Media Pools The following are the formulas used for calculating the number of media in the Save Sets and the retention times for the GFS media pools: ■ Daily pool-This pool holds the media for daily backup jobs. The default retention period is six days and the number of Save Set media is based on the number of daily media in the GFS Rotation minus one [# of daily media -1]. ■ Weekly pool-This pool holds the weekly media. The retention period equals the number of weekly media times seven, minus one [(# of weekly media * 7) - 1]. The number of save media is based on the number of weekly media in the GFS setup minus one [# of weekly media - 1]. ■ Monthly pool-This pool holds the monthly media. The retention period equals the number of monthly media times 29 minus five [(# of monthly media * 29) - 5]. The number of save media is based on the number of monthly media in the GFS setup minus one [# of monthly media - 1]. For more information on rotation schemes, including information on how to submit a rotation backup job, see the online help. Maximizing Media in GFS Rotation Jobs By default, BrightStor ARCserve Backup enables the Media Maximization option, which lets you submit multiple GFS backup jobs using the same media pool. By sharing the same media pool, you can append multiple jobs to the same tape sets rather than creating new tape sets for each job. This drastically reduces the amount of media you use when submitting GFS Rotation jobs. Note: To disable the Media Maximization option, set the NT registry DWORD value EnableMediaMaximization to 0. This registry key is located in HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\ BrightStor ARCserve Backup\Base\Task\Backup. Rules for Media Maximization To take full advantage of the Media Maximization option, use the following guidelines when submitting GFS backup jobs using the same media pool: ■ Use the same Rotation Scheme-GFS jobs that use different rotation schemes may need different tape names. To ensure that multiple GFS jobs will share the media, use the same rotation scheme. ■ Start GFS jobs on the same day-The first day of a GFS job is a full backup. Jobs that start with different dates may not be able to share media during the first week. To ensure that multiple GFS jobs will share media during the first week, start GFS jobs on the same day. Otherwise, media sharing will begin after the weekend. Managing Devices and Media 7-15

Maximizing Media in GFS Rotation Jobs

By default, BrightStor ARCserve Backup enables the Media Maximization option,

which lets you submit multiple GFS backup jobs using the same media pool. By

sharing the same media pool, you can append multiple jobs to the same tape sets

rather than creating new tape sets for each job. This drastically reduces the amount

of media you use when submitting GFS Rotation jobs.

Note:

To disable the Media Maximization option, set the NT registry DWORD

value EnableMediaMaximization to 0. This registry key is located in

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\ BrightStor

ARCserve Backup\Base\Task\Backup.

Rules for Media Maximization

To take full advantage of the Media Maximization option, use the following

guidelines when submitting GFS backup jobs using the same media pool:

■

Use the same Rotation Scheme—GFS jobs that use different rotation schemes

may need different tape names. To ensure that multiple GFS jobs will share the

media, use the same rotation scheme.

■

Start GFS jobs on the same day—The first day of a GFS job is a full backup. Jobs

that start with different dates may not be able to share media during the first

week. To ensure that multiple GFS jobs will share media during the first week,

start GFS jobs on the same day. Otherwise, media sharing will begin after the

weekend.
