For a system with a very tight disk space, this setting is undoubtedly helpful. But from the database's own health and performance considerations, this setting is not recommended for multiple use. This is because:1. SQL Server will grow automatic

Their backup order (a, C, B, a) reflects the business requirements of the database.Under the full recovery model, restoring a filegroup backup requires not only restoring the filegroup backup itself, but also restoring all log backups from the last full database backup to the target point in time of recovery. To ensure that the file remains consistent with the rest of the database. So the number of transaction log backups to recover will be large. To avoid this scenario, consider usi
