Therefore, by default, when backing up a database using compression , the Database Engine uses a pre-allocation algorithm for the backup file.

See all full list on docs. SQL Backup Master v4.

The successful compression is dependent upon two factors and they are described below: 1. WITH COMPRESSION GO Pay special attention to keyword Compression in the above syntax. This becomes very tedious and cumbersome after a while as every single time when we have to take backup we have to specify that particular command. The backup compression default option determines whether the server instance creates compressed backups by default. Expand Databases, right-click SQLTestDB, point to Tasks, and then click Back Up.

You can alter log shipping after its created using the SSMS GUI and I also see backup compression working as expected while I add data. It is especially true when you experience disk space problems.

Due to RMAN’s tight integration with Oracle Database, backup data that is already compressed by Advanced Compression remains compressed when it is written to disk or tape and doesn’t need to be uncompressed before recovery – providing an enormous reduction in storage and a potentially large reduction in backup and restore times.
