 Description   

The cursor response, which represents the files to copy, will have a new field added named required: <bool>, indicating whether the file must be copied regardless of choice when taking a selective backup.

The following files not associated with a namespace will be marked as required:

  • WiredTiger
  • WiredTiger.backup
  • WiredTigerHS.wt
  • WiredTigerLog.*
    • Journal files.
  • _mdb_catalog.wt
  • sizeStorer.wt
  • Any collection residing in an internal database (admin, local or config).
  • Each databases system.views collection. This is necessary for time-series collections to be properly restored.
  • Files with table logging enabled. These need to be copied otherwise WiredTiger will return an error when running recovery.
