Anki algorithm's is extremely punishing, which is awful for language learning.
I think SRS needs to be only a small part of the learning routine, the cherry on the cake. For me that is ~15 minutes / day, and backlog is manageable even if I occasionally take 2-3 days off.
The new Anki FSRS algo lessens this punishment significantly.
People focus way too much on the backlog - don't even look at it, just set your max cards per day to something you can actually DO and let Anki schedule them out as best it can.
