Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® 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 the tape sizeUse the TAPESIZE and LTAPESIZE configuration parameter parameters to specify the maximum amount of data that you can write to a tape.

Specify the tape size

Use the TAPESIZE and LTAPESIZE configuration parameter parameters to specify the maximum amount of data that you can write to a tape.

To write or read the tape to the end of the device, set TAPESIZE and LTAPESIZE to 0. You cannot use this option for remote devices.

When you specify the tape device as /dev/null, the corresponding tape size is ignored.
