master..sqlbackup takes a long time to complete

I am supporting a site using SQL Backup 7.7.0.18

We are log shipping 70 databases to a remote server using the stored proc below.
Lately the stored proc continues to run for a long time after all the logs for the database have been restored and moved to the logRestored directory.

Can you give any insight into what is happening?
Does this have anything to do with the Compact database the SQL backup logs to?


Thank you
Bob

ALTER PROCEDURE [dbo].[usp_restorelog] ( @DBNAME varchar(100) )
as
BEGIN
DECLARE @errorcode INT
DECLARE @sqlerrorcode INT
declare @RestoreStr varchar(2000), @RestStr varchar(2000)
SET @RestoreStr='-SQL "RESTORE LOG [XXX] FROM DISK = ''\aso_sql2008LogShippingLogsLOG_XXX_*.sqb'' WITH STANDBY = ''C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLBackupUNDO_XXX.dat'', MOVETO = ''B:LogshippingLogsRestored'',ERASEFILES = 10, FILEOPTIONS = 1,DISCONNECT_EXISTING,MAILTO_ONERRORONLY=''[email protected]''"'
set @RestStr= Replace(@RestoreStr,'XXX',@DBNAME);

EXECUTE master..sqlbackup @RestStr, @errorcode OUT, @sqlerrorcode OUT;
IF (@errorcode >= 500) OR (@sqlerrorcode <> 0)
BEGIN
SET @RestoreStr = 'SQL Backup failed for :'+@DBNAME
print @RestoreStr
--RAISERROR ('SQL Backup failed with exit code: %d SQL error code: %d', 16, 1, @errorcode, @sqlerrorcode)
END


END

    My best guess is that the ERASEFILES option is the cause of the error. You have ERASEFILES = 10, and your restored files are moved to 'B:LogshippingLogsRestored'. You have 70 databases. Assuming you take a log backup every hour, that's 16800 files present in the 'B:LogshippingLogsRestored'. SQL Backup will need to scan all 16800 files every time it restores a transaction log in order to determine which files to delete.

    What you can do is to move each file to its own database-specific folder e.g. MOVETO = ''B:LogshippingLogsRestored<DATABASE>''. In this way, each folder will only contain files for that specific database, and a maximum of 240 files. This will speed up the deletion process greatly.

  • We are getting the same error. Wondering how was can speed things up to correct this error.

    The error indicates that the log backup you are trying to restore is too old (might had already been restored previously). You need to restore from a newer log backup.
