Methods

classmethod HistoryClose(ByRef qHandle As %Binary) as %Status

classmethod HistoryExecute(ByRef qHandle As %Binary, DateTimeStart As %String = "", DateTimeEnd As %String = "") as %Status

classmethod HistoryFetch(ByRef qHandle As %Binary, ByRef Row As %List, ByRef AtEnd As %Integer = 0) as %Status

Queries

query History(DateTimeStart As %String = "", DateTimeEnd As %String = "")

Selects Type As %String, Databases As %String, Time As %String, Journal As %String, LogFile As %String, Status As %String

Provides a history of all backup operations that have been executed. The results are in reverse-chronological order.

DateTimeStart is the starting datetime in $H format for the backup history. If it is a null string then the starting time is the earliest in the recorded history.
DateTimeEnd is the ending datetime in $H format for the backup history. If it is a null string then the ending time is the latest in the recorded history.

query List()

Selects Name As %String, Type As %String, Device As %String, SwitchJournal As %Boolean, Description As %String, LastModifiedTime As %String, LastRunTime As %String, Status As %String, ReadOnly As %Boolean, IsTape As %Boolean, LastLogFile As %String, StatusStr As %String

Provides a list of all currently defined tasks.
The four built-in tasks are always returned first, followed by any user-defined tasks.

LastFile only has a value if a log file exists from the last run of the backup.

query ListLogFiles(task As %String = "")

Selects Name As %String,

Returns a list of log files that exist for a specified backup task. If no task is specified, returns a list of all log files for all backup tasks.
