Hello,
I have a full backup done weekly and then differential backups every 4 hours. Both backups are followed by cleanup tasks. Full backups and cleanup tasks run with no problems and so do differential backups too and their cleanup tasks, but sometimes differential backup cleanup leaves behind empty files (0 bytes in size).
I checked the logs, and differential backup tasks are completing succesfully and I can see the backup files being created too and being cleanup up too, but sometimes there are empty backup files left over. I had the same issue while using SQL Server maintenance tasks and Ola Hallengren's SQL Server Maintenance Solution. I tried googling and asking Ola too but couldn't come up with a solution.
Has anybody else had anything like this happenning or has any idea what might be causing this?
