Rotation Schemes Rotation Schemes This section describes how to configure a rotation scheme for a backup job by using the BrightStor ARCserve Backup default scheme or by specifying your own rotation parameters. To access the parameters for configuring a rotation scheme, select the Schedule tab in the BrightStor ARCserve Backup Manager. The parameters that you can use are described in the following sections. ■ Scheme Name-Select the type of rotation scheme you want, based on 5 or 7 day, and incremental, differential, or full backups. For more information on these standard schemes, see Calendar View in this chapter to modify your rotation scheme. ■ Start Date-The date the backup will start. ■ Execution Time-The time the backup will start. ■ Retry Missed Targets-To back up any missed target drives, enter a specific time that the job will repeat. ■ Enable GFS-BrightStor ARCserve Backup allows you to select from pre-defined Grandfather-Father-Son (GFS) rotation schemes consisting of full weekly backup jobs combined with daily incremental and differential jobs. The GFS strategy is a method of maintaining backups on a daily, weekly, and monthly basis. Accessible from the Backup Manager, the primary purpose of the GFS scheme is to suggest a minimum standard and consistent interval to rotate and retire the media. The daily backups are the Son. The last full backup in the week (the weekly backup) is the Father. The last full backup of the month (the monthly backup) is the Grandfather. GFS rotation schemes allow you to back up your servers for an entire year using a minimum of media. GFS backup schemes are based on a five or seven-day weekly schedule beginning any day. A full backup is performed at least once a week. On all other days, full, partial, or no backups are performed. Using GFS rotation, you can restore data reliably for any day of the week by using the weekly full backup in conjunction with the daily incremental or differential backup jobs. Note: A five-day GFS rotation scheme requires 21 media-per-year, while a seven-day scheme requires 23 media-per-year. Although GFS rotation schemes are predefined, you can modify these schemes to suit your individual needs. You can deviate from your standard rotation scheme (for instance, if a holiday falls on Wednesday, your usual backup day). 5-2 Administrator Guide

Rotation Schemes
This section describes how to configure a rotation scheme for a backup job by
using the BrightStor ARCserve Backup default scheme or by specifying your own
rotation parameters. To access the parameters for configuring a rotation scheme,
select the Schedule tab in the BrightStor ARCserve Backup Manager. The
parameters that you can use are described in the following sections.
Scheme Name—Select the type of rotation scheme you want, based on 5 or 7
day, and incremental, differential, or full backups. For more information on
these standard schemes, see
Calendar View
in this chapter to modify your
rotation scheme.
Start Date—The date the backup will start.
Execution Time—The time the backup will start.
Retry Missed Targets—To back up any missed target drives, enter a specific
time that the job will repeat.
Enable GFS—BrightStor ARCserve Backup allows you to select from
pre-defined Grandfather-Father-Son (GFS) rotation schemes consisting of full
weekly backup jobs combined with daily incremental and differential jobs.
The GFS strategy is a method of maintaining backups on a daily, weekly, and
monthly basis.
Accessible from the Backup Manager, the primary purpose of the GFS scheme
is to suggest a minimum standard and consistent interval to rotate and retire
the media. The daily backups are the Son. The last full backup in the week (the
weekly backup) is the Father. The last full backup of the month (the monthly
backup) is the Grandfather. GFS rotation schemes allow you to back up your
servers for an entire year using a minimum of media.
GFS backup schemes are based on a five or seven-day weekly schedule
beginning any day. A full backup is performed at least once a week. On all
other days, full, partial, or no backups are performed. Using GFS rotation, you
can restore data reliably for any day of the week by using the weekly full
backup in conjunction with the daily incremental or differential backup jobs.
Note:
A five-day GFS rotation scheme requires 21 media-per-year, while a
seven-day scheme requires 23 media-per-year.
Although GFS rotation schemes are predefined, you can modify these schemes
to suit your individual needs. You can deviate from your standard rotation
scheme (for instance, if a holiday falls on Wednesday, your usual backup day).
