Summary

Validates that the specified list of forests can be backed up to the backup data directory. Optionally verifies that the list of forests can enable journal archiving to the journal archive directory with the specified lag limit. Returns a database backup set node.

Parameters
forestIDs A sequence of forest IDs.
pathname A backup data directory pathname.
include-replicas Whether or not to include replica forests
incremental-dir Path to where incremental backups are stored. Defaults to the backup data directory.
journal-archiving Whether or not to enable journal archiving
journal-archive-path Path to where archived journals are stored. Defaults to the backup data directory.
lag-limit Maximum difference in seconds that the archived journal can lag behind its forest's active journal. Defaults to 15.
