How do you manage personal data backups e.g. photos and videos

Rsnapshot (https://rsnapshot.org/) and/or just plain rsync to a Linux machine running an md RAID5 array with LVM2 above the md array for creating/resizing/dropping partitions.

Just store them in a Synology NAS. The NAS has an app to sync the files to a free 5 TB google drive account that I was given.
