Best Backup Technology + Small UI Wish for Separating Technologies vs. Providers

[timka]

Is there a technology you prefer for network-based deployments (where no physical/direct access to the server is possible)? For example, would you recommend SSHFS, S3-compatible storage, or something else for remote backup scenarios?
I would appreciate some personal opinions

Also, @girish regarding the backup setup: it might improve usability if the storage provider list were divided into technologies (self-hostable/generic protocols) and providers (cloud services). Perhaps a simple separator like --- could visually split the dropdown:

CIFS Mount
External/Local Disk (EXT4 or XFS)
EXT4 Disk
Filesystem
Filesystem (Mountpoint)
Minio
NFS Mount
S3 API Compatible (v4)
SSHFS Mount
XFS Disk
