Media rotation strategies

Son. Uses the same media each day to run a full backup.

Grandfather. Uses multiple media, includes a combination of weekly and monthly full and daily differential or incremental backups, and provides backups for offsite storage.

Media overwrite protection levels

Full - Overwrites scratch media, which are media that contain data you are willing to discard, and recyclable media, which are media that are associated with media sets and have expired overwrite protection periods.
Partial - Overwrites imported media, which are media that was created by another installation of Backup Exec or some other backup product, and overwrite scratch media.
None - Overwrites all media, including those that have current overwrite protection
periods (allocated media).

Example of Media overwrite protection period

For example, suppose that you create a media set named Weekly with an overwrite protection period of seven days, and an append period of 0 days, and you schedule a full backup job to run each Friday at 20:00. When it is time for the full backup to run at 20:00 the following Friday, the job cannot run because the first backup job that ran the previous Friday did not complete until 21:10 p.m. The overwrite protection period for the Weekly media set still has 70 minutes remaining.
Typically, to prevent this situation, you would shorten the overwrite protection period to account for the amount of time a job may run. For this example, the scheduled job recurring at 20:00 can run if the overwrite protection period is set to 6 days instead of 7 days.

Backup Exec’s media management-2

Retired Media: Lists all media that you have taken out of service, usually because of an excessive number of errors. After a media has been associated with the retired media set, it is not selected for backup jobs by Backup Exec. It is still available for restore operations.

Scratch Media: all media that can be overwritten. New, blank, and erased media are automatically associated with the scratch media set

Backup Exec’s media management-1

A media set is a set of rules that manage media.
Media that are associated with a media set are allocated media. Allocated media have current append and overwrite protection periods.
Media that are associated with a media set, but have expired overwrite protection periods are recyclable media.
