The task is as follows, there is a hypothetical hosting machine, on it a bunch of all sorts of services for the account hangs: apache, mysql, etc. etc. - it doesn’t matter, in general, a common hosting unit.

It is necessary to organize hard drives in such a way that it would be productive and safe.
I came up with the following configurations:

First configuration of 2 disks.
1) system files + data (2 partitions)
2) backup + temporary

According to garlic, 3 disks are better and therefore there is a second configuration
1) system + temporary
2) data
3) backup

This is the first time I've come across this issue. Please, tell me which is better or better. Maybe I'm just overthinking something. I will say one thing u1 with 3 disks is a little bit somehow in nature. I can also explain that there is still not enough money for a backup server. Maybe you have better ideas or experience.

Thank you for your attention.

UPD:
Idea from Anatole
Third configuration
1 + 2) RAID-1 system, data, temporary, partitioned backup.
Fault tolerance, downtime mineralization at the server, if a disk has crashed, replacement is carried out as planned.

Two disks in RAID-1 (mirror) with a separate partition for backups plus dumping backups somewhere like dropbox and don't worry. And you also need to monitor the state of the array in order to replace the disk on time, if anything.

Better 3 disks, the first 2 - in RAID1. And stick the 3rd disk into another server. In another country.

The other day, I lost 3 1.5TB screws at once, 2 of them were in a mirror raid in one machine, the third was on a separate machine with backups ... I
hoped that it would be almost impossible to fail them at once ...
I also have a web server on it only 1 screw per 1TB and backups and everything on it and lies for 3 years, a year ago I started uploading backups with rsync'om to a separate backup server.
the other day I looked at the SMART of this screw and oh, it's also on the verge of death.
