Rotation Schemes GFS Rotation Jobs on File System Devices BrightStor ARCserve Backup supports using a GFS rotation scheme on File System Devices. A retention period for the media being used in the GFS rotation scheme can be determined using the following default retention cycle for a seven-day weekly rotation: Frequency Daily Weekly Monthly Total Number of Media 6 5 12 23 To run a rotation job beyond a year, a GFS rotation scheme requires 23 File System Devices to be created. These settings can be modified to meet your specific needs. Modifying the default values of the GFS rotation may change the number of FSDs required. Note: Previously, only local disks were considered FSDs. You can now create FSDs that are accessible through a network share using a Universal Naming Convention (UNC) path. For more information on using BrightStor ARCserve Backup Device Configuration to configure your disk or disk array as a FSD, see the BrightStor ARCserve Backup Getting Started. Because a GFS rotation job may be using local disk drives and drive arrays, users must first make sure that there is enough space on the particular file system to store all the data being backed up for the entire retention period. Creating file system devices on a boot partition is not recommended because a boot disk that becomes full can cause the operating system to function abnormally. Note: All file system devices need to be assigned to the same device group. For more information on configuring a device group to be used by the GFS rotation scheme, or on how to set up a GFS rotation job, see the online help. A configured GFS rotation job can run on a daily basis at a specified time. BrightStor ARCserve Backup utilizes file system devices similar to a physical tape. As needed on a daily basis, BrightStor ARCserve Backup moves tapes between the save sets and the scratch sets in the media pools, formats blank media, overwrites expired media, and tracks all operations in the database.

GFS Rotation Jobs on File System Devices
BrightStor ARCserve Backup supports using a GFS rotation scheme on File System
Devices. A retention period for the media being used in the GFS rotation scheme
can be determined using the following default retention cycle for a seven-day
weekly rotation:
To run a rotation job beyond a year, a GFS rotation scheme requires 23 File System
Devices to be created. These settings can be modified to meet your specific needs.
Modifying the default values of the GFS rotation may change the number of FSDs
required.
Note:
Previously, only local disks were considered FSDs. You can now create
FSDs that are accessible through a network share using a Universal Naming
Convention (UNC) path. For more information on using BrightStor ARCserve
Backup Device Configuration to configure your disk or disk array as a FSD, see the
BrightStor ARCserve Backup Getting Started.
Because a GFS rotation job may be using local disk drives and drive arrays, users
must first make sure that there is enough space on the particular file system to
store all the data being backed up for the entire retention period. Creating file
system devices on a boot partition is not recommended because a boot disk that
becomes full can cause the operating system to function abnormally.
Note:
All file system devices need to be assigned to the same device group.
For more information on configuring a device group to be used by the GFS rotation
scheme, or on how to set up a GFS rotation job, see the online help.
A configured GFS rotation job can run on a daily basis at a specified time.
BrightStor ARCserve Backup utilizes file system devices similar to a physical tape.
As needed on a daily basis, BrightStor ARCserve Backup moves tapes between the
save sets and the scratch sets in the media pools, formats blank media, overwrites
expired media, and tracks all operations in the database.
