CLOUDREADCACHERETENTIONTIME
The CLOUDREADCACHERETENTIONTIME option specifies how long cloud-container storage pool data is retained in the read cache after the last read operation ends. By default, data is retained in the read cache for 10 minutes after the last read operation ends. You can use this option to specify a longer time period for data retention.
Consider specifying this option if you frequently must restore the same or similar data, and the restore operation typically takes longer than 10 minutes. If you backed up data with a high data deduplication ratio, restore operations might require more time. If you backed up data with a high data deduplication ratio, a longer retention time might benefit performance.
If the time between read operations exceeds the default setting of 10 minutes, you can specify this option the option to avoid staging the same data to the read cache repeatedly. If you plan to restore data from disk storage and more time is required, you can specify the additional time with this option to help ensure that the restore operation can be completed.
Syntax
Parameters
- data_retention_time
- Specifies the time period that cloud-container storage pool data is retained in the read cache. The default is 600 seconds (10 minutes). The minimum value is 1 second. To set the maximum value of 2147483647 seconds, specify MAX_INT. In a typical scenario, the time would be set to a few days or weeks.
Example
Increase the time period that data is retained in the cloud read cache by 10 minutes.
