What is Automatic Cleaning?
Prediction Enabled Automatic Cleaning complements the existing cleaning engine by predicting system capacity and allowing cleaning to start automatically when the system predicts it meets certain capacity usage levels within a certain period instead of relying entirely on time-based cleaning schedules regardless of capacity usage or system activity.
In which operating system release has Automatic Cleaning been introduced?
Prediction-enabled Automatic cleaning is introduced in DD OS 7.6.x which is incorporated in Integration Data Protection Appliance 2.7.x.
Automatic Cleaning is available only for Active Tier.
Scheduled Automatic Cleaning or Skip Schedule
|
Fully Automatic Cleaning or Auto Schedule
|
Supported on systems with Cloud Tier
|
Not Supported on systems with Cloud Tier
|
Regular or Traditional Cleaning Schedule must be present.
|
Regular Cleaning schedule is automatically disabled once Auto Schedule is set.
|
Regular Scheduled Cleaning is skipped if system used-capacity is expected to grow beyond configured percentage within configured days.
|
Cleaning is only run if scheduled used-capacity is expected to exceed configured percentage threshold within configured days.
|
When Skip Schedule is disabled or reset, normal cleaning schedule remains as is.
|
When Auto Schedule is disabled or reset, normal cleaning schedule must be manually set.
|
What are the commands used for setting up Automatic Cleaning?
filesys clean skip schedule { [days <day(s)> estimate-percent-used <percent>] | show | reset }
# filesys clean show schedule
If the regular cleaning schedule does not exist or is set as never, use the below syntax to set it or use the DD UI path to set it:
CLI Syntax:
filesys clean set schedule { daily <time> | <day(s)> <time> | biweekly <day> <time> | monthly <day(s)> <time> }
DD UI PATH
Log in to DD UI > Data Management > Filesystem > Click the Gear Icon at the right for Settings > Go to Cleaning tab > Select Frequency, Time & day.
# filesys clean skip schedule days 10 estimate-percent-used 90
Command to display the Skip Schedule:
# filesys clean skip schedule show
Command to disable the Skip Schedule:
# filesys clean skip schedule reset
filesys clean auto schedule {[days <day(s)> estimate-percent-used <percent>]|[interval-days <days>]|show | reset }
Example:
If the requirement is to have cleaning run when system used-capacity is expected to grow beyond 85% in the next 10 days, use the below to set it:
# filesys clean auto schedule days 10 estimate-percent-used 85
Result: Automatically scheduled cleaning runs, if system-used space is estimated to grow beyond 85% in the next 10 days. Minimum days between automatically scheduled cleanings are set to seven days.
# filesys clean auto schedule days 10 estimate-percent-used 85 interval-days 5
Result: Automatically scheduled cleaning runs, if system-used space is estimated to grow beyond 85% in the next 10 days. Minimum days between automatically scheduled cleaning are set to five days.
# filesys clean show schedule Filesystem cleaning is scheduled to run "never".
# filesys clean auto schedule show
# filesys clean auto schedule reset
CLI Syntax:
filesys clean set schedule { daily <time> | <day(s)> <time> | biweekly <day> <time> | monthly <day(s)> <time> }
DD UI path:
Log in to DD UI > Data Management > Filesystem > Click on the Gear Icon at the right for Settings > Go to Cleaning tab > Select Frequency, Time & day.
