Disk Storage Unit Considerations

A disk type storage unit consists of a directory on a hard disk that stores the backup or archive data. NetBackup permits an unlimited number of disk storage units.

A disk type storage unit is useful for testing and is useful during busy periods because it allows quick backups. However, you must be careful that it does not fill up your disk.

Before using a disk storage unit, configure the disk as explained in your operating system documentation. To calculate the approximate disk space that NetBackup requires as it creates backups, use the following formula:

(Largest backup size x (number of backups + 1)) + Space for the restores that are concurrent with backups
