7 backup-backup
23 backup-backup-active
31 backup-backup-history
Indicates the data originated on the backup server and
was retrieved from the backup.
The suffix -active denotes the data was returned from
the active portion of the lease-state database while
-history indicates that the data was from the history
portion of the lease-state database.
When viewing leases with the UI's, you will see all four
values routinely, especially if load-balancing is enabled.
When looking at lease history records, main-main and
backup-backup are the usual values, but in cases where the
lease history poller has determined that some data may be
missing, then main-backup and backup-main can appear as
well.
