B.3 Data Expiration Policy

This section lists the order in which Sentinel Log Manager chooses to delete data from the networked storage or from the local storage locations. Sentinel Log Manager deletes the data types in their listed order until the required space is available.

Data is deleted in the following order:

  1. All partitions (both local storage and networked storage) are deleted as soon as the keep at most time limit of their retention policy completes.

  2. Partitions that are successfully moved to networked storage (oldest first until none-left or the desired amount of space is available).

  3. Partitions that are not yet moved to networked storage, but completed their retention policy's keep at most time limit (ordered by the largest amount of time completed the keep at most limit, until none left or the desired amount of space is available).

    If at least half of the desired space is not yet been freed, then partitions are deleted prematurely, considering that the incoming data is more important than any old data.

  4. Partitions that are not moved to networked storage and completed their policy's keep at most time limit (ordered by the shortest amount of time before the keep at most limit, until none left or at least half of the desired amount of space is available, but the current UTC day partitions are not deleted).
