I'm using Powershell to check last backup times across all our sqlserver databases. This seems to work really well, but I've got a question If I run this (a cut-down version of the actual script): dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate I get: Parent Name LastBackupDate ------ ---- -------------- [Server1] ADBA 10/09/2012 21:15:37 [Server1] ReportServer 10/09/2012 21:00:17 [Server1] ReportServerTempDB 10/09/2012 21:00:18 [Server1] db1 10/09/2012 21:15:35 If I then run a sql backup of the Server1 default instance, and run the same query the last backup date doesn't change: PS C:\temp> dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate Parent Name LastBackupDate ------ ---- -------------- [Server1] ADBA 10/09/2012 21:15:37 [Server1] ReportServer 10/09/2012 21:00:17 [Server1] ReportServerTempDB 10/09/2012 21:00:18 [Server1] db1 10/09/2012 21:15:35 ..but if I open a new powershell window, it shows the backup I just took: PS SQLSERVER:\> dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate Parent Name LastBackupDate ------ ---- -------------- [server1] ADBA 12/09/2012 09:03:23 [server1] ReportServer 12/09/2012 08:48:03 [server1] ReportServerTempDB 12/09/2012 08:48:04 [server1] db1 12/09/2012 09:03:21 My guess is that this is expected behaviour, but could anybody show me where it's documented/explained - I just want to understand what's going on. This is running the SQlps which came with 2008, against a 2008 instance. Thanks Matt
