Description

Specifies the type of backup options.

TFDADSBackupOptions can have one of the following values:

Value Meaning

boMetaOnly

Use it if you only want to back up the data dictionary file.

boPrepareDiff

Use it if you want to initialize a differential backup.

boDiff

Use it if you want to perform a differential backup on a database that you have previously initialized using boPrepareDiff.

boCompressArchive

Use it if you want to perform a backup where the resulting archive file is compressed. This can result in a much smaller backup image.

Notes:
  • Backups of encrypted tables may not lead to a great space saving. This is because encrypted data compression is not straightforward.
  • If you use this option for the backup, you will need to use it when specifying the restore options.
