Ransomware protected backup
Posted: Sun Feb 10, 2019 5:55 pm
Hi,
So, my home server was attacked yesterday by a ransomware and around 2TB worth of personal files got encrypted. Thankfully, I have an offline backup (external disk) and my QNAP NAS was also spared that has another backup on it. So ransom guy can do one to himself.
So, going forward, I would like to setup a backup from my QNAP drive to an attached USB. I know I can do this today (been doing it). However, I have a few questions:
- Is versioning available in QNAP backups? I am thinking I would like to keep 3 months of versions.
- Is snapshoting available to USB? The reason I am asking about this is that, I have around 50-60K personal family pics. It would be extremely time consuming to revert them to a previous version if another attack were to occur. Perhaps reverting back to a previous snapshot might be a bit easier. May be a daily differential snapshot and weekly full one?
- Is there a way so that USB drives attached to the NAS unit can only be used by the backup process and not be accessed remotely using any login (even admin login). This is to prevent any infection to backups.
Thank you for any help and suggestions.
