+  - `MAX_CONCURRENT_BACKUP_COMPRESSION_TASKS` is how many backup compression tasks can run at the same time. Limiting concurrent compression tasks limits memory usage of compression, but it increases time between backups because the next backup is only scheduled once the current one completes. Default: `1`
