Which history block storage locations need to be manually backed up?

The history block storage locations that need to be manually backed up are both the Alternate and Circular storage locations.

Circular storage locations are designed to overwrite old data once the storage limit is reached. Since this method continuously updates the existing data, it is crucial to manually back up the data before it is overwritten, especially if the data holds significant historical value. If backups are not performed, valuable historical data could be permanently lost when new data is recorded.

Alternate storage is also critical to back up manually because it is used for retaining different versions or sets of data that may not be immediately relevant but could be essential for future analysis or audits. Manual backups ensure that these alternate versions of the data are preserved and can be referred back to when required.

Thus, both storage locations require manual backup efforts to safeguard against data loss, ensuring that comprehensive historical data is maintained.
