Long-term data retention

Archiving data

The Archiving and restoring data features have been added to TrueSight IT Data Analytics 11.3.01. You can archive data to external storage for long-term data retention before the data is purged. You can choose to archive data for reasons such as:

- - Regulatory compliance
  - Research or Auditing
  - Long-term analytics

Archiving involves taking a snapshot of collected data each day and storing those snapshots to a separate storage device. Restoring archived data requires a dedicated Indexer configured as a restore node. For more information, see Archiving data.

Index Blocks for data retention

Index Blocks

Data collection and retention are now defined in terms of Index Blocks. An Index Block is a term used to group indexes whose data have the same retention time and archive configurations. A group of data collectors mapped to the same Index Block would have the same archive and retention properties.

Marking different data collectors in Index Blocks of the same retention period and archive properties enables faster management of data purging. You can associate a data collector to an of the out-of-the-box Index Blocks or create custom Index Blocks, each having a configurable retention period and archive. For more information, see Understanding Indexers, Indexes and Index Blocks.

Self-health monitoring

Self-health monitoring of TrueSight IT Data Analytics

Self-health monitoring can provide early insights into the health of a component and this, in turn, provides an early insight into likely issues. TrueSight IT Data Analytics now generates events and displays them in the destination that you set. TrueSight IT Data Analytics sends self-health monitoring events for archiving and purging.

For more information, see Monitoring self-health of IT Data Analytics.
