Hi all,
As self-hosting is not just “home-hosting” I guess this post should also be on-topic here.
Beginning of the year, bleeping-computers published an interesting post on the biggest cybersecurity stories of 2023.
Item 13 is an interesing one. (see URL of this post). Summary in short A Danish cloud-provider gets hit by a ransomware attack, encrypting not only the clients data, but also the backups.
For a user, this means that a senario where, not only your VM becomes unusable (virtual disk-storage is encrypted), but also the daily backups you made to the cloud-provider S3-storage is useless, might be not as far-fetches then what your think.
So … conclussion ??? If you have VMs at a cloud-provider and do daily backups, it might be usefull to actually get your storage for these backups from a different provider then the one where your house your VMs.
Anybody any ideas or remarks on this?
So … conclussion ???
Have backups.
Only 2 copies of your data stored in the same place isn’t enough, you want 3 at minimum and at least 1 should be somewhere else.
Indeed. Whatever you put in a cloud needs backups. Not only at the cloud provider, but also “at home”.
There has been a case of a cloud provider shutting down a few months ago. The provider informed their customers, but only the accounting departments that were responsible for the payments. And several of those companies’ accounting departments did not really understand the message except for “needs no longer be paid”.
So for the rest of the company, the service went down hard after a grace period, when the provider deleted all customer files, including the backups…
What if the data is leaked/compromised?
That’s why you use encryption.
Backups are usually encrypted from most popular backup programs, either by default or as an option (restic, borg, duplicati, veeam, etc…). So that would take care of someone else getting their hands on your backup data.
I never store my actual files on a cloud service, only encrypted backups.
For local data on my devices, my laptop is encrypted with bitlocker, and my Android phone is by default. My desktop at home is not though.
