Description

DAOS_Enabled activates DAOS (Domino Attachment and Object Service). DAOS externalizes large, recurring file attachments from NSFs into a shared repository (*.nlo files) and only references them. On servers with heavy mail and attachment volumes, this saves considerable storage space and reduces the backup volume.

Example configuration

DAOS_Enabled=1 DAOS_Base_Path=D:\DAOS DAOS_MinObjSize=64000

Notes & pitfalls

  • Prerequisite: transaction logging must be enabled (TRANSLOG_Status=1) and set to Archive style.
  • Databases must be individually configured as DAOS-enabled (Database Properties → Advanced → DAOS).
  • The DAOS repository must absolutely be included in the backup – without the *.nlo files, the attachments are lost.
  • Configure DAOS at the server level; do not switch it on/off per cluster replica.
  • Activation happens at runtime via the Server document; the notes.ini is the underlying entry.
