New to Trusted Platform Module. So TPM 1.2 or TPM 2.0? And what about RAID 1 drives?

(1) For comparison using tpm, check the following data for selection.

In the case of tpm I think it is well explained on the web. For security reasons, you can increase the security of your connection through your firewall and security settings, and if necessary, encrypt the disk itself. As there are so many choices for security, these security issues are used in combination.

(2) Please use raid 1 because raid0 may have a problem with recovery. raid0 can be quick access and extend storage capability, but I do not recommend it if you need stability.

(3) I asked the same question for one. raid1 can be restored in case of disk problems. However, it is not perfect if it is a soft raid setting, and if it is important equipment, it is set and used by hardware raid card. I usually use raid5 or higher to apply the system, and more stable if I use raid 10

(4) If it is expensive, it can be economically managed by storing it on another storage device using an unused computer, and it is also desirable in terms of resource management. We do not have to stick to the latest equipment, and if you simply use a Fedora server to configure a file server, you can replace expensive equipment at a fraction of the cost.

(5) If you store valuable information over a long period of time, you can easily recover information in the event of an accident by installing a separate backup device in addition to the basic storage device. Likewise, important data is stored on a separate server, and such servers may even separate the network and power.
