Configure advanced policy settings

You can optionally configure advanced settings for a replication policy.

1. Optional: In the Priority field, specify whether the policy has priority.
   Selecting Normal will cause jobs created by the policy not to have priority. Selecting High will give priority to jobs created by the replication policy.
2. Optional: From the Log Level list, select the level of logging you want SyncIQ to perform for replication jobs.
   The following log levels are valid, listed from least to most verbose:

   • Fatal
   • Error
   • Notice
   • Info
   • Copy
   • Debug
   • Trace

   Replication logs are typically used for debugging purposes. If necessary, you can log in to a node through the command-line interface and view the contents of the /var/log/isi_migrate.log file on the node.

   NOTE The recommended log level is Notice.
3. Optional: If you want SyncIQ to perform a checksum on each file data packet that is affected by the replication policy, select the Validate File Integrity check box.

   If you enable this option, and the checksum values for a file data packet do not match, SyncIQ retransmits the affected packet.

4. Optional: To increase the speed of failback for the policy, click Prepare policy for accelerated failback performance.
   Selecting this option causes SyncIQ to perform failback configuration tasks the next time that a job is run, rather than waiting to perform those tasks during the failback process. This will reduce the amount of time needed to perform failback operations when failback is initiated.
5. Optional: To modify the length of time SyncIQ retains replication reports for the policy, in the Keep Reports For area, specify a length of time.

   After the specified expiration period has passed for a report, SyncIQ automatically deletes the report.

   Some units of time are displayed differently when you view a report than how they were originally entered. Entering a number of days that is equal to a corresponding value in weeks, months, or years results in the larger unit of time being displayed. For example, if you enter a value of 7 days, 1 week appears for that report after it is created. This change occurs because SyncIQ internally records report retention times in seconds and then converts them into days, weeks, months, or years.

6. Optional: Specify whether to record information about files that are deleted by replication jobs by selecting one of the following options:

   • Click Record when a synchronization deletes files or directories.

   • Click Do not record when a synchronization deletes files or directories.

   This option is applicable for synchronization policies only.

7. Specify how the policy replicates CloudPools SmartLink files.
   If set to Deny, SyncIQ replicates all CloudPools SmartLink files to the target cluster as SmartLink files; if the target cluster does not support CloudPools, the job will fail. If set to Force, SyncIQ replicates all SmartLink files to the target cluster as regular files. If set to Allow, SyncIQ will attempt to replicate SmartLink files to the target cluster as SmartLink files; if the target cluster does not support CloudPools, SyncIQ will replicate the SmartLink files as regular files.
