The correct answer to the question is A. full backup method.

A backup is the process of creating a copy of data that can be used to restore the original data in case of data loss. There are several types of backup methods, including full backup, incremental backup, differential backup, and tape backup.

Full backup is a backup method that creates a complete backup of all data, files, and folders on the system. It is the most comprehensive backup method and ensures that all data is backed up. A full backup is primarily run when time and tape space permits and is used for the system archive or baselined tape sets. Since it backs up all data, it takes the longest time to complete and requires the most storage space. However, a full backup is the easiest and quickest method to restore data, as it only requires one tape to restore all the data.

Incremental backup is a backup method that creates a backup of data that has changed since the last backup, whether it was a full backup or an incremental backup. Incremental backups take less time and require less storage space than full backups, but they require all previous backups to be restored to recover the data fully.

Differential backup is a backup method that creates a backup of data that has changed since the last full backup. Differential backups take less time and require less storage space than full backups, but they require the last full backup to be restored along with the latest differential backup to recover the data fully.

Tape backup is a backup method that uses tape drives to store the backup data. Tape backup is an older backup method that has been largely replaced by disk-based backup systems. Tape backup takes longer to complete and requires more storage space than disk-based backup systems, but it is still used in some organizations that require long-term data retention.

In conclusion, the backup method primarily run when time and tape space permits, and is used for the system archive or baselined tape sets is the full backup method.
