FUCKING STACKOVERFLOW ASSHOLES.

This guy answered my question on security.stackexchange.com with an answer showing he clearly doesn’t understand that I’m asking if my RAID1 setup constitutes an appropriate backup. (I know that sounds stupid, I can post a link if anyone wants to see the specific circumstances).

I FUCKING KNOW RAID ISNT A BACKUP BUT THIS GUY IS LIKE “RAID 1, or mirroring, is definately [sic] considered a backup in corp IT”

Go suck a dick.

    I don't get it...
    What did you want to hear then?

    Is a protection against silent data corruption and a software raid used?

    I’m wondering if storing two copies of something on the same RAID1 array is appropriate as a backup

    RAID1 is in no way considered a data-backup, it's a hardware backup. It safes you if hardware fails. If tbe OS decides to fuck up your filesystem, you're doomed. If malware decides to delete half your files, you're doomed. If Angela from Finances decides to replace the monthly overview with a big ass excel rainbow, you're doomed. If ransomware encrypts your data? You're fucking doomed. If your server room burns down, you're still doomed. If your raid controller fucks up, you're doomed.
    A raid is part of the solution, but not a solution itself. It serves to have a fallback if specific hardware goes bad, nothing more

    @Kimmax exactly.

    What I’m talking about is having a RAID array as like an external drive and storing two copies of the data on the same drive array to protect against user error

    @DeveloperACE no. Raids will always share the data somehow over multiple drives, I'm not aware of something like a delayed RAID1. if the user error happens, it's immediately written on the devices, depending on configuration. Your usb drives wouldn't write simultaneously. That's the difference

    @DeveloperACE alright, read the question. So here it goes: Yes, two partitions on a raid1 with _manual_ coppied of the data does protect against user error, but nothing more. Malware could access both copies directly. However the two copies on the raid are still vulnerable to a hardware errors, except for one drive failing. If one drive fails, you would be covered. If the raid controller fails and decides to write shit you're doomed.

    @Kimmax add that as an answer!
