我想知道使用xdmp函数的marklogic数据库备份文件的大小？有什么xdmp函数可以使用吗？
declare namespace forest = "http://marklogic.com/xdmp/status/forest";
declare function local:backup-size($db as xs:string)
as xs:decimal
{
for $forests in xdmp:forest-status(xdmp:database-forests(xdmp:database($db)))
let $backup-b := sum($forests/forest:backup-write-bytes)
return $backup-b
};
fn:concat("Database backup size is: ", local:backup-size("db-name"), " Bytes")
注意：调整XQuery以包括或排除
