Backup

Introduction

Despite the fact that InterSystems has long recommended using external backup tools, many users have opted to use the internal Online Backup facility, which is included in all distributions of InterSystems products (IRIS Data Platform, Caché, etc.). The reasons why are quite obvious:

The goal of this writing was to illustrate how to restore backup before the patch would be applied. The alert notes that: 

The risk can be avoided by applying journals from the beginning of the journal file that was switched to at the start of the backup, rather than accepting the default of starting from the journal marker position.

Having non-patched Caché 2015.1.4, I ran sample database backup and restore just to get where I should answer "No". Collecting journal info from the backup log: 

Between Aix(backup) and Windows(recovery) , How to do this?

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.

Database systems have very specific backup requirements that in enterprise deployments require forethought and planning. For database systems, the operational goal of a backup solution is to create a copy of the data in a state that is equivalent to when application is shut down gracefully.  Application consistent backups meet these requirements and Caché provides a set of APIs that facilitate the integration with external solutions to achieve this level of backup consistency.

Hi,

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.

Hi Everyone,

I am using IRIS for health  in two different machines. In want to export the data from Machine 1 IRIS instance in which license is expired already.

In Machine 2 i activated new license. Now i need to import the Machine 1 IRIS data into Machine 2 IRIS.  

Thanks,

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 implementing the Data Innovations Instrument Manager product.  In setting up our backup process we are wanting to use Veam snapshots. The application runs in a Caché 2016.1/Windows Server 2016 instance.  We are running an HA primary/secondary/arbiter config. The statement below is from DI.  I am curious to see what others that have implemented the DI Instrument Manager in the same or similar config have in place for backup.

"DI recommends is recommending that we not perform snapshots, but if you do choose to do so, here is some important information to consider.

Currently we are using Health Share 2015.2.2, and looking to upgrade to the latest version in the next month.

From what I understand we have to upgrade to 2017 or 2018 prior to going to 2019.1 since 2019.1 is on the IRIS platform.

In trying to outline my steps in the upgrade process I came up with a question.

• Can a Full System Backup from 2015.2.2 be restored into 2019.1?
• Do I have to restore the 2015.2.2 back up into 2017 or 2018, then do the 2019.1 conversion?

Has anyone had experience with this? or should I open a ticket with WRC?

I have a FullBackup.cbk file generated by Caché Backup Online. This file has many databases.
Is there a Caché feature to restore only one database?

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.

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.

How would you do it?

Hi All!

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?
