RAID 1. Raid 0 stripes data between disks, meaning you get much faster I/O speeds but if one disk fails, you lose it all. RAID 1 is when you have 2 (or more) disks and the data is mirrored between both. So if one does, you’ve got a perfect copy of it on the other disk.
RAID 0 = “striped”, RAID 1 = “mirrored”
For availability, yes, but RAID is not a substitute for proper backup procedures. E.g. - offsite, cloud, or automated scheduled backups, or even regular data integrity checks.
And that’s why RAID is a good idea.
Raid 0 right?
