    NAS With Non-Destructive Write Directories (to foil ransomware)


    Are there any NAS devices for home use which support what I'll call non-destructive write directories? So if I set up such a directory and write file XYZ it is written but does not destroy earlier instances of XYZ. If I read XYZ I get the latest instance written. If I want an earlier instance I have to read XYZdatetimestamp. Obviously this would not work well with frequently written large files. But it would work well for many files which want to protect.

    Thanks, Bob

    Hi there
    Any linux system is "Ransomware" resistant -- no computer on this planet (or probably anywhere in the known Universe) is 100% hackproof - but Linux is probably as good as it gets for home computers -- only authorised users can get access to the disks on the server in the first place and then they have to get WRITE permission.

    In any case Ransomware is hardly a problem these days on home computers -- Windows Defender plus the online protection is pretty robust these days - and if you use the usually pretty decent firewall systems in typical routers these days and check the logs refularly you can block inbound connections from "unknown sources" etc.

    Always have a clean image backup of your system -- Macrium free is good and create the stand alone recovery medium so you can boot the program from say a USB drive. then Ransomware will never be a problem.

    In case you do get any Ransomware notifications do the following at once

    1) Immediately HARD power off -- DO NOT USE Software Shutdown.
    2) Disconnect everything from that computer including any USB drives, ethenet connections etc
    3) switch router OFF -- so no Internet possibilty even by wifi. If that's not possible then OK but it's best to turn router off.
    4) boot stand alone recovery program with recovery media disk attached
    5) restore system
    6) re-boot
    7) restart router
    8) examine logs

    Cheers

    Hi Jimbo,

    Thanks for responding. Unfortunately I am not Linux literate and way too old/lazy to learn a new operating system. I am a Windows user and Windows has a permissions concept which probably would provide a layer of protection but, again, too old/lazy.

    But I do appreciate your response.

    Thanks, Bob

    Bob, I imagine Synology and Qnap have what you're looking for. Not sure how large you want to go. A 4 drive RAID 5 capable enclosure or something simpler like a 2 drive RAID 1 mirror.

    Synology Inc. - be sure to look at the Home NAS
    Master your digital files for work and daily life | QNAP (US) - same

    For Synology: Snapshot Replication | Synology Inc. - they have this functionality on their Home NAS devices

    For QNAP: TS-451+ - Features - QNAP (US) (scroll down to disaster recovery)

    But basically what you're looking for is some kind of versioning capability where you can go back in time.

    Conversely, you can get whatever NAS you like then subscribe to something like Crashplan (Cloud Data Backup for Small Businesses | CrashPlan) and have that back up your NAS. It has a relatively easy to use versioning restore system (you can go back to yesterday, 20 minutes ago, 30 days ago, etc.). When you go to restore files, you just pick a date on the calendar and, assuming it was successfully backed up that day, you can restore file(s) from that date in time.

    Hope that helps.

    Hi Chan, Thanks very much for your response. I ordered a Synology NAS yesterday (2 bay and I plan to use RAID mirroring). I didn't notice that they had Snapshot Replication but I will look into it.

    Thanks again, Bob
