Nightly restic backup takes nine hours and the repo grew 400GB in a month

The database dumps, near certainly. A full dump written as a fresh file every night deduplicates badly because compression changes the byte layout of the whole file even when 99 percent of the data is identical. If they are compressed dumps, that is your 400GB. Two fixes: dump uncompressed and let restic handle the compression and dedup, or use a format that produces stable output. People are always surprised how much a 10GB nightly dump costs over a month.
