Answer

  • No. Only ARP/AI snapshots triggered by an I/O surge, also referred to as surge snapshots, are automatically deleted after exceeding the number of days specified by arw.snap.surge.interval.days.
  • arw.snap.surge.interval.days specifies:
    • The creation interval for ARP/AI snapshots triggered by an I/O surge
    • The retention period for I/O surge-triggered snapshots
  • The setting does not automatically delete other ARP/AI snapshots created when an attack is suspected if no attack or false-positive determination is made.
