The [PersistentDb] section of the JADE initialization file can now contain the BackupCompressedFileGrowthIncrement parameter, which has a default value of 1G. This parameter specifies the size of the increment by which a backup file increases during a compressed backup.
If the value supplied is not a multiple of the value of the BackupBlockSize parameter, it is rounded up to the next highest multiple.
The minimum value is 64M bytes. If the file to be backed up is smaller than the value of the BackupCompressedFileGrowthIncrement parameter, the backup file is pre‑allocated to that size. The maximum value is 64G bytes.
