Why would you want something specifically for photo/video when this solution can back up any file type or folder location?

Not the person who asked the question, but I'm guessing they might have a lot of the same photos and videos of different resolutions which would create files of different sizes.

There is and there isn't, in a sense that there's nothing better than general-purpose backup software. Media is almost always encoded in high-entropy formats thus negating any possible gains from incremental backups. So with common backup tools you only get data consistency checks and encryption, but almost no compression or intra-file deduplication, and to get that you need to reencode your media for storage, which is unfeasible, at least for now.

for phone backup I use immich, it's self hosted clone of Google photos. it's not best, does not work well with hdr photos/videos, but as just backup solution it have multiple ways to setup synchronization so you can choice your tradeoffs.
