More often than ever, backup administrators are limited in the amount of time that they have to perform a backup. This is known as the "backup window". It is necessary to minimize backup windows in order to maintain system availability and productivity. In an effort to reduce backup windows, backups are often written to the fastest possible media which in most cases is local disk.
SBAdmin provides support for writing any backup to a local disk (including SAN, SCSI, IDE, SAS, and USB), or over the network to a disk on a remote backup server. This is known as a disk-to-disk (D2D) backup.
While backups to disk are the most efficient, the importance of disaster preparedness may require maintaining offsite copies of backups. After a backup to disk has been completed, SBAdmin provides a feature which will allow you to then copy the backup to alternate media. This alternate media can be disk or tape, on either a local or remote system. This is referred to as Backup Staging.
Backup retention policies help manage disk space by automatically expiring and removing older backups as they are replaced by newer backups of the same backup job. The retention policies may be based on the age of the backups and/or the number of backups that you wish to always retain. These policies may also be different for each backup configured.
