VeeamON Resiliency Summit 2023

On October 24, 16:00 CEST, the VeeamON Resiliency Summit will take place, streamed live online worldwide. We can look forward to the announcement of the Veeam Data Platform 23H2 update.

Furthermore, there will be three tracks of breakout sessions focusing on Veeam Data Platform, Veeam platform extensions and Veeam partner ecosystem.

The Veeam Data Platform 23H2 update includes the latest resiliency features of Veeam Backup & Replication V12.1, Veeam ONE V12.1 and Veeam Recovery Orchestrator v7, as well as updates to AWS v7, Azure v6 and Google v5.

Registration


It’s definitely worth registering, even if you can’t watch the stream online live, as the content will be available on demand later.

Veeam – Manage your AWS Data like a Hero

IDC research shows that the top three trigger events leading to a need for cloud services are: growing data, constrained IT budgets and the rise of digital transformation initiatives. The shift to public cloud providers like AWS offers many advantages for organizations but does not come without risks and vulnerabilities when it comes to data.

Veeam has provided several small comic book eBooks that illustrate issues such as ransomware, data sprawl, cloud costs, and data loss in an entertaining way.

Activate Immutability flag on existing Veeam XFS Repositories

Veeam Backup & Replication v11 is about to be launched on February 24th. Partners and service providers already have access to the RTM build.

One of my favourite features of version 11 are immutable backup files. You can read about it in my recent post “Hardening your Veeam Backup strategy with immutable repositories on Linux XFS“.

Some of you might already use Linux repository servers based on XFS with fast clone. Once you upgrade to Veeam Backup & Replication version 11 you may wish to activate immutable backups. I will explain in this blog post how you can use this new feature on existing XFS repository servers.

Activate immutability

To activate the immutability feature edit your existing backup repository servers and go to step “repository” (picture below). Starting with version 11 there’s a checkbox “make recent backups immutable for [x] days” where 7 is the minimum value to enter. Once you activate the checkbox you will most likely see a message “Unable to set the immutability option: cannot find the transport service on server <your repo server>. Configure the server anyway?“. Click on [Yes].

To make use of the immutability flag you’ll have to reconfigure the transport service on the Linux server.

Hardening your Veeam Backup strategy with immutable repositories on Linux XFS

Attackers on IT infrastructure have become more sophisticated in recent times. Not only do they ecrypt live data and entire virtual machines, they also have learned to delete or encrypt entire backups too. No matter if your online backups are stored on a local repository or a cloud share. If that happens and you do not have an offline backup like tape or any other air gapped solution you’re up a creek without a paddle. Even worse: If you’re responsible for data backup, you might be facing unpleasant questions by the management.

Now the question is how to protect backup data in case an attacker gets hold on your backup server. Once they get credentials to the server, they can do whatever the backup-admin can do. Deleting backups for example. One first step is to separate your backup systems from your domain. In case the domain administrator account gets compromised there’s still (a little) barrier between attackers and your backup systems. But still, you’ll never know if attackers have knowledge of a zeroday exploit to takeover your backup server. It would be a better approach to protect backups against deletion for a defined timespan. There’s a similar option on AWS S3 buckets, which are usually used as offsite backup copies. Getting back offsite backups takes a considerable amount of time. In case of a crypto attack time is crucial and the clock is ticking. Wouldn’t it be great to have immutable backups on your primary repositories on site? Good news. There’s light at the end of the tunnel (and I promise it’s not the oncoming train).

Immutable Backups

Before we go into detail, we need to clarify what immutable backups mean. The idea is that you write once and then files (backups) are protected for a self defined period of time. Even the backup administrator cannot delete them before the defined timespan has passed.

Veeam Backup & Replication v11 will make use of a native Linux XFS filesystem feature. XFS can set an extended file attribute [i] which will protect the file from renaming, modification, deletion or hard-linking. The key point is that backups are transferred and written with non-privileged accounts and the immutable attribute is set and removed by a privileged service on the repository server which cannot be accessed from outside.

All you need is a Linux repository formatted with XFS and Veeam Backup & Replication v11, which will be released in the near future. (Update: Expected release date will be February 24th 2021)
