Maintenacen Plan Backup Problem

Hi:

Set up a Maintenance Plan backup job that is set to delete the backup file after 19 hours but it waits until another SQL backup job is completed before deleting the old backup file 27 hours later. (NT4 server, SQL7 SP1). Therefore the server requires space for two complete SQL backups just to hold one SQL backup. Not an issue when you have enough disk space but on very large databases 45GB+ it results in alot of wasted space.

The current workaround is to manually schedule the backup jobs TO DISK = with a nightlybackup.BAK filename. Then another job deletes that backup file at a specific time. Would like to use the maintenace plan for the detailed time stamp it labels the backup file. Any suggestions?

Thanks,
