Tape and tape device parameters for ontape

The first set of configuration parameters specifies the characteristics of the tape device and tapes for storage-space backups; the second set specifies the characteristics of the tape device and tapes for logical-log backups.

The following list shows backup tape devices and their associated tape parameters.
TAPEDEV
The absolute path name of the tape device or directory file system that is used for storage-space backups. Specify the destination where ontape writes storage space data during an archive and the source from which ontape reads data during a restore.

To configure ontape to use stdio, set TAPEDEV to STDIO.

When backing up to or restoring from a cloud environment, use the following syntax for the TAPEDEV configuration parameter:
TAPEDEV 'local_path, keep=option, cloud=cloud_vendor, url=url'
  • local_path is the complete path name of the directory where storage spaces backup objects are stored temporarily.
  • option can be set to yes or no. If keep is set to yes, the ontape utility retains the backup objects in the local directory. If keep is set to no, the backup objects are deleted after they are transferred to or from the cloud storage location.
  • cloud_vendor is the name of the cloud storage vendor.
  • url is the cloud storage location where the storage space backup data is stored persistently.
TAPEBLK
The block size of the tapes used for storage-space backups, in kilobytes.
TAPESIZE
The size of the tapes used for storage-space backups, in kilobytes.
The following list shows the logical-log tape devices and their associated tape parameters.
LTAPEDEV
The logical-log tape device or a directory of a file system.
When backing up to or restoring from a cloud environment, use the following syntax for the LTAPEDEV configuration parameter:
LTAPEDEV 'local_path, keep=option, cloud=cloud_vendor, url=url'
  • local_path is the complete path name of the directory where log backup objects are stored temporarily.
  • option can be set to yes or no. If keep is set to yes, the ontape utility retains the backup objects in the local directory. If keep is set to no, the backup objects are deleted after they are transferred to or from the cloud storage location.
  • cloud_vendor is the name of the cloud storage vendor.
  • url is the cloud storage location where the log backup data is stored persistently.
LTAPEBLK
The block size of tapes used for logical-log backups, in kilobytes.
LTAPESIZE
The size of tapes used for logical-log backups, in kilobytes.
