could you please check if there're some duplicate names in $DBArray ?
and could you please try to run a failed backup in a standard non-threaded way, and check if the backup was executed twice ?
btw, is invoke-sqlcmd
thread safe ?
and.. in the beginning I see getDBListSQL
function but do not see usage of it
$DBArray = getDBListSQL
?
$DBArray.count -eq ($DBArray|sort -un).count
?
Hi Both
Thanks for taking the time to help.
MVKozlov Yes, I use it to populate $DBArray, in trying to provide a simplified code example I missed that out, thanks for noting.
copdips, there are no duplicates, in my case there are 4 databases for testing, if I use a path that exists, each database gets a single backup as expected. I did however check your second suggestion and found it indeed does try to run it twice even outside start-rsjob. I had never encountered this before so thought the threading was the more likely issue.
The issue and patches can be found here: https://support.microsoft.com/en-us/help/4010159/fix-invoke-sqlcmd-cmdlet-executes-a-query-statement-multiple-times-if
I will install CU and check it resolves my issue. Again thank you both for your time!
Cheers Mat
I can confirm this issue was resolved by the patch. Thanks both!
Do you want to request a feature or report a bug? Bug, I think... What is the current behavior?
I am running some backups of SQL Server databases, via a function, within start-rsjob. When the backups are successful, it works as expected. I get a single backup for each database. When the backups encounter and error, they are run twice, I get two separate attempts to backup each database. I have ran a trace on the SQL Server and can see the multiple backup commands coming in.
If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
What is the expected behavior? I expect the command to fail and not be re-run/retried.
Which versions of Powershell and which OS are affected by this issue? Did this work in previous versions of our scripts?
Please provide a code example showing the issue, if applicable:
