These thresholds determine the point at which StorNext applies or stops applying truncation. Watermarks help you determine disk space thresholds for your file system. Specify any filenames you want excluded from the truncation process. Specify the minimum size a file must be in order to be eligible for truncation. Specify the interval of time for a file to remain idle before truncation begins. The Truncation portion of the Deduplication tab contains the following fields: ParameterĬlick the button beside this field to turn truncation on or off. In this case Storage Manager truncation performs any required truncation, but Storage Manager will not truncate a file unless the StorNext truncation parameters have also been satisfied. Note: If a Deduplication-enabled directory is also a Storage Manager relation point, both StorNext and Storage Manager truncation concepts apply. The Deduplication tab also contains fields which enable you to enter parameters related to data truncation as it applies to deduplication. Only use filtering if you are storing this type of file in the policy. When metadata content filtering is enabled, the Deduplication engine will attempt to interpret the content of various backup file formats such as tar and netbackup to extract the component files and apply deduplication algorithms to them. Preference is given to files from policies with a lower priority number when StorNext considers deduplication candidates. If desired, indicate relative deduplication priority. Specify any filenames you want excluded from the deduplication process. Specify the minimum size a file must be in order to be eligible for deduplication. This field uses the format 00:00:00:00, which refers to days:hours:minutes:seconds. Specify the interval of time for a file to remain idle before deduplication begins. Minimum File Idle Time Before Deduplication Note: This field appears only when editing the Replication / Deduplication policy named "Global." To change the virtual IP address from "localhost" you must edit the “Global” policy. Additionally, you must edit the "Global" policy on every file system that has a replication/deduplication policy.

When you are finished entering information about the new policy, click Apply, or click Cancel to exit without saving.Īfter a message informs you that the policy was created successfully, click OK. (See the sections following for more information about fields on these tabs.)
