Backup and Restore GuideThe Informix® Backup and Restore Guide describes how to use the Informix® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
ontape backup and restore system
Configure ontapeYou configure the ontape utility by setting configuration parameters for backups of storage spaces and logical logs.
Set configuration parameters for the ontape utilityThe ontape utility uses eight configuration parameters in the onconfig file. Two of the configuration parameters specify filter programs for transforming data during backup and restore; the other six are used to create storage-space and logical-log backups.

Specify a file system directory

Specify a file system directory

You can perform a storage-space (level 0, 1, or 2) archive, or a logical-log backup to a directory in the file system by using the ontape utility. For each storage-space archive and logical-log backup, ontape creates a file in the specified directory.

To specify a file system directory, set the LTAPEDEV and TAPEDEV configuration parameters to the absolute path name for the directory.

When ontape repeats an archive operation, it renames the existing files so that old files are not rewritten. A timestamp is added to the file name, which provides a way for related storage space or logical log files to be organized together.

To learn about the file naming schema, see Rename existing files.
