbal bus.
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?
We are trying to write an external backup application to backup Cache Database. After going through the Cache DB documentation, we have found that in Backup.General class there are methods for creating snapshot (Freeze/Thaw) which is required during backup. Are there REST APIs for the same?
Let's say you have about 100TB of data in multiple CACHE.DAT. The biggest one is about 30TB but mostly more than 1TB. You have limited time for maintenance during a day, and it is only a few hours at night. You have to check Integrity as much often as possible. And of course backup it.
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?
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?
I asked previously about the DR server in the cloud but actually, I'm curious about the backup server to use as analytics server more than for recovery in DR case.
There is a recommended practice to use an async mirror as a server for BI (InterSystems Analytics, DeepSee)
The question is if I have PRIMARY in the cloud (AWS, Google, Azure, etc) "how far" should async mirror member be placed? Same cloud, same private cloud or it doesn't matter at all for analytics purposes?
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?
We are trying to migrate all our production to new IRIS servers. To test everything is working fine, and to be able to script the process, we want to import the data into new IRIS servers using a backup file (created with ^BACKUP). But we've found that IRIS doesn't recognize Ensemble backups so we can't import it using ^DBREST :-O
Any of you know how to import in IRIS an Ensemble backup file?
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)
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?
We are currently using Ensemble on AIX. We are on 2015.2.2. If I install Field Test on a windows desktop, is it possible that I can import the Cache.dat from my AIX server, so I can do some Proof of Concept development?
