synology Replace Drives to Expand Storage Capacity

Need help with configuring a new synology NAS

Will be used for backups, in this case redundancy is not necessary (in my opinion) as it is not common both hard drives the computer and NAS to malfunction in the same time, and go with RAID 0 (Features "striping," a process of dividing data into blocks and spreading the data blocks across several drives in order to enhance performance).

But planing for the future, when want to expend and replace a hard drive with a larger drive, will this work with RAID 0, or will it need at minimum SHR, or RAID 1?

Ok going with Raid would you recommend Synology Hybrid RAID (SHR) or RAID 1?

SHR is just an interface over RAID interface as far as I understand it from its description. Which is designed for a person who does not have experience with RAID configuring.
If you don't have such experience then go with SHR.
Thank you again for your help, and last question going with SHR is it necessary or what type of benifit is when crating a disk group vr going direct to volume creation

From synology documentation;
Disk groups are composed of one or more hard drives combined into a single data partition. You can think of disk groups as the foundation on which one or more volumes can be built. Disk groups provide greater flexibility, allowing you to do the following:
Choose from various RAID types, depending on the number of hard drives installed.
Create a single, large volume, or create several volumes with customizable storage capacity.

A little more explanation would be a help. I don't get the benefit of a group, at least when using it as a backup destination with only two drives.

Like correctly stated above you get no benefit from a group. In the background it is the same like JBOD but Linux based. If you want to use this storage as location for your backups then I would recommend you using redundancy, where two drives are mirrored.
Thank you for your help.
