CloudPool Storage Target
|
cloud-pool
|
The
PowerScale administrative container for a cloud storage account.
|
Each CloudPool can refer to only one cloud storage account. You must create a cloud storage account before creating and configuring a CloudPool. A CloudPools and its cloud storage account must be the same type:
Dell Technologies
PowerScale,
Dell Technologies ECS Appliance, Amazon S3, Amazon C2S, Microsoft Azure, Google Cloud, or Alibaba Cloud.
|
Encrypt data before transfer
|
cloud-encryption-enabled
|
Specifies whether CloudPools encrypts data before archiving it.
The default value is
disabled
|
Cloud data is decrypted when it is accessed or recalled.
|
Compress data before transfer
|
cloud-compression-enabled
|
Specifies whether CloudPools compresses data before archiving it.
The default value is
disabled.
|
Cloud data is decompressed when it is accessed or recalled.
|
Cloud Data Retention Period
|
cloud-data-retention
|
The length of time that cloud files are retained after the files are fully recalled.
The default value is
1 week.
|
CloudPools cleans up local resources that were allocated for the SmartLink files. CloudPools also removes the associated cloud objects. This work is performed frequently, affecting only objects whose retention period expired.
NOTE:The system removes (garbage-collects) cloud objects when their SmartLink files and all local references including snapshots to them are removed. If a SmartLink file is backed up and the original SmartLink file is later deleted, associated cloud objects are deleted only after the retention time of the backed-up SmartLink file expires.
|
Incremental Backup Retention Period for NDMP Incremental Backup and SyncIQ
|
cloud-incremental- backup-retention
|
Specifies the length of time that OneFS retains cloud data that is referenced by a SmartLink file that was last replicated by SyncIQ or an incremental NDMP backup.
The default value is
5 years.
|
If a SmartLink file is backed up and the original SmartLink file is later deleted, associated cloud objects are deleted only after the retention time of the backed-up SmartLink file expires.
|
Full Backup Retention Period for NDMP Only
|
cloud-full-backup-retention
|
Specifies the length of time that OneFS retains cloud data that is referenced by a SmartLink file that was backed up by a full NDMP backup.
The default value is
5 years.
|
If a SmartLink file is backed up and the original SmartLink file is later deleted, associated cloud objects are deleted only after the applicable retention period expires.
|
Writeback Frequency
|
cloud-writeback-frequency
|
Specified the interval at which the system writes the data stored in the cache of SmartLink files to the cloud.
The default value is9 hours.
|
Specifies how often SmartLink files modified on the cluster are written to their associated cloud data objects.
|
Accessibility
|
cloud-accessibility
|
Specifies how data is cached in SmartLink files when a user or application accesses a SmartLink file on the cluster. Values are cached and no-cache.
The default value is
cached.
|
Determines whether cloud data is cached when a file is accessed on the local cluster.
- cached
- When
cached is selected, accessed cloud data is cached to the SmartLink file on read or write access.
- no-cache
- When
no-cache is selected, the system does not cache data in the SmartLink files on read access, but passes it through to the local accessing application. If you write to data accessed when this setting applies, the system caches your changes. Choose
no-cache if you want to limit the use of cluster resources.
|
Cache Read Ahead
|
cloud-readahead
|
Specifies the cache read ahead strategy for cloud files (one of partial or full)
The default value is
partial
|
Specifies whether cloud data is fully or partially retrieved when you access a SmartLink file on the cluster. If
partial is specified, the system only retrieves the file blocks needed when a SmartLink file is accessed. If
full is specified, all cloud data is fully cached when the SmartLink file is accessed.
|
Cache Expiration
|
cloud-cache-expiration
|
Specifies the number of days until the system purges expired cache information in SmartLink files.
The default value is
1 day.
|
Specifies how long the system retains cloud data that has been retrieved in the cache of associated SmartLink files.
The system purges the SmartLink file cache of data that has not been accessed for the number of days specified.
