These options specify the default behavior for accessing a SmartLink (archived) file, if there is no file pool policy for the archived file. If there is a file pool policy for the archived file, that policy and its settings take precedence over any of these settings.
--default-accessibility {cached |
no-cache}
Specifies
cache to ensure that only the data blocks requested are cached and flushed or invalidated based on the cache retention settings. Specify
no-cache to ensure that the data blocks are not cached and do not consume file system blocks long term.
--default-cache-expiration<duration>
The minimum amount of time until the cache expires. A number followed by a unit of time is accepted. For example, a setting of 9H would specify a nine-hour duration. Similarly, a setting of 2D would specify a two-day duration.
--default-compression-enabled {yes |
no}
Specifies whether data is to be compressed when archived to the cloud.
--default-data-retention<duration>
The minimum amount of time that cloud objects associated with a SmartLink file will be retained in the cloud after the SmartLink file is deleted from the cluster. A number followed by a unit of time is accepted. For example, a setting of 9H would specify a nine-hour duration. Similarly, a setting of 2D would specify a two-day duration.
--default-encryption-enabled {yes |
no}
Specifies whether data is to be encrypted when archived to the cloud.
--default-full-backup-retention<duration>
The length of time that OneFS retains cloud data referenced by a SmartLink file that has been backed up by a full NDMP backup and is subsequently deleted. A number followed by a unit of time is accepted. For example, a setting of 9H would specify a nine-hour duration. Similarly, a setting of 2D would specify a two-day duration.
--default-incremental-backup-retention<duration>
The length of time that OneFS retains cloud data referenced by a SmartLink file that has been backed up by an incremental NDMP backup, or replicated by a SyncIQ operation, and is subsequently deleted. A number followed by a unit of time is accepted. For example, a setting of 5Y would specify a five-year duration.
--default-read-ahead {partial |
full}
Specifies the cache readahead strategy when SmartLink files are accessed. A partial strategy means that only the amount of data needed by the user is cached. A full strategy means that all file data will be cached when the user accesses a SmartLink file.
--default-writeback-frequency<duration>
The minimum amount of time to wait before OneFS updates cloud data with local changes. A number followed by a unit of time is accepted. For example, a setting of
9H would specify a nine-hour duration. Similarly, a setting of
2D would specify a two-day duration.
{--verbose |
-v}
Displays more information about the operation.

The following example modifies several of the default CloudPools settings:
