Description

During in-place compact, Domino normally creates a temporary backup copy of the NSF so that the operation can be rolled back in the event of a crash. Compact_No_Backup=1 disables this behavior: the compact run is faster and requires less disk space, at the cost of losing the rollback mechanism.
Primarily suitable for servers with an active transaction log (which itself provides a recovery layer) or when there is no space on the volume for an additional copy.

Example configuration

Compact_No_Backup=1

Notes & pitfalls

  • Without a backup: a crash during compact = potentially damaged NSF.
  • Especially useful with the transaction log enabled (TRANSLOG_Status=1).
  • Disk space: saves up to 100 % of the space currently used by the running NSF.
  • For critical databases, plan a regular backup before compact.
  • The change takes effect immediately for new compact runs.
